The Durlans and R.J. Brande

X-Plam and the chameleon people of 24th century Earth. From Superman #136 (Apr. 1960); by Robert Bernstein, Wayne Boring and Stan Kaye.
The Durlan is young Dox's sole confidant. From L.E.G.I.O.N. # (); by .

The Durlan

The being known only as the Durlan was the first of his race to leave his homeworld, Durla, a planet of non-humanoid shape-shifters. Apparently, at this time in Durlan society, it was not common for individuals to take their own names. Indeed, some Durlan customs were invented in response to their progressive development and contact with alien races. Outside Durla, Durlans are regarded with great suspicion because of their abilities. On this secluded world, natives were discouraged from outside contact, perhaps for good reason.

Heedless to the dangers, "the Durlan" left in search of adventure, but soon crash landed on the planet Colu. Instead of enlightenment, the creature was doomed to a life of slavery under the evil Vril Dox — Brainiac. The elder Dox was a lead scientist on Colu, where emotion had long been banished in favor of science. Dox's son, Vril II was also treated like little more than a slave, and so the Durlan and the young Dox's became each others' only support.

Over the course of a decade, the Durlan and Dox became the best friends. As Dox's companion (and occasional test subject) the Durlan served much like the angel on Dox's shoulder, in stark opposition to Dox's father. At times, the Durlan would take a more humanoid form, which his people find puts humanoids more at ease.

When Vril's father was discorporated by the angry Computer Tyrants of Colu, Dox the second was given over to the Dominators as a good faith gesture of their neutrality in the war against Earth. The Durlan also stowed away inside Dox's body. (L.E.G.I.O.N. #23)

From inside the Starlag prison, Dox, along with Adam Strange, the Omega Men and other captives became instrumental in the downfall of Dominators' invasion alliance (which, oddly, included Durla). (Invasion! #1) During this time, they also met their future comrades, Garryn Bek of Cairn, Stealth, Lyrissa Mallor of Talok VIII and Strata of Dryad. (#2)

After their victory, Dox led his new allies back to Colu where he overthrew the Computer Tyrants. (L.E.G.I.O.N. #1-3) Dox was emboldened by this success and it gave him the idea to form a new police force to replace the former Green Lantern Corps. Their friends from Starlag were hesitant at first to join Dox, but ultimately decided that it might be a good idea to stick around to eye on him. They set up camp on Bek's homeworld of Cairn, and soon began contracting their services as the L.E.G.I.O.N. (Licensed Extra-Governmental Interstellar Operatives Network) (#5-12)

The Durlan often served as the calm in the L.E.G.I.O.N.'s storm. Not only was he Dox's steady confidant and advisor, but he aided the team as a medical technician. After Stealth went into a rage and attacked Dox, the Durlan described her as a "unique life form" — and informed her she was pregnant with Dox's child.

Very soon after this, with Dox still in recovery, the Durlan disappeared forever, without explanation. In his place was a mystery woman with phasing ability. (#9)

When Dox recovered, he was grief-stricken at his only friend's disappearance. Though to most Dox was a cold man, the Durlan's influence remains strong inside him. His teachings return often in the form of Dox's conscience.

30th Century: The Daggle Family of Durla

The planet Durla is a nuclear wasteland, the legacy of a so-called "Six Minute War." There, the shape-changing natives are prone to xenophobia and rarely leave their own world.

Ren Daggle and his mate, Zhay, mated in the Durlan way. Each simultaneously impregnates each other, which results in twin births. Their twin sons were Reep and Liggt Daggle. At some point after their birth, Ren and Zhay contracted Yorggian Fever and Zhay died. Ren survived the fever and left his sons in the care of his sister, Ji, who raised them as her own children..

Ren and his brother, Theg, were eventually robbed of their ability to shape-change and became frozen in human form. In these forms, they took the identities of Rene Jacques (R. J.) Brande and Doyle Brande, and formed Brande Industries.

X-Plam

Just prior to Chameleon Boy's debut, a story was published featuring bald, green-skinned people with antennae. In Superman #136 (Apr. 1960), Superman and Lois Lane met X-Plam, who was actually from 24th century Earth, when humans had evolved to look this way. The two stories had different creative teams, but editor Mort Weisinger plotted all Silver Age Superman stories.

Chameleon Boy

The planet Durla is a nuclear wasteland, the legacy of a so-called "Six Minute War." There, the shape-changing natives are prone to xenophobia and rarely leave their own world.

Ren Daggle and his mate, Zhay, mated in the Durlan way. Each simultaneously impregnates each other, which results in twin births. Their twin sons were Reep and Liggt Daggle. At some point after their birth, Ren and Zhay contracted Yorggian Fever and Zhay died. Ren survived the fever and left his sons in the care of his sister, Ji, who raised them as her own children. Note: Chameleon Boy's name and homeworld were revealed in Superman Annual #4 (1961).

Ren and his brother, Theg, were eventually robbed of their ability to shape-change and became frozen in human form. In these forms, they took the identities of Rene Jacques (R. J.) Brande and Doyle Brande, and formed Brande Industries.

On Durla, tradition mandated that twins must fight one another to the death to prove their worthiness to survive. Reep Daggle killed his brother Liggt in this ritual but he was so traumatized by the barbarity that he vowed to never kill again. (Legion vol. 4 #8) Note: These details about the Daggle family were revealed during the Glorith Reality era.

With his parents’ permission, he left Durla to apply for membership in the Legion of Super-Heroes. But Durlans are an isolationist race, perhaps because other species often regard their abilities with nervous suspicion. Reep was determined to defy this phobia and foster respect for his race. Now, the Legion was funded by R.J. Brande, but Reep's father did not reveal himself to his son as such. Brande worked with his assistant, Marla Latham, to recruit Reep for the Legion membership.

Regardless of covert nepotism, the Legionnaires valued Reep's ability and he was admitted to the team. But when asked what name he would use as a super-lawman, Reep was stumped. But his fellow inductee, Colossal Boy, noted that Reep’s power reminded him of Earth's chameleons, which could change their color. Reep Daggle thus became known throughout the galaxy as Chameleon Boy. (Adventure Comics #350, Legion of Super-Heroes vol. 3 #39) The young heroes became best friends for the duration of their Legion membership. (Action #267)

"Cham," as he was called, became a great asset to the Legion, as he was a natural spy, and his keen intelligence and sense of observation made him particularly fit to lead the Legion Espionage Squad. (Adventure #360)

Reep never seemed to prioritize his romantic life. He once had a chance at true love on the other-dimensional world of Nadir. There he defeated Kodar the Black Vassal and romanced Princess Elwinda. He wanted to marry her, but when her father found out, he ordered Cham's execution. The Legionnaires teleported him out just in time, but it was bittersweet knowing he wouldn't see her again. (#376)

Cham learned the truth about R. J. Brande when the Legion's founder fell ill with Yorrgian fever, and, in search of a suitable blood donor, the Legion uncovered the fact that Cham was R.J. Brande's son. He understood why his father had to abandon him on Durla, but he was bitter that Brande had kept this secret for so many years. (Secrets of the Legion #1-3)

His anger led Chameleon Boy to act out; he ordered a dangerous Espionage Squad mission to Khundia, and almost set off a war. (Legion vol. 2 #286) This mission earned Cham a criminal charge, and he was sentenced to Takron-Galtos (#290, 292), where he was fitted with a device on his antennae that inhibited the use of his power. (#296) During the galaxywide threat of Darkseid's "Great Darkness," Reep helped quelling the riots inside the prison when, even taking on the powerful Daxamite, Ol-Vir. (#294)

Reep was awarded with clemency for his actions, but to his horror he discovered that his shape-changing abilities had been diminished from prolonged use of the inhibitor device. He and his father took a trip back to Durla to restore his powers. The trip was successful, and father and son were reconciled during that time (though Brande declined the opportunity to restore his own native powers). (#298, 301)

Other Chameleons

The “Chameleon Men,” Jan-Dex and Zo-Gar, are members of the Legion of Super-Outlaws. From Action Comics #283 (Dec. 1961); by Robert Bernstein, Curt Swan and Stan Kaye.
"Chameleon Chief" and Sun Emperor join the Legion of Super-Villains. From Superman's Pal Jimmy Olsen #63 (1962); by Jerry Siegel, Curt Swan and George Klein.
Chameleon Kid becomes just one of a Legion of Super-Rejects. From Superboy #212 (Oct. 1975); by Jim Shooter and Mike Grell.

Two "Adult Legion" stories contained adult "chameleon men" who were members of the adult Legion of Super-Villains. The first was Action Comics #283 (Dec. 1961), which featured two “Chameleon Men” named Jan-Dex and Zo-Gar. They were garbed in a fashion identical to Chameleon Boy’s costume and came to Earth looking for Kryptonite. They planned to destroy Superman as part of a Legion of Super-Outlaws. Superman outwitted them and returned them to the authorities in the 30th century.

This was just months after the debut of the LSV, in Superman vol. 1 #147 (Aug. 1961). Since they also referenced Cosmic King and Lightning Lord, one assumes the Chameleon Men were referring to the LSV but that the writers at the time were oblivious to the name discrepancy.

Then in Superman's Pal, Jimmy Olsen #63 (Sept. 1962), someone called "Chameleon Chief" was a member of the adult LSV. This character was dressed differently but could have been considered one of the Chameleon Men.

Many years later, after the teen (canonical) LSV was introduced (Adventure Comics #372, Sept. 1968), Chamelon Chief was a member of this team too (Superboy #208, Apr. 1975). But he was later given the name "Jall Tannuz" and was identified as a non-Durlan. (Who's Who in the Legion #4)

Just a few issues later, a similar group called the Legion of Super-Rejects rose to challenge the Legionnaires. These rejects all hailed from the same planets as current Legionnaires and had the same powers. Among them was Chameleon Kid, Toog Lintens of Durla. Some of the Rejects became Super-Villains but Chameleon Kid was never heard from again. (Superboy #212, Oct. 1975)

Glorith Reality

In Glorith Reality continuity, Cham went on to head his father's company, and was the driving force behind the Legion as well …

He stayed with the Legion until the U. P.'s economy collapsed, taking Brande Industries with it. R. J., who had disappeared several years earlier, named him to take over the corporation and try to get it, and the galactic economy back into shape. Chameleon Boy had to honor his father's wishes, and he watched from the sidelines as member after membe:r of the Legion dropped out, Earthgov hounded the Legion, and finally, the team disbanded. He harbored hope of re-creating the Legion, and in 2994, he saw a window of opportunity. He recruited Rokk Krinn, Jo Nah, and two of Jo's associates, Kono and Furball, and the five went to rescue Mysa Nal from Mordru. After doing this (and getting Rond Vidar as well), he linked up with more former Legionnaires on Winath, and, after capturing Roxxas the Butcher, he officially re-formed the Legion. But somehow, the feeling that he remembered from his youth was not recaptured. The adult Legionnaires were more jaded and cynical, and too far removed from the youthful idealism he once knew. Thus, when he discovered the existence of the teenagers who emerged from Batch SW6, he decided to help them find their place in the new world rather than continue with the adults. He got Jacques Foccart to replace him with the older Legion, changed his name to "Chameleon" and became the younger Legion's "adult advisor" and financier.

The Chameleon Boy of Batch SW6 was killed in the explosion of Dominion underground chambers along with the SW6 Princess Projectra and Karate Kid.

The galaxy learns the truth. From Legion of Three Worlds #1 (2009); art by George Pérez.

Reep lost his father, R. j. Brande, who was killed by his rival, Leland McCauley, acting as an agent of the Time Trapper. (Final Crisis: Legion of Three Worlds #1) To fulfill his father's last will, Chameleon Boy led the Legion Espionage Squad back to the 21st century in order to shepherd the hero Mon-El on to his destiny (among other things). Cham disguised himself as "Control," the commander of Metropolis’ Science Police. (Superman #677)

There he was able to manipulate the organization, covering fellow Legionnaires Quislet and Sensor Girl, and hiring Mon-El himself, eventually. (#686-687) His cover was blown when a bomb took out the S.P. headquarters. He revealed himself to the Guardian and to Mon-El, but retreated in order to regroup with his fellow Legionnaires. (#696-697)

Notes

Jim Shooter on Chameleon Boy:

"Hmm. A little paranoid, but he is a fighter. He knows people stare at him, but he is almost defiant. His personality is reminiscent of a slightly militant black, circa 1969. His relationship with Proty I and II should not be overblown. Cham of all people would not patronize a truly intelligent creature. Despite the Weisinger-era "dialogye" of the Proteans, I suspect they communicate simple feelings or pictures and are not human-equivalent. I doubt he resents L.L., but he may be jealous of Saturn Girl's rapport with Proty, his pet. Cham is unique, for a shape shifter he can identify with beauty the other Legionnaires misss. He could turn up with a shaggy, horned alien chick as easily as Elwinda. Liberal, he is—even philosophical. And probably a little kinky." —Interlac (1976)

Tom Bierbaum on Chameleon Boy:

"Cham became quite a three-dimensional character for me based on his relationship to Brande. The personal pride he took in the Legion, the tension between trying to be a responsible corporate "suit" and the fun-loving guy we knew in the Legion's earlier days, the quest to track down his missing father, etc." —It's OK I'm a Senator

Tom and Mary Bierbaum on Chameleon Boy:

"Another collection of contradictions. Mysterious, unfathomable, utterly alien, the consummate detective and spy. But also emotionally vulnerable, especially in matters involving anti-alien bigotry and the secretive father who "abandoned" him, R.J. Brande. Cham lacks the patience to really enjoy the leadership positions he's thrust into." —Interlac (2000)

Powers

On the distant planet Durla, the dominant race evolved a remarkable means of survival, the ability to change their forms into anything they desired. When they travel away from Durla, they adopt a generally-agreed upon form that is more humanoid in appearance: golden, hairless skin, large pointed ears and antennae on their foreheads.

These antennae act as "scanners" — when they encounter an unfamiliar object, his antennae emit invisible waves which return to the ears, and allow them to mimic that form — but not its chemical makeup.

A Durlan's power can be inhibited by placing a "collar" on their antennae, or by using a compound called Cancelite.

Durlan bodies are less dense than other species, which aids in their ability to compress and expand their forms. They can also alter the internal physiology their forms. For example, Reep once survived a shot to the head because he had distributed his brain and central nervous system throughout all cells in his body. In this way, the severity of an injury has more to with the amount of tissue loss in the body.

Cells in a Durlan body are constantly renewing themselves, which results in extended longevity.

Chameleon Boy's counterpart from Earth-247 went only by the code name Chameleon. Universe-247 was destroyed in the Infinite Crisis, but Chameleon survived along with his Legion…

Reep Daggle was born into the priestly class of the religion on his native planet, Durla. For this reason, he was selected to use his inherent shape-changing powers to represent his planet in the Legion of Super-Heroes as Chameleon. (Legion #62)

At first, Chameleon was shunned by other Legionnaires because he die not speak the Interlac language. But one Legionnaire, Invisible Kid, befriended him and helped him acclimate. Because of his adaptable nature, Chameleon actually learned Interlac very quickly, but used his perceived ignorance to his advantage for a while.

Shortly after Chameleon joined the Legion, his family was killed by another Durlan, the Composite Man. The Legion came to his aid at great risk (Saturn Girl was traumatized psychically by the battle). (#69) As the last surviving member of his clan, Reep was expected to fulfill his father 's responsibilities. He managed to forestall this destiny and was a key player in exposing the United Planets' corrupt President President Chu. (#80)

Chameleon harbors feelings for his fellow Legionnaire Spark, who was initially horrified to learn that he was her secret admirer. (#81) Yet over time, Ayla has grown more fond of him. He has also dated Sensor, but the two of them agreed mutually that they would be better as friends. (Legionnaires #46)

Reep was ultimately asked to return to Durla as its rightful spiritual leader. He returned home just as the planet was under siege from the Dark Circle. At the successful conclusion of this conflict, he was unexpectedly absolved of his duties. The strife created by the Dark Circle led the Durlans to reevaluate their position among the United Planets. A new spiritual leader named Leeja emerged to fill this role and lead Durla to better cooperation among peoples. (#65)

Chameleon proved that he had the mettle to be the ultimate survivor when the alien Blight possessed the population of Earth. The Legion's battle with this race left Earth devastated and Chameleon was one of a group of Legionnaires who were thrust through a rift in space to a galaxy much far

Notes

Olivier Coipel on Chameleon: "I think I'd get along well with Chameleon. He is the one who'd make me laugh but still be serious when the situation called for that. Maybe he's not a joker in all the stories, but I so seem him as fun guy who is also very thin, but not too tall." —Comic Book Resources

In Reboot continuity, there was no relationship between Chameleon and R.J. Brande.

Powers

Reep Daggle has the native Durlan ability to change his shapes. His antennae act as "scanners" — when they encounter an unfamiliar object, his antennae collect information so that it can be replicated. Chameleon Boy can mimic any form, but not its chemical makeup.

A Durlan's power can be inhibited by placing a "collar" on their antennae, or by using a compound called Cancelite.

Threeboot: Chameleon III

Chameleon's powers work by passively 'scanning' any new object he encounters. From Legion of Super-Heroes vol. 5 #7 (2005); art by Barry Kitson.

Reep Daggle is one of a race of asexual shape shifters. Because of their lack of gender, and their ability to take any form, Durlans are usually suspect in United Planets society. By nature, Reep is inquisitive; when he encounters new forms of life, his antennae automatically manifest to "scan" the object or being. (#15)

This ability was useful in another unexpected way, when the Legion was trailing Lemnos, a villain who could mask his presence. Chameleon's ability passively detected Lemnos' presence, which alerted the Lgeionnaires. (#7)

Disguise comes naturally to Reep. He thinks nothing of impersonating others and enjoys pranking others with his powers. As if life in the Legion weren't busy enough, Chameleon began moonlighting as a Science Police officer. (#18) He investigated a traitor among the S.P.s who was jailed but then murdered. To solve the case, he was teamed with a Titanian, Jeyra Entinn. Jeyra's telepathy found him out, but she had secrets of her own. By the time Cham realized that Jeyra was the killer, she had framed him for the crime, and he was jailed. Chameleon ultimately outwitted her. (#19)

Powers

The Chameleon of Earth-Prime is potentially more powerful. When he changes, he also mimics the physical properties of the thing he imitates. Brainiac 5 once asked Chameleon to replicate an alien weapon—then chopped off the replica off from his arm! Though this wasn't painless, Cham was actually reasonably unphased. (#46)

Other Versions

Animated Chameleon Boy

Chameleon Boy has appeared in all of the team's various animated outings.

The first animated Chameleon Boy from "New Kids in Town,"Superman: The Animated Series, season 3, episode 3 (31 Oct. 1998).
Animated Chameleon Boy. From "Chained Lightning," Legion of Super-Heroes season 2, episode 4.
From Bongo Comics Presents Futurama Comics #31 ([May] 2007); by Ian Boothby, Mike Kazaleh and Andrew Pepoy.
From Young Justice, season 4, episode 3 (21 Oct. 2021).

Superman: The Animated Series

When the Legion made its first animated appearance, it was not the classic three founders, but Chameleon Boy, Saturn Girl and Brainiac 5 who went back to meet the teenage Clark Kent. This was in "New Kids In Town," Superman: The Animated Series, season 3, episode 3 (31 Oct. 1998).

Legion of Super-Heroes Animated Series

Chameleon Boy was a featured member who was introduced in the second season of TV's Legion of Super-Heroes cartoon. He was voiced by Alexander Polinsky.

The character was a new addition (and member) in the second season. He was played as quite "green," and struggled to prove himself among the Legionnaires. Chameleon Boy played a featured role in Season 2, episode 6 (3 Nov. 2007), when Brainiac 5 sent him undercover as the Persuader, to spy on Imperiex. The real Persuader escapes from Legion HQ and finds Cham, calling him out. The Legion discovers they have also been infiltrated by the LSV's Ron Karr. Karr is disguised as Superman and tells them of Imperiex's plan to invade Cham's homeworld of Durla. Ron Karr helps them stop Imperiex's missiles.

The ninth episode of season 2 (8 Mar. 2008) told the Legion's origin and introduced the team's founder, R. J. Brande is publicly honored (and revealed as Chameleon Boy's father). His old associate, Doyle dispatches Grimbor to kill him. Grimbor kidnaps Brande and the fight leads to Brande Industries' Stellar Nurseries, where stars are manufactured. The Legion frees Brande and captures the villains.

Justice League vs. the Fatal Five

Cham did little more than cameo in Justice League vs. the Fatal Five is a 2019 feature-length animated movie. The Legion's depiction seems to also be in line with their appearance in the Justice League animated series.

Young Justice

Again Chameleon Boy was one of three visitors to the 21st century, in the fourth season of Young Justice. He, Saturn Girl and Phantom Girl … "Volatile," Young Justice, season 4, episode 3 (21 Oct. 2021).

Futurama

When the Futurama team encountes a bunch of wormholes, all sorts of (familiar) strangers emerge, including an orange alien with antennae and a blue uniform.
