I don't need to cover things like Legion action figures, checklists, and their animated history, because one site does it so well…
- Legion Omnicom (no longer maintained):
These were a retailer's incentive shipped along with Legionnaires #50 (1997). This was the double-sized finale of the "wedding" of Mordu and Emerald Violet.
+ Vs. System: Legion of Super-Heroes (Game/Trading Cards)
These fantasy game cards are made to work with other sets of the Vs. System. The Legion set was also sold alongside a play mat (above). Inever played the game but loved the original art on these cards. Complete sets are rarely sold since the game is still being played. The game was discontinued by Upper Deck Entertainment in January 2009.
This was considered an "expansion set" and cards had the prefix "DLS" (DC Legion Super-heroes).
Alternate "stacker" cards were designed to form a triptych (above). These versions are as rare as a foil version of the same card. Every card in the set has a rarer, alternate foil version.
The set was rounded out by a fair number of Teen Titans and other team-related cards.
