Editing Legion of Doom (section)

==Other Legion episodes==
While ''Challenge of the Superfriends'' was the series spotlighting the Legion of Doom, they appear in a few ''Super Friends'' shorts:
* "The Krypton Syndrome": After Superman saves Krypton in the past, he returns to an alternate present. Robin mentions that the Super Friends were defeated by the Legion of Doom.
* "Two Gleeks are Deadlier Than One": Though only Giganta and Gorilla Grodd appear, the Legion of Doom is mentioned where the Super Friends investigate rumors that the Legion of Doom are getting back together. Like in "Super Friends: Rest in Peace", the Super Friends used androids to trick Giganta and Gorilla Grodd into thinking they were destroyed.
* "The Revenge of Doom" (''[[Super Friends (1980 TV series)|Super Friends]]'' short): All 13 members of the Legion of Doom appear after getting back together, but only Lex Luthor, Sinestro and Solomon Grundy have dialogue. In this appearance, they salvaged the Hall of Doom disguised as construction workers with the cover-up that they were going to turn it into a museum. Batman and Robin came upon the "construction workers" and demanded to see their permit, which they did, having been obtained by the Department of Parks. When there was a mentioning that the Ion Engines were removed by the Super Friends which would've made it the first flying museum, the Dynamic Duo gets suspicious about the construction workers learning about the top secret operation as the lead construction worker claims that the info of that might've been leaked to the news. With the plot exposed, Lex Luthor and the Legion of Doom shed their disguises and capture Batman and Robin. After refurbishing the Hall of Doom and equipping it with new weapons, they have developed a crystallizing ray to immobilize Superman and Wonder Woman. Batman and Robin eventually escape, reverse the effects of the crystallizing ray on Superman and Wonder Woman, and apprehend the Legion of Doom.

Members of the team have solo appearances in later episodes.
