Who are the Lethal Legion
The Lethal Legion is a villain team with one job: fight the Avengers. It first appeared in Avengers #78, cover-dated July 1970, by Roy Thomas and Sal Buscema, and it has come back many times since, almost never with the same roster. The name is the constant; the membership is whatever the current leader can recruit.
The Grim Reaper’s Legion (1970)
The original was assembled by the Grim Reaper, brother of the Avenger Wonder Man, as a revenge squad. It set the pattern: a grudge-holding leader gathers a handful of villains, throws them at the Avengers, and loses.
Later versions
Roster: different each time, often led by the Grim Reaper or Count Nefaria.
Writers have revived the Lethal Legion repeatedly as a plug-and-play threat, swapping in whatever villains suit the story. Count Nefaria’s version is among the better-known later lineups. Because the team is defined by its purpose rather than its members, no single roster is definitive.

For collectors
The key is Avengers #78 (1970), the first appearance. The Lethal Legion is a recurring story device more than a collector draw, so value sits with that Bronze Age debut rather than later reassemblies.
