The Avengers got their own cartoon on Fox Kids in 1999. The show only lasted one season and 13 episodes. The team members were given revamps in their appearances, in many cases gaining armoured costumes with in-built weaponry.

Thanks to Arthur Jr. for additions to the appearance list. He mentions "When Avengers was cancelled, at the same time, a proposed Season 2 was being written out which would've featured Thor and his archenemy Loki and a 2-part team-up with the X-Men (including Morph from the 1990s cartoon)."
