Super Friends continuity
◾ Bizarro No. 1
◾ Black Manta
◾ Brainiac
◾ Captain Cold
◾ Cheetah
◾ Giganta
◾ Gorilla Grodd
◾ Lex Luthor
◾ Riddler
◾ Scarecrow
◾ Sinestro

--this was a very eclectic lineup, especially given that the JL in this series had NEW characters in it. 3 Superman villains! While it was ostensibly 11 on 13, several members of the Legion weren't formidable in combat.
Legion of Doom (Justice League: Doom continuity)
◾ Vandal Savage
◾ Bane
◾ Cheetah
◾ Ma'alefa'ak Jonzz
◾ Metallo
◾ Mirror Master
◾ Star Sapphire(Carol Ferris)
--7 on 7 fight? oh yes! Batman, Wonder Woman, Martian Manhunter, Superman, Flash, and Green Lantern. Pretty obvious what League Vandal wanted to oppose.
Injustice League Unlimited (New Earth continuity)

◾ Cheetah
◾ Doctor Light
◾ Fatality
◾ Gorilla Grodd
◾ Joker

◾ Poison Ivy
◾ Shadow-Thief
◾ Shaggy Man
(actually this is just the core team, there was a total of 55 members!!!) I did kinda like that there was a lot of relatively new characters like Double Dare. Although, they're not exactly terrifying or powerful, it's nice having villains who aren't top tier mixed in too.(even if they strike me more as teenagers who need a guidance counselor more than prison)
