The Justice League of America - Bad Day On Black Mountain

Great voice talent , cool music , fun memories. Thanks , much appreciated

My God. Superman killed Mastermind. Did ANYONE NOT even notice that? DAAAAAAAAAAANM. That was the greatest Justice League cartoon. EVER. This team kicked azz.

hanna-barberas cartoons from the sixties were brilliant but also kinda dark.

poor 60's kids , this cartoon sucked. if you showed the kids of the sixties one episode of JLU theyd crap in thier pants. i think the 60's spider-man cartoon was the best carotoon fo the sixties

Hey, jackass! If you don't like my cartoons, don't watch them! Go watch that CRAPPY new cartoons that you like and leave me alone! These old cartoon shows are GREAT, but these FUCKIN' modern productions are just for people like you!

"if you showed the kids of the sixties one episode of JLU theyd crap in thier pants." That speaks poorly about those kids, not this cartoon. If they spent their childhood watching spindly-limbed freaks "drawn" by todays computer animators, it would be quite a shock to their system to see an old cartoon where animators actually had the talent to even draw a proportioned human figure.

I agree with you, partner!

Somehow MasterMind knows the secret identities of the Justice League heroes. He also just happens to have all of their phone numbers. Hhhhmmm. After spending years hidden away on an uncharted asteroid perfecting his 'Master Plot' to take over Earth, he tells the Justice League every detail of his evil plans. And then he warns them to not try to stop him. In the next episode, Mastermind's name is changed to, 'IncompetentMind.'
