While there are occasional deaths in American Animated, how often does suicide occur? And I mean the character dies as a result of suicide, not attempting it and decides to go on living. So far, the only one I recall is Spider-Carnage on Spider-Man TAS. He hops into a portal that leads to his death, because he couldn't rid himself of the Carnage Symbiote. Batman Beyond "Meltdown" Mr. Freeze successfully attempts suicide after discovering that his new body was reverting to the condition of his old one. He does so, by bringing down a building on himself, and there's a hole in his suit.
