I've been rewatching the older DCU animated movies. This and Superman Unbound are queued up next.
I've always been partial to the evil Superwoman (voiced by Gina Torres) in Justice League: Crisis of two Earths.
Here's a sample:
I loved how effortlessly powerful she is. She just wades through things with evil glee.
the voice acting is a bit iffy on it, I don't like William Baldwin's Batman, James Woods is creepy as Owl man.
