This is animated versions of both. Supes from the Superman/Doomsday animated movie and Hulk from the recently released Planet Hulk movie, which was quite epic. Tired of the same old comic fights and series battles. This time it's just goin by what they could do in their own movies, and yes Planet Hulk seems to be separate from the Hulk vs. movies (or maybe not, but I don't wanna get into that). So instead of an awakened Doomsday, Supes has to contend against King Hulk, the Sakaarson, the Worldbreaker.
