Hulk Vs./绿巨人大战

Actually these are two respective animations: Hulk vs. Thor and Hulk vs. Wolverine, which have no connections in stories with each other, factually two different animations.

In the part of Hulk vs. Wolverine, actually there is little fight between the two, while more about their fight against their mutual enemies. In the part of Hulk vs. Thor, Hulk beat Loki, Thor and other gods and almost destroyed Asgard before the gods had to refer to Hela, the daughter of Loki and the Asgardian goddess of death to stop him.

Well, after watching the two animations, you would find Hulk is really invincible, that's the reason why I don't agree the ranking here which says Thor is more powerful than Hulk.
