At the SDCC '13 Press conference for Guardians of the Galaxy, Zoe Saldana expressed her views on the shared Universe and mentioned, "We're different than the Avengers," insists Zoe Saldana. "The Guardians have much 'bigger' powers. We could totally kick Thor and Captain America's ass."
Dave Bautista agreed in a later interview stating, "Drax could definitely beat up Hulk and Thor." Seemingly in an effort to differentiate his warrior character and the Hulk, Bautista adds, "Drax is an interesting creature. He's full of rage and he's full of honor. But the best thing about Drax is he's hysterical, without really meaning to be."
Honestly, I think Zoe and definitely Dave have not picked up a comic at all. I do however agree with Zoe's comment on how the Guardians powers are very different (even Joss Whedon agrees that The Avengers powers are too 'punchy'). Although we haven't seen any feats of movie Drax, I still think Thor and Hulk (alone) can hammer him down as they can/should in the comics. Zoe's comment was completely off as well. The Guardians can beat Cap for sure but let's say Star-Lord, Drax, Gamora, Groot and Rocket Raccoon went up against the Avengers (Cap, Thor, Iron Man, Hulk)? Drax is the only real threat but Hulk would still smash him, Thor would have to be careful to NOT kill Gamora, Cap and Star-Lord is a tricky one as it could go either way with or without weapons, Iron Man could laser Groot, Groot could smother Iron Man's armor, who knows. Rocket Raccoon is just another pain in the ass, Hulk could easily take a second out of beating Drax to smash Rocket. Hulk and Thor are the big-shots here so I hope Zoe and Dave rethink what they said. I hope the Avengers cast responds to this.
