2. Hulk One-Punches A Space Whale (The Avengers)
The most bad-ass of all these strength feats comes from the Hulk. After fighting with Thor on SHIELD's hellicarrier, Bruce Banner fell to Earth and ended up away from the rest of the Avengers. When New York found itself under attack, he was nowhere to be seen. The other Avengers were left to deal with the vast Chitauri ground forces and giant space whale creatures without him. However, Banner arrived on a moped as one of the giant creatures approaches (Iron Man having "brought the party" back to the rest of his team). Whilst Banner walks towards it, Captain America advises him that "now might be a good time to get angry". Banner responds with "that's my secret Cap... I'm always angry" and proceeds to immobilise the massive, armoured creature with a single punch. Given the size of the creature, just stopping it would've been impressive, but the fact he outright killed it was awesome.
