Every MCU Villain Ranked Weakest To Strongest

Emil Blonsky was originally hired to captured Bruce Banner. A special ops soldier of great renown and skill, Blonsky was no match for Banner or his alter-ego, even with the Super Soldier Serum given to him by General Ross, and he was later injected with some of Banner's blood, which turned him into a monster aptly named Abomination.

As Abomination, Blonsky held all the power of the Hulk - immeasurable physical strength, speed, reflexes, healing factors and agility. He also had spikes piercing his skin, which were able to hurt Hulk, and very nearly bested his opponent before the Hulk got the edge and knocked him out.

There's a possibility we haven't seen the last of Blonsky, but honestly, it would take an awful lot to bring him down a second time.
