Who he is: Emil Blonsky, a.k.a. Abomination
His power: Blonsky received a smaller treatment of the original Super-Soldier Serum that created Captain America, rendering him stronger and faster, as well as more durable. However, after becoming the Abomination, his powers are similar to those of the Hulk, with the added feature of retractable skeletal spikes.
His story: Emil Blonsky was a longtime commando in the Royal Marines of the British Armed Services. His team was recruited by Gen. Thaddeus Ross to hunt and capture Bruce Banner, a.k.a. the Hulk. After his team was taken out by Hulk, Blonsky demands answers, and Ross offers to give him a version of the Super-Soldier Serum treatment that created Captain America. It has a similar effect on Blonsky, but also makes him far more volatile and aggressive, as he loses touch with reality. He eventually makes his way to New York City, where he forces Dr. Samuel Sterns to inject him with Banner’s gamma-irradiated blood, which transforms him into the massive creature known as the Abomination. After an enormous and devastating battle, Hulk is able to defeat Abomination, and the villain is taken into confinement by the American military.
