Abomination (Emil Blonsky)

Abomination used to be a HulkBuster, but was irradiated into a Hulk, and is an enemy of The Agents of SMASH.

Origins
Emil Blonsky was a loyal soldier of Russian descent who was assigned to the Hulkbusters, an elite unit under the command of General Thaddeus "Thunderbolt" Ross. When Emil's combat experience proved ineffective against the Hulk, Ross exposed him to gamma radiation that transformed Emil into a hulking monster dubbed "The Abomination" and set him on the Hulk like a dog. After Hulk had defeated Abomination, Thunderbolt Ross realized Abomination was too dangerous and unstable to be left active, and trapped him in a stasis capsule which was placed at the bottom of the ocean.

Agents of SMASH
Some years later, Abomination escaped and infiltrated the Agents of S.M.A.S.H.'s base to get his revenge on Hulk and Thunderbolt Ross where he tranquilized Skaar, She-Hulk, and Devil Dinosaur and even defeated A-Bomb, using some special goggles that can detect A-Bomb's invisibility. Then Abomination activated a gamma bomb and even a rocket that he would use to get away. During Hulk's fight with Abomination, Red Hulk placed the Gamma Bomb into the rocket. After Abomination knocks Hulk and Red Hulk from the rocket, he discovers too later that the gamma bomb he activated is on the rocket. Following the explosion in the sky, Red Hulk states to the Agents of S.M.A.S.H. that it was unlikely that Abomination perished in the explosion.
