10 Most Powerful Characters Killed By Captain America

10. The Colonel - The Ultimates Vol. 2 #12

The Ultimates line of comics serve as an interesting time-capsule of sorts, capturing Marvel's rough yet inspired attempt to place its characters in the modern-day in the early 2000s. While this did not always resonate with fans, it served as a fascinating counterpart to the then-main, Earth-616 timeline.

During the first run of the second volume of the Ultimates, the eponymous team (this universe's Avengers) was tasked by the U.S. government to conduct pre-emptive strikes on Global South nations to dismantle their weapons program.

Naturally, this triggered the affected nations to develop their own superhuman team known as the Liberators and chief among them was the Colonel, Azerbaijan's answer to Captain America. Once a scrawny teenager, Abdul Al-Rahmani became the second person to be enhanced by the Super Soldier Serum after Steve Rogers himself.

The Liberators went up against their American counterparts and the two super-soldiers engaged in battle, with Al Rahman eventually losing his hands due to the Hulk's intervention. This gave Cap the chance to overwhelm his opponent and stab him with his own weapon, killing the Colonel instantly.
