Brock Rumlow

"There are no prisoners with HYDRA. Just order, and order only comes from pain. Are you ready for yours?"

- Rumlow

Brock Rumlow is a highly trained S.H.I.E.L.D. agent who was the team operative of the sub-blackops division known as Strike. He was revealed to be a sleeper agent for HYDRA.

During one operation Rumlow assisted Cap and Black Widow in the recovery of the stolen Zodiac weapon and the apprehension of the terrorists that stole it.

Captain America: The Winter Soldier
Rumlow and the Strike team, accompanied Captain Rogers and agent Romanoff on a mission to the Indian Ocean to rescue a S.H.I.E.L.D's ship the Lemurian Star from the Algerian pirate Georges Batroc. After the mission, Nick Fury became suspicious of Project Insight, which unknown to him was HYDRA's plot to use a fleet of Helicarriers to kill millions of individuals targeted by an algorithm designed by Arnim Zola to select potential threats to global stability. Once the Winter Soldier (apparently) killed Fury, Alexander Pierce, the highest-ranking HYDRA agent within S.H.I.E.L.D, had Rumlow and Strike spearhead the operation to bring in Steve Rogers. However, a surprise attack on Rogers in an elevator at the Triskelion failed, allowing Rogers to get away. Strike were later able to capture Rogers and his comrades Natasha Romanoff and Samuel Wilson after a fight with the Winter Soldier, although the three were again able to escape captivity with the help of Maria Hill. During Rogers' attack on the Insight Helicarriers, Rumlow attempted to stop Natasha and Fury, only to encounter Sam Wilson. The two engaged in a visceral fight, ending in Wilson escaping from a window as a Hellicarrier rammed into the Triskelion, destroying the building. Rumlow was recovered by paramedics, badly burned and wounded.

"You dropped a building on my face!"

- Brock Rumlow

Rumlow had assembled a team and went to Lagos,Nigeria, to the city's Center for Desease Control in order to attain a biological weapon. He was sporting a new suit with many advancements with a new Identity, Crossbones. He was quickly apprehended by Captain America, Black Widow, Sam Wilson, and Scarlet Witch. His team was easily defeated while he made a getaway with the vile containing the weapon and what remained of his men. Knowing that they couldn't escape the Avengers, he sent the vial with his men while he stayed behind. He ambushed Captain America and had the upper hand for most of the fight, using powerful gauntlets to brutally beat him in revenge for mutilating him in the events of Captain America:The Winter soldier. However, Captain America gained the upper hand by destroying his gauntlets and knocking his mask off, revealing his horribly burned face. Rumlow then told Captain America that James "Bucky" Barnes had sent them. Captain America was shocked by this accusation and in the brief moments when he was distracted, Rumlow pulled out a detonator for a suicide bomb vest that he was wearing. He detonated it in an attempt to kill Captain America, but the explosion was held back by Scarlet Witch who attempted to prevent the explosion from harming any civilians by raising him into the sky. However, the bomb detonated next to a building, killing Rumlow and many innocent civilians instantly.
