Brock Rumlow (Earth-11584)

History
"'I should torture you to find Barton's wife Stark, make her pay for the redecoration stunt she pulled on my face. Or maybe I'll just pay it forward by rearranging yours!'"Coming Soon...

Powers & Abilities

 * SHIELD training: Like all SHIELD special agents, Rumlow received basic training in firearms and unarmed combat, though Rumlow's training was likely far more advanced since he led a Special Ops Team known as STRIKE in combination with Capt. Steve Rogers.
 * Pneumatic Gauntlets: Since the fall of HYDRA, Rumlow has operated as a freelance mercenary, and began using pneumatic gauntlets to augment his physical strength tenfold. The gauntlets use pressurized air to increase the power of his punches, and have been shown to be able to destroy solid brick walls with a single blow.

Weaknesses
The pneumatic gauntlets that Crossbones uses do not appear to be top of the line made compared to other advanced tech we have seen, as they are prone to breakdown at inopportune time. Despite their strength, as well, Iron Man has shown that he can take a full on punch from them and still survive relatively unscathed, so there effectiveness against high-end enemies is suspect.

Film Details
Rumlow appears in the following films in the Earth-11584 continuity. In all cases he is portrayed by actor Frank Grillo.
 * Captain America: The Winter Soldier (2014)
 * Iron Man 4 (2016)
