Crossbones

Crossbones is a Neo-Nazi supervillain from Marvel comics who often works as a henchman for the Red Skull, his childhood idol, - as a result he is one of Captain America's more recurring enemies and was infamous for his part in the apparent death of Captain America following the events of the Marvel Civil War.

He is an extremely skilled street fighter and an expert marksman, wielding a powerful, collapsible crossbow as a main weapon, with many other guns, knives, and explosives on his person.

Crossbones has some similarities to Bane, being a muscular thug who wears a mask - however he is much more of a racist than Bane and is loyal to the Red Skull to the end: his name is somewhat of a reference to the popular phrase "skull and crossbones": further solidifying his partnership with the Red Skull and animosity with Captain America.

Captain America: The Winter Soldier
It has been announced that Crossbones will appear in Captain America: The Winter Soldier. Although his role is yet unknown, it can be assumed Crossbones will appear as the main antagonist of the film.
