Winter Soldier is a badass

The man – or whatever the fuck he was – had slaughtered his way through 1 American President, 12 other Muggle Heads of State, 16 Generals of varying armed forces, 70 other military officers, 213 police men – counterparts of the Department of Magical Law Enforcement, or so Lucius gathered – of all ranks, 79 general bodyguards, 9 Ministers of Magic, 16 Auror Commanders, 147 Aurors, 2 Directors of SHIELD, 5 Deputy Directors, 89 SHIELD/SSR Agents, 43 Agents of MI6 and MI5, 22 Agents of MI13, 200 members of other security agencies and at least 500 other miscellaneous targets.

Among the higher echelons of the Security Services, he was also suspected of involvement in the Lockerbie bombing, direct or indirect, and training anti-Western paramilitaries. Some IRA bombings and assassinations carried his distinctive stamp, and the assassination of Lord Mountbatten and the attempted assassination of Prime Minister Thatcher were two he was mainly suspected of.

However, he was apparently not guilty of the latter by simple dint of the fact that the woman in question survived. This spoke volumes of how dangerous he was and how he was regarded by his enemies.

He also had a record of excellent performance against superheroes: the first Spitfire had died at his hand, leaving nothing but ash and scorched weaponry behind, Weapon X – though apparently unkillable – had been left a shattered mess under the main complex of the Weapons Plus program, which specialised in superhuman assassins. Dyna-Mite and Union Jack a.k.a. Brian Falsworth, son of Montgomery Falsworth, were two other superhero victims of the Soldier.

This last was especially remarkable as Union Jack had possessed the Mantle of Albion, channelled through the Amulet of Right, granting him powers that at their fullest extent, Lucius estimated to be a match for Thor.

Yet the Soldier had killed him. He had killed them all. The first Spitfire was the only one who had ever come close to killing him, and she had apparently been close to unstoppable with a sword. The second Spitfire had apparently escaped with her life on encountering the Soldier, and only done so through a mix of luck and incredible speed.
