James Buchanan “Bucky” Barnes (Gryffindor, 6th Year, Quidditch captain & Chaser, prefect; halfblood – MIA) was Steve Rogers’ best friend. Always the more talented wizard, Bucky was recruited to contribute to war efforts ahead of his friend, but was captured by enemy forces.
As a prisoner, he was subject to similar but different experiments involving superhuman strength and magical amplification. Unfortunately, the full extent of his capabilities were never fully realized by either himself or others. Bucky lost his wand in an ensuing battle, was stunned, and fell to his presumed death in the mountains in 1945.
