Powers:

Helmut is a strategic and tactical genius, as well as a brilliant planner and organizer. He also has an impressive scientific and inventive ability. He is a masterful combatant, a world class swordsman and an Olympic-level marksman.

Weapons: Zemo makes use of much of the same devices invented by his father, including particle, formula, and adhesive X, as well as his dad's disintegrator gun and anti-psychic headband. In close-combat, he prefers an Adamantium sword. He also makes use of various energy weapons and mind-control devices.

Origins:

Baron Helmut Zemo is the son of Baron Heinrich Zemo, the master Nazi scientist and enemy of Captain America during World War II. Heinrich brought his son up to believe in the Nazi ideals of a master race, and that only the Zemo line should be ruling the world.

Learning of his father's death, Helmut, now an accomplished scientist and strategist himself, blamed Captain America, and adopted the guise of the Phoenix in order to kill him in revenge. Zemo was defeated, however, falling in a vat of chemicals, horribly disfiguring him. He has since adopted the title Baron Zemo.
