Intro. Helmut first surfaced under the alias of the Phoenix, and captured Captain America to get revenge upon him for the death of his father. He was presumed deceased when he fell into a vat of boiling, specially-treated Adhesive X (a chemical created by his father Heinrich, which was a universal adhesive and was practically indissolvable). in a dramatic echo, Helmut's face was hideously scarred by the boiling Adhesive X, giving his face the appearance of molten wax. Fighting Captain America and Diamondback, Zemo's plan backfired, as he instead turned his father's corpse into a vessel for the demonic forces that lurk inside of the Bloodstone. The reanimated corpse was destroyed by Crossbones (who sought to steal the Bloodstone for Red Skull) and a distraught Zemo fell down an inactive volcano in Japan trying to retrieve it.Zemo survived the fall, though his right hand (which was not protected by a glove) was horrifically burnt and mangled.
