The son of the original supervillain Baron Zemo in a long line of royalty, Helmut Zemo took up his father's legacy and became a modern version of the infamous super-Nazi.
Wanting revenge on Captain America for his father's death, Helmut first took on the guise of the supervillain Phoenix (not to be confused with Jean Grey aka Dark Phoenix) but was defeated and fell into a vat of chemicals, disfiguring his face. He later appeared as the next Baron Zemo, and lead a new version of the Masters of Evil, defeating the Avengers and taking over the Avengers Mansion before being overpowered by Captain America. He battled the Captain and the Avengers several other times after.
When the monster Onslaught seemingly killed Captain America and the Avengers, Zemo was distraught, as he saw his life was now meaningless without an archenemy. He then decided to form a team of supervillains and masquerade as heroes in hopes to gain the trust of the public. He took the name Citizen V and called his new team the Thunderbolts. His plan succeeded and everyone believed that the Thunderbolts were heroes. When he finally gained enough resources and actually took over the world, the rest of his team turned on him and mutinied because they had actually enjoyed being good.
Zemo had many later run-ins with Captain America, the Avengers, and the now-good Thunderbolts. After awhile, Helmut began rethinking his villainous lifestyle and became more of a neutral character.
