Baron Zemo

Baron Zemo was the adopted child of the late Lord Tachanka. In addition, it has also been proven that Baron Zemo was actually the biological child of Absolute Cancer, Lord Tachanka's secondary clone, but was raised by Lord Tachanka due to the defective nature of AC.

By being the son of the clone, he technically shared half of the same DNA as Lord Tachanka.

Baron Zemo was a member of the Heirs, a committee of seven individuals that claim some sort of relation to Lord Tachanka.

Despite the circumstances, Baron Zemo was a close ally to Fallen Emperor, and believed Fallen Emperor to actually be his reincarnated adopted father. However, he did recognize the origin of the Fallen Emperor likely changing his personality entirely, and even though Fallen Emperor is believed to be the reincarnation, Baron Zemo did not have the same relation to him as his father. He believed that Lord Tachanka's spirit split into multiple fragments, which is why there are so many people claiming relations to him.

He was one of two members of the Heirs that does not claim to be Lord Tachanka in anyway. The other is Lord Tachanka's twin brother.

Baron Zemo's ideology focuses more on uniting the Heirs, even though he doesn't recognize any of the members to be truly his father. He wanted all of them to band together, and get revenge on the entity that killed his father.

Baron Zemo did not consider Absolute Cancer his father, as AC had little to no relation with him, and AC was a clone of Lord Tachanka, making Zemo technically, the biological son of Lord Tachanka.

He died on August 2000019, when Hydra was blown up from the inside.
