Jonah

Jonah is an alien who survives by moving from body to body. Decades ago he took a Melbourne doctor's body, which is why the man dies speaking with an Australian accent. He helped Leslie Dean's father found the Church of Gibborim, bankrolled the Pride, and kept himself alive on the sacrifices they made. He is Karolina's biological father. Nico killed his host, but he and his family took over the Pride parents' bodies, until Nico made them all vanish with the Staff of One.

First turns up in Runaways (Season 1).
