So some things since, as I’ve been making abundantly apparent, I have quite a few Gotham Rogues in lawful-verse who are immigrants (basically I’m just gonna detail a few nations of origin in my verse):
Jervis Tetch was born and raised in Oxford, England. He moved to the US when he was 26.
Garfield Lynns was born in Wellington, New Zealand, moved to Dunedin, New Zealand when he was 10, and moved to the US when he was 18.
Drury Walker was born in Brisbane, Australia, moved briefly to Jakarta, Indonesia with his mother when he was 4, then moved to Sydney when he turned 5. He moved to the US when he was 19. (as a side note, his mother is Indonesian)
Edward Nygma was born in Kingston, Ontario, moved to Ottawa with his father when he was 11, and ran away to the US when he was 18.
Jack Napier (the Joker) was born in Belfast, North Ireland and was placed with his grandmother in Galway, Ireland when he was 12 after his father died. They both moved to the US when Jack was 16.
Bane, obviously, grew up on the South American Island of Santa Prisca, I’m assuming he moved to the US when he was 19.
