Jimmy Kent, or Jor-Zod, is the son of Kara Zor-El (Linda Lang) and Lor-Zod (Christopher Kent). He was born on New Krypton in 2018. His parents never married, but remain amicable. He's been raised mostly on New Krypton, but spends time on Earth with his mother, who is the ambassador between the two planets. His father is a member of New Krypton's high council, along with his adopted grandfather, Kal-El.
Because of his father's Phanton-Zone-affected physiology, Jimmy grew rapidly at first. Bart Allen, having gone through something similar himself, helped to slow his aging rate down, but Jimmy's physical body appears about two or three ears older than he his mentally.
Jimmy calls himself Superboy, but his parents say he's too young to be a superhero just yet, despite his rapid aging.

Jimmy's PB is Max Thieriot.
