Jack being an obvious parody of DC's Martian Manhunter, The Boys' series developer Eric Kripke has shot down an appearance by Jack, wanting to keep it grounded without alluding to Alien origins suggested by Jack's appearance. Kripke is in the right to keep with the grounded approach as it's seen obvious success in adaptation. With that being said, fans still want to see Jack from Jupiter, and consider Kripke's concerns to keep it grounded, I have a few ideas to adapt Jack without breaking the grounded theme of the show. These are my ideas on how to develop Jack from Jupiter for The Boys.
