 When Superman expressed some concern that Red King (1) possessed too much power for any one person, Green Lantern (John Stewart), stated that Red King (1) 
“probably wouldn’t even bother” 
working with the League if it wasn’t for Wonder Woman.The Martian Manhunter stated that he couldn’t read Red King's mind, but Red King (1) genuinely seemed to care for Wonder Woman and she trusted him, so they decided they should trust him as well.This Parallel's League soon learned of the truth behind the Red King (1) when Batman learned the comatose Doctor Destiny had been repeating his name over and over; Dee then awakened and told him the truth about the Parallels, and ultimately the JLA attacked Profitt.
