Power Girl.
In this AU Kara was taken in by Jonn as his apprentice to become a cosmic protector. She hasn't met Clark at this point and still believes to be the last kryptonian alive so she feels like its her responsability to rise as the newest beacon of hope in the universe.
GL: MARTIAN MANHUNTER.
J'onn J'onzz has been functioning as the universe's most powerful protector way before the Kryptonian appeared. Anti-social and reserved; he doesn't trust the Guardians and their lanterns for his own reasons, so the Guardians agreed to leave him alone.
