||JOnn indicates that he revealed himself to the Legionnaires, indicating that he was hiding in another guise, perhaps one already known to the Legion. An obvious answer there is R.J. Brande, whose mysterious past is hinted at in Legion of Super-Heroes: Secret Files #2, who revealed strong telepathic powers in Legionnaires #51, and who the creative team admitted was intended to be a cover identity for an unspecified other person (although the story was never told, due to a change of creative teams). However, JOnn JOnzz appears in Legion: Science Police #2 and Martian Manhunter #11, probably precluding any connection to Brande.
|While JOnn refers to dealing with the Legion of Super-Heroes in the next millennium (the one after his 20th/21st century adventures), no year is given. The three presumed Legionnaires pictured cannot be firmly identified; the two face down ones appear to be Cosmic Boy and Saturn Girl, but the costume designs do not quite match the current outfits. (As just the simplest examples, these could be Pol Krinn and Jancel Ardeen, five or ten years down the line.) Also, the lack of specificity of time means that the image displayed here may not be directly connected to when JOnn revealed himself to the Legionnaires; it could occur at some later time.
