For his first Legion adventure written and drawn after being hired by DC, Jim Shooter fleshed out the origin of Sun Boy, a favorite character who had not been featured in a while. He appeared in #342’s “The Legionnaire Who Killed,” and the Computo Two-Parter, but in fairly minor roles, as compared to his early, take-charge appearances. His last real character moment was back during the Starfinger saga.
And Sun Boy’s origin is tied to that of Dr. Regulus, the villain of the piece.
The story begins, traditionally enough, with Superboy arriving at the clubhouse for a meeting—an election, in fact. Invisible Kid is the new Legion leader, a good thing for Lyle Norg, since he has played, up until now, a fairly small part in the Legion’s adventures. Most likely writers had a hard time figuring out what to do with his fairly limited powers.
