Adventure Comics #260 (May, 1959)
Title: "The Kents' Second Super-Son!"
Writer: Otto Binder
Penciller and Inker: John Sikela
Cover: Curt Swan & Stan Kaye
Editor: Mort Weisinger
I decided to follow up on my post about the United Planets Superwatch from The Green Lantern by doing reviews and analysis on the first appearances of every individual member. Unfortunately, none of them had features in the Legion's Who's Who series, so I thought this'd be a good way to talk about the UPS's line-up.
I planned to start the series with Vidal but due to the bugs after the blog was updated the draft kept freezing. Thankfully it seems to have gone back to normal so I can finish this uninterrupted. Vidal, alias Alan Greene, originated as one of many superpowered boy heroes who graced the pages of the Silver Age Superboy comics. While his debut (and only appearance) originated from Adventure Comics #260, I read about him in the reprinted version from Superboy #129 (which also featured Superboy meeting Mon-El and Supergirl).
The story initially sets up the idea of Vidal acting as Ma and Pa Kent's replacement for Superboy as their son. Actually, the story's a study in tension as the Kents fear Vidal's people have done something horrible to their boy!
