One of the many golden-age characters to make a cameo in PROJECT: SUPERPOWERS #0 was Boy King (along with his "sidekick" Giant). But who is/was Boy King?
Well, we'll get a clue from his origin story printed in CLUE COMICS #1 (January 1943). Page 2 of the story proclaims that "the people of Swisslakia were light-hearted and gay..." And you may think that gay is used as a colloquialism of the day. But when you get to page 11 and see the attention to detail that went into the Giant's, um...below-the-belt region...you may start to suspect otherwise. Enjoy!
