Royal Roy began in April 1985 as an answer to the successful Harvey Comics Richie Rich series.

Its title character was the young Prince Roy of Cashelot, a fictional kingdom whose name was a portmanteau of "cash" and "Camelot".

Also like Richie, Roy had a sweet-natured middle-class girlfriend (Crystal Cleer) and a wealthy, abrasive acquaintance (Lorna Loot) who vied for his affections.

In late 1985, Harvey Comics sued Marvel for copyright infringement, claiming that Royal Roy was a blatant copy of Richie Rich.

An updated version of Royal Roy (along with Planet Terry, Top Dog, and Wally the Wizard) is featured in the four-issue X-Babies miniseries published by Marvel Comics in late 2009.
