CROSSOVER MADNESS

 This one might top the last post, though. First, in a COMEDY COMICS strip called THE VAGABOND-- formerly a Timely costumed hero, but one converted into an average goofball-- the protagonist met an equally goofy villain, the Creeper.

Then someone decided that a KRAZY KOMICS feature about a rabbit-detective named Homer needed a shot in the arm, so they transferred the Creeper over there and retitled the feature THE CREEPER AND HOMER-- though even I am not interested as to how long that state of affairs persisted.
