Seems there was another crime fighter called the Red Hood, but not from DC, in 1941 there was a very short lived pulp magazine called Red Mask Detective Stories that lasted for two issues and then was changed to Red Hood Detective Stories for one issue.
I have no details about the Red Hood found therein other than “Most of the stories were sluggish trivialities by obscure writers about a two-fisted crime buster names Perry Morgan who sometimes put on a red hood to do that busting.”
Forgotten genre, or sub-genre I guess, it seems that there have been at least four comic book series, some running for over 30 issues (better than most of DC’s `Forth-World’ characters can do) based on the adventures of horses, Black Fury from Charlton even featured early art by Steve Ditko. .
Usually the horse of a famous B-Western film star, but in the comic it’s all them without the cowboy hero ever showing up with the entire dialog being supplied either by characters unique to the horse in question adventures with without dialog and just a bit of descriptive text above the action.
Shows what you could get away with when comics were plentiful mostly ignored and cost only a dime.
