The Western craze continues with the introduction of a new Western character with an old name in All-American Comics #100 (June 1948): Johnny Thunder! Yes, just six months since Johnny Thunder disappeared from DC comics, a completely new character steps in and takes over his name. Johnny Thunder is a blonde school teacher who has a secret identity as a black-haired adventurer. Johnny Thunder also heralds the ending of All-American as a superhero comic: In just three more issues, All-American Comics would become All-American Western.
Funny side note: this Johnny Thunder has a horse for a side kick named Black Lightning. Another well-known DC name with an obscure origin!
