Ultraman

Trivia

 * Ultraman first appeared in Justice League of America #29 (1964).
 * Superman has noted during a fight with Ultraman that Ultraman constantly murdering his opponents in their first confrontations actually made him weaker than Superman, as he simply eliminated his enemies upon encountering them as they were still getting used to their powers, while Superman fought them as they continued to get stronger and thus had to improve himself, putting Ultraman at a disadvantage when facing Superman's ability to think tactically.
