A wiki page for collecting miscellaneous Ultraman trivia, records, and noteworthy firsts.
Things to add
- First series with a combining plane? Note: Not a big plane that splits up. Something like Nexus' Chrome Chesters combining into one.
- First Ultraman host whose identity is known to others (not kept a secret)?
- First Ultraman who can summon a shield? (Ace has a shield for example)
- First series with the death of a defense team member? Was Leo the first?
- First Ultraman host to reveal his identity to a human? Notes: Ultraman / Shin Hayata was a human host, while Dan Moroboshi is an alien, UltraSeven himself. However, Shin Hayata never revealed himself to a human to be the host of Ultraman in the series. A good example would be Ultraman Tiga / Daigo who let Rena know about his identity.
