Trivia: Smash King
- Mythology Gag: This one is arguable, but the voice that Tigura21 uses for Bowser is somewhat based on Bowser's voice from The Super Mario Bros. Super Show.
- What Could Have Been: Apparently, Tigura originally planned Marth to be the third teammate rather than Meta-Knight, but decided that having two human characters with Bowser in on team looked off
- Marth was also originally planned to be the third member of team Sonic but was replaced by Ike after Tigura21 decided to expand on Ike's role
- Even bigger was the original premise. Smash King was meant to be a sappy romance story between Bowser and Peach, before several revisions turned it into what it is today, even though some bits from the original plot made it into the final draft.
- An alternate version of Peach's charging of the Peach beam was recorded not by her usual actress Megami33, but rather by Zelda's actress Kira Buckland.
