Is Bowser Gay or Bisexual?

Great question! Originally, when we envisioned the character of Bowser, we imagined a love triangle between Mario, Peach, and Bowser with romantic tension existing between all three characters (as you can clearly see in Super Mario Odyssey). However, when Super Mario 64 came out in 1996, we wanted to be more obvious about the hidden relationship between the red-suited plumber and King Koopa, so we inserted the subtle line “So long, Gay Bowser” where his interest in Mario was revealed (hidden under layers of friendly rivalry and “enemies to lovers” tropes). Over the years and generations of games, society’s views on sexual orientation has changed, and we finally felt like being more open with Bowser’s true orientation was acceptable. You can see this reflected in the line “Bye Bi,” which we included in the 2020 re-release of Super Mario 64. But, at the end of the day, Bowser’s sexuality is fluid, and his identification changed over time. For now, we can officially confirm that Bowser is bisexual.
