Alternative names: Stellar Bowser, テラクッパ

A monstrous fusion of Bowser (the dominant fusee) and Terapagos in Stellar Form since they’re both tough turtles. 18 Types squall, 18 feet tall (100.3 meters in full power), yet much more mobile than he seems at all. So yeah, this guy is a real king of gems. And this is not the same Bowser from the games, it’s the one from the 2023 movie, who is much crueler and has complete control over the body. By the way, this fusion holds several references/similarities to Bowser’s other forms, in addition to altered colors:

• Like Dreamy Bowser, TeraBowser has stones on his forehead and abdomen.
• Like MegaDragonBowser and Fury Bowser, he has a longer tail and blank eyes.

** His spike rings and limbs are visually modified like for the former.
** His body is also proportionally larger than his head, like for the latter.

• Like in Paper Mario Sticker Star, he wears a crown and parts of his body have a gem texture.
• Like Giga Bowser, his shell, horns, and hair are wilder in style.
• The tail tuft and legs bring a feline-like feel akin to Meowser, though to a limited extent.

However, TeraBowser is likely more powerful than all of the above, so these are their stats, a total of 785!
