Bowser is a villainous koopa and an atagonist of the Dark Storm series. His home world is Mushroom Kingdom, but he lives in Bowser Castle.

Dark Storm
Bowser is second-in-command to Chad Endy. He is fought on the following worlds: Jublife City, Mushroom Kingdom, Bikini Bottom (with King Jellyfish), and Hollow Pokemone. He is a recurring (and annoying in creator Stephen Lippincott's opinion) villain. He disappears after being defeated at Hollow Pokemone. It is suspected he hides in the sewer system the rest of the game.

Dark Storm 2
Bowser is now still second-in-command, this time serving under Fawful. He is fought at: Jublife City, Mushroom Kingdom, Black Earth X, and Fawful's World. He is beaten at Fawful's World, and then he alerts Fawful about Stephen before teleporting to an unknown world. In a future game, the player might find the world where Bowser's hiding.

Dark Storm 3
Bowser will not be the leader, and will serve under High Roller.

Trivia

 * Bowser's Castle is a mini-world
 * The world he disappears to post-DS2 might be Big Green
 * His best O.O.V.A.L friend is probably Herbert P. Bear. Both are mean, both are not human, and both can control Darkness like puppets.
