Bowser the evil king of Koopas. He has been trying to take over the Mushroom Kingdom for years and he tries to do that by kidnapping and forcibly marry the princess who he is also in love with.
Bowser might look like just a brute but he has great leadership skills and comes up with a lot of evil plans. He is cruel,self centered,and has a huge ego. He also doesn't have much common sense like when he breathed fire on a bomb. The only people he shows emotion towards is his kids the Koopalings. And Princess Peach who he loves very much.
Bowser has amazing strength but his signature move is his ability to breath fire.
