Bowser

Bowser is a large, dragon-like Koopa, which is a race of turtle-like beings. He has large lips with sharp teeth, yellow and green scales, lines on his stomach, and sharp claws. His most recognizable features are his spiked shell, red mane, horns and spiked cuffs. Bowser is an extremely sadistic and cruel tyrant, who will goes to great measures when it comes to getting what he wants and doesn't hesitate to destroy anyone who gets in his way. He also went as far as attempting to burn all of his prisoners alive (one of them, Lumalee, being a child) in lava for no legitimate reason during his wedding with Peach, saying that he was doing it in "her honor" even though she was obviously horrified by it. According to the princess herself, Bowser is immensely deranged and psychotic. He cares for the well-being and lives of his minions. Bowser himself admits that he is aware that the princess hates him, but claims that it makes him love you even more. He is also deeply paranoid and insecure, as, despite saying otherwise when Kamek says he shouldn't be worried, he immediately felt threatened by Mario when learning that Peach was training him, feeling that the plumber could be a supposed rival for your affection.
