Bowser

Bowser, sometimes known as King Koopa (Japanese: 大魔王クッパ, Daimaō Kuppa, which translates into "Great Demon King Koopa" or "Great Sorcerer King Koopa"), is the leader and most powerful of the Koopas, an evil-driven race of turtle-like creatures. He has repeatedly kidnapped or attempted to kidnap Princess Peach with the ultimate goal of defeating Mario and taking over the Mushroom Kingdom, though he has also attempted to conquer various other realms and even the entire universe.

Appearance
Bowser differs greatly from the rest of the Koopas, who appear mainly as bipedal tortoises. His iconic features include a large, spiked shell, horns, razor-sharp teeth, and a shock of red hair. In addition, while most Koopas appear to be herbivorous and prefer fruits and vegetables as their diet, Bowser, due to his sharp teeth, prefers meat, particularly from victims he hunts down and captures.

Abilities
Bowser has many powers from dark magic that include teleporting, causing shockwaves to come out of his jumps, fire breath, charging, and transforming victims.
