Melvinborg is the main antagonist of the second season of The Epic Tales of Captain Underpants. He was the future version of Melvin Sneedly and the former principal of Jerome Horwitz Elementary School, which he renamed Melvin Sneedly Elementary School in season 2. Before the Bizarre Blitzkrieg of the Bothersome Butterflies episode, Melvinborg was known to be good. However, the attack by the butterflies drastically changed him, and he became the one you see in our fanart Captain Underpants Melvinborg cursor.
