TW: mentions of death and child abuse ahead!
Rotor the Walrus was the oldest son to Tundra and Snow the Walrus, born within the arctic regions of the planet. While Rotor was still very young, Snow had fallen extremely ill and later died from the illness. An inventive child, he would often tinker and make new gadgets out of whatever he could find, much to the anger of his father, who had a strong dislike of anything new or different, not to mention a general dislike of Rotor himself.
Tired of his life, Rotor decided to leave his home and make his way south to the “greatest city in the world”: Mobotropolis. Unfortunately for the young walrus, he arrived in the city smack bang in the middle of Dr. Eggman’s takeover. However, he managed to find his way to Knothole Village where the exiled were hiding. It was here where he became a member of Princess Sally’s band of Freedom Fighters, using his technological know-how to create gadgets and traps for use on the field. The tinkerer quickly bloomed into a full-blown inventor.
