Tiny R is an alternate counterpart of Rotor Walrus from the Sentai Zone. He, and the rest of the Sonicaman: Chaos Ninja Team, were summoned to Mobius Prime by Zonic to save Sonic from Sallactor's attacks. (SSS: #12)
- This version of Rotor is a parody of Ryu the Owl from the Japanese superheroes team, Gatchaman.
- Tiny R is the only member of the Chaos Ninja Team to be the counterpart of an SatAM character rather than a Sega character, and he and Sallactor are the only known inhabitants of the Sentai Zone to possess this origin.
