Rotor Walrus is a character that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. He is a possible future version of Rotor Walrus from the version of Mobius that Nicole came from.
He is Nicole's creator at the request of Sally, and programmed her with vital information about Mobius intended to help the Knothole Freedom Fighters. He also built in a special firewall that prevents his younger counterpart from accessing files regarding Nicole's origins. This was demonstrated when Rotor, giving up on his efforts to penetrate Nicole's programming, asked her if she was happy, to which she replied "No, but you'd be." (StH: #119, IYF)
