In an alternate timeline in which Doctor Robotnik had never been created and the Brotherhood of Metallix had taken over Mobius, Rob was the assistant of Doctor Ovi Kintobor, who in this reality was the leader of the Underground, the last living people on the planet. Rob was with Kintobor when he rescued the original timeline's Sonic the Hedgehog, Porker Lewis and Chaotix from a Metallix patrol. In particular, Rob set up a hologram of the heroes, luring the pursuing Metallixes into a trap and then destroying them with a bomb.
