Doctor Ivo Kintobor (Pre-SGW)

Kindly Veteranarian
Anti Robotnik ran a veterinarian clinic to heal and protect various Mobians who had been attacked by the Anti Freedom Fighters. To protect his clinic, he employed a dome force field to keep the Anti Freedom Fighters out. Additionally, Anti Robotnik employed SWEEPbots to clean up litter left behind by the Anti Freedom Fighters.

When he first encountered Sonic the Hedgehog, Anti Robotnik mistook him for his Anti Mobius counterpart, Anti Sonic and ordered his patients to capture him. However, he soon realized Sonic's good intentions after he assisted in defeating Anti Sonic. Anti Robotnik then gave Sonic Prime a device to clean up all the waste Robotnik Prime was pooring out of one of his factories back on Mobius, and it did its job so fast that it caused the factory to explode under pressure.

Helping Sonic and Amy
Years later, Anti-Robotnik (now going by the name Dr. Ivo Kintobor) once again encountered Sonic Prime when he and Amy Rose journeyed to Moebius in order to find assistance against Scourge and his Suppression Squad. Calling off Buns Rabbot from her attack, Anti Robotnik explained to her the two weren't enemies. He then proceeded to explain how he'd constructed the Omega Care Unit to prevent Buns's Neuro-Immuno Deficiency Syndrome (NIDS) from spreading throughout her body, and that the Suppression Squad had stolen his Globe Posts, which he'd created to travel to other zones to find new medical techniques to help cure NIDS. Asking him for help, Sonic and Amy were later directed by Buns to seek out Anti Amy to defeat the Suppression Squad, though Anti Robotnik objected to this due to her insanity. However, he later allowed Buns to accompany Sonic and Amy in their attempt to recruit Rosy, though he continued to worry about Buns's safety.

Following the successful defeat of Scourge, Anti Robotnik's Globe Posts were returned to him by the Suppression Squad under Buns's watch. As the Freedom Fighters returned to Mobius Prime, he personally thanked Sonic for his help and then transported him to the No Zone where Scourge would be imprisoned by the Zone Cops.
