Mister Thomas is a character that appears in the Sonic the Comic series published by Fleetway Editions. He is a human who worked with Miller as Dr. Ivo Robotnik's image consultant onboard the Egg Fortress in the doctor's early days of ruling Mobius.
Thomas is short of stature. He is bald on top of his head, and has thick stubble around his mouth and a black ponytail. For attire, Thomas wears round glasses, a yellow long-sleeved shirt with a white collar, a medium-ling blue tie, grey pinstripe trousers and braces, and brown shoes.
During Robotnik's early rule, Thomas and Miller noticed that the people did not like the dictator and felt he should undergo a complete make-over so that the public might perceive him better. When Thomas and Miller presented their plan to Robotnik however, they were kicked out of his office by the doctor himself (even throwing his phone and lamp at them as they fled), because as a "merciless, power-crazed dictator" he did not care whether people liked him or not. Nevertheless, Robotnik did heed Thomas and Miller's idea and decided that his current body had "served its purpose" and that it was time for a change, leading him to evolve into a new form.
