Dr. Calgary

Dr. Calgary is a surgeon that Steve visits on the advice of Klaus to become taller in "Roots". At the doctor's, a sudden change in his personality occurs upon hearing Klaus' name, offering a surgical solution and Steve decides to think things over.

Although he elected to have the surgery after thinking it over, Steve starts to have second thoughts after meeting the doctor's creation, Billy, but is knocked out before he can get away. Due to Stan's smashing of the building with a wrecking crane, he faces being dropped from the remains of the building until he is saved by Stan. As the police approach, Dr. Calgary instructs Billy to fly away. But as two large metal wings sprout from his back, he drops backwards from the weight onto the floor.

Dr. Calgary becomes Roger's physician in "Roger's Baby" when he attends to the rebirth of Jeff.
