Niles Caulder (Earth-9107)

Dr. Niles Caulder, alias the Chief is a paraplegic gifted with a genius-level intellect. Caulder uses his scientific knowledge to develop numerous inventions and innovations that have made him wealthy. Caulder founded and organized the team called the Doom Patrol to protect the innocent and fight crime, and to teach humanity to accept others who live as ostracised "freaks," who have been radically transformed from terrible accidents. It is Caulder's genius that allowed the team members to survive (e.g., designing Robotman's body, devising Negative Man's medicated bandages), and helping to develop their amazing abilities.

However, he has a dark side: He was the one that caused the accidents that created the Doom Patrol, psychologically abuses them (Especially younger heroes like Beast Boy), and even threatened some of them to take away their "Gifts" (Such as Robotman's body).
