Dr. Theo

Dr. Theo is a supporting character in the series GANGSTA.

Background
Dr. Theo is the man who is teaching Nina how to be a nurse. He usually treats Worick and Nicolas' wounds when they come by and gives Nicolas medication. He has apparently known the duo for a long time, having shown to have met them when all three men were still young children, possibly even right after Nicolas and Worick came to Ergastulum.

He is first shown being bothered by a group of thugs, one of which is a Twilight, and sends Nina out to get Nic for him. Though he wasn't bothered by the fight between the two, he was bothered once his precious shop was damaged and even tried to "kill" Nic afterwards with one of the many needles he holds in his jacket.

Personality
Initionally calm and collected, Dr. Theo can become irritable if something happens to his shop.
