Captain Shields

Captain Logan Shields is a high-ranking officer in the GPU (Global Protect Unit). He serves as the lead officer for the GPU's main branch in Starview Heights, and also serves as the mentor to the Spy-Busters.

He lives in an apartment that he shares with Colin and Colleen, who he is the legal guardian of and has been ever since their mother died; he also has a daughter, Sonia, but she is currently in Los Angeles working as a teen pop star. He also used to have a wife, but she died a long time ago due to circumstances that have yet to be explained.

A stoic man who guides the Rangers with a loving yet stern hand, he is very sentimental, and sees Colin and Colleen as his children despite not being their biological father. He cares for all of his Rangers deeply, and will do anything to protect them from harm.
