Theodore Jasper "T.J." Detweiler is the main protagonist of Green Rangers. He is the ringleader of the destructive six who he spends most of his time with. TJ is known for his sense of rightiousness, justice and the ability to make a plan that will ensure days in Harlowton are smog free.
He was once a member of The Dominion, which was a circle of friends at Harlowtown High School. They were heavily involved with the Light Industrialist Cause, and he was ousted when he became angry when they started talking about the new mall, and his head turned into a melon.
