T.J. Detweiler (Earth-101001)

Theodore Jasper Detweiler (セオドア・ジャスパー・デトウィッター Seodoa Jasupā Detou~ittā) is one of the main protagonists of the TV show Recess and the anime series Kingdom Hearts (2015 TV series).

Appearance
Teej's physical appearance has changed throughout from a nine-year-old to a seventeen-year-old. However, he retains some recurring characteristics. He has light brown hair, green eyes, light skin, and he's quite slender for his age, though he shows average height and weight loss.

Five years later, Teej had grown noticeably taller.

In Recess, T.J.'s usual clothes consisted of a red baseball hat facing backward, a white t-shirt, a green jacket, baggy jeans, and sneakers.

In Kingdom Hearts: 2015, Theodore wore an olive green shirt with grey long sleeves, blue pants, and black and white shoes, but, still kept his backward hat.

Personality
Teej is an outgoing, kindhearted, and friendly person. He also appears to have a good sense of honor, which was demonstrated when he realized how wrong it was to take advantage of Finster while she was injured and when he discovered an envelope with money and decided to give it back to its rightful owner rather than keep or spend it.

Over the years, Teej's personality remained relatively the same as before, although he had matured quite a bit, responsible and sensible. He's willing to sacrifice even his own life for others. Merlin the wizard has praised Teej's good nature, going so far as to say he had the gift to make the right choices at the right moments.

However, when Teej fails to save someone, he becomes angry and much more violent. Perhaps the most notable of these instances is when Kevin willingly mutated himself to succeed where Marcus is not strong enough to stop Tobio, Teej was set on killing Kevin, even fighting Celia when she refused to help him.

Later on, Teej starts thinking of himself as more of a superhero than a crime-fighter, although he once again became cocky, he retained his selfless and heroic nature.

Teej's Parents
His parents are very loving and supportive. They don't always appreciate the full extent of T.J's high spirits, but they love him just the same.

Becky Detweiler
Teej's relationship with his sister Becky is on much shakier ground, but underneath all her objections she does love him too, even coming to his rescue in Recess: School's Out.

Mikey Blumberg
Teej is good friends with Mikey. Teej. says he "appreciates his insane (innate) spiritual gifts". However, he is sometimes embarrassed by Mikey's behavior. After Mikey read a poem inspired by Menlo, Teej claimed, "for once, it didn't embarrass me" but, Teej respects Mikey despite his behavior.

Gretchen Grundler
Teej surprisingly doesn't say much about Gretchen. She has, apparently, tutored him in Grammar. The two don't always see eye-to-eye on things. T.J. supported her in her math club with Hank but soon stopped going since it put the gang to sleep. Gretchen didn't consider T.J. a friend for a while since he didn't share her interest in science and astronomy, or helped make her pinhole projector. In the end, they apologize for taking each other for granted. Teej respects her and Gretchen says he is a good friend.

Vince LaSalle
Many have speculated Vince and T.J. to be best friends. Vince and T.J. act as characters from their favorite book. They are seen doing a lot of things together back in second grade, such as being in the same Boy Scout troop or making up the word "Whomps". However, T.J. can't quite bring himself to say Vince is his best friend, though it is implied that this may indeed be true due to the length of this particular scene when compared to the other members of the group. Vince is also occasionally ambivalent to T.J.'s plans. It is thought T.J. shares the most interests with Vince, but he is an equal friend in T.J.'s sight.
