J.T. (Classic)

J.T. is a bully who first appeared in And Then There Were 10 with his best friend Cash.

Appearance
He has unkept, brown hair and brown eyebrows. He has light blue, round shaped glasses, just like Jamie but it has a silver frames. He has a dark olive shirt and a yellow T-Shirt under that. He wears light olive pants and brown shoes.

In Alien Force and Ultimate Alien, he almost looks the same as his 10-year-old-self. His eyebrows and his glasses' frame are now black. He is wearing an olive T-Shirt and beige pants.

Ben 10
J.T. appeared in The Unnaturals with Cash as a local Little League Baseball player having gotten in as a result of four other members getting chicken pox. Ben decided to use XLR8 to get revenge on Cash and J.T. by making them look bad during the game but later helped the team tying with the Squires. Later in that episode he and Cash were captured by the Squires and nearly killed and replaced with androids but were later saved by Gwen, Max and Diamondhead. He used to be a friend of Ben until he started to hang out with Cash.

Alien Force
J.T. reappeared in Ben 10 Returns: Part 1, when Ben beat his team at soccer. He appeared again in The Gauntlet where he and Cash tried to bully Ben but Ben stood up to Cash which made him very angry. Which also gave him the idea of pushing Kevin's car off a cliff, which they did, after they did it they ran off with the Techadon hand. He later found out it shoots laser in which got the attention of Cash and took it off of J.T., but when the hand started taking over Cash's personality, he went to get help from Ben, during the battle between Ben and Cash he helped Cash regain control of himself.

Ultimate Alien
In Fame, J.T and Cash appeared near the end of the episode applauding Ben of his newly revealed hero status.

J.T. and Cash appeared again in Reflected Glory where they start a blog saying that they're the master minds behind Ben 10 and succeed in convincing Ben, Gwen and Kevin to play along. Everything was going great for them, but when Psyphon showed up trying to destroy them as revenge (one action they took credit for was the defeat of Vilgax during The Final Battle: Part 2) they don't want to be so famous anymore. At the end, even though, they gave up their fame, they suddenly want it back after they saved Ultimate Spidermonkey from Psyphon using a canon blaster, but that, their one and only heroic action, was not filmed and because of their confession earlier no one will listen to them, reducing them to losers who are disgraces to their previous so-called "hero" titles.

Omniverse
In And Then There Were None, J.T. made a cameo appearance in an alternate reality. He was playing soccer just like in Ben 10 Returns: Part 1 but he was on Ben's team this time. It later revealed that he is the best friend of No Watch Ben and was friends with Cash too before he moved to another town.

Trivia

 * According to Gwen in The Gauntlet, J.T. and Ben used to eat paste.
 * According to Gwen, J.T. and Ben were best friends in the first grade before Cash moved to Bellwood.
 * J.T. is only with Cash so Cash doesn't pick on him.
 * In every one of J.T.'s appearances in the original series, he and Cash were suspended from their underwear by Ben. The first time as payback for when they hung Ben from a tree by his underwear earlier in the episode, the second as payback for taking credit for saving the president, and the third just for the fun of it, since Ben's secret had been revealed anyway.
