Jack Spicer

Jack Spicer is the main antagonist of the 2003 show Xiaolin Showdown and its 2013 reboot/continuation Xiaolin Chrinonicles. In both Jack Spicer is a teen genius with an adoration for evil and a desire to rule the world, teaming up with other main antagonists such as Ms./co/ competitor, Wuya, and Chase Young. He is gifted in robotics, mechanics, and other technology, with major feats such as building a working time machine (albeit one that requires enormous amounts of energy, so much that he can't produce enough to go more than 5 seconds backwards or forwards with a normal power grid.) and also creating armies of robots that serve various purposes from offense, espionage, or household tasks. He has even created a robotic double of himself on multiple occasions.

Jack Spicer himself is notable for being a contestant in every single Mr. /co/ competition so far (2018, 2019, and 2020). However, he has never made it past round two despite his luck in qualifying. His most notable match ups so far are against Elite 8 Member Aku in 2018, Elite Member Hank Hill in 2019, and Godzilla in 2020, where he had just lost against the kaiju by 10 votes in his closest shot to getting past the 2nd round. Jack Spicer's crowining achievement however is kicking out the much higher seeded competitor, Steven Universe, in 2019.
