History Characters / XiaolinShowdownTheHeylin

* InferioritySuperiorityComplex: For all his talk, the "Truth-Or-Lie" Xiaolin Showdown reveals that he wants to take over the world because he feels small and worthless.

* TeensAreMonsters: Downplayed in that he does have a good side he doesn't want to acknowledge, but he is still a teenager trying to take over the world.

* IncestSubtext: [[spoiler: Shadow was born and created directly from Chase's body after he tore out one of his own ribs which transformed into a baby Shadow which grew into her current form. None of this stops her from flirting with Chase, wanting to be his Queen, and becoming jealous over his affections. She even partially lampshaded the trope when she joked how calling him "Papa" hardly seemed appropriate.]]

* GeniusDitz: He's not exactly sharp but he is brilliant.

* ChildProdigy: He's immature and around the same age as the monks but is a brilliant inventor and engineer. He is never seen going to school but given his IQ, it is very likely he skipped a couple of grades.

* ChildProdigy: He's immature but a brilliant inventor and engineer. He is never seen going to school but given his IQ, it is possible he skipped a number of grades.

** DoesNotLikeShoes: When a humanoid she is always barefoot, possibly to signal her ElementalPowers.

* DoesNotLikeShoes: When in human form, she prefers to walk around barefoot. Overlaps with MagicalBarefooter and UndeadBarefooter.

* WhosLaughingNow: [[spoiler:In the first part of the series finale, his BadFuture self has managed to obtain world domination without Omi to hinder his plans. He spends his days mocking the Xiaolin Warriors by forcing them to fight his robot animals and mocking his Heylin competitors by chaining a depowered Wuya to the wall, keeping an oversized Hannibal in a cage, and hanging Chase by his hands and ankles over a paintbrush that continually rubs yellow paint onto his stomach. None of them really respect him despite his victory, however.]]

** [[spoiler:For all his talk about wanting to turn Omi to the Heylin side willingly, in the Season 2 finale he outright cheats by tricking Omi into using the Ying Yo-Yo to retrieve Master Fung from the Ying-Yang World (who is only there because Chase trapped him there), knowing that upon leaving he would be forcibly tuned evil.]]

* UniquenessRule: While in her ghost form, she's unable to use any Shen Gong Wu aside from the Reversing Mirror, as its natural properties mean that reacts to her oppositely to how other Shen Gong Wu act. The is especially convenient, as she needs to be the one to activate it in order for another person using the Serpent's Tail to restore her physical body.

* InvisibleParents: Jack's parents are never seen on screen but they are mentioned a couple of times in the show. They were mentioned to be rich and wealthy and apparently did not raise Jack as much as typical parents do. They often send his vast amounts of money to make up for their absences, which explains a lot on how Jack is able to afford a high tech house and create a lot of robot minions that are obviously expensive to make.

* ManiacMonkeys: His favourite Shen Gong Wu is the Monkey Staff, which gives him the appearance of a monkey and makes him act like one. He tends to be a bigger threat in this form than his regular one.

* BaldOfEvil: He has almost no hair on his head.
* BerserkButton: It really ticks him off when someone betrays him.

* MobileSuitHuman: His giant, spiky armor which he first appears in, but is afterward revealed to be a bean. It appears again a couple of times in season 3.

** ContraltoOfDanger: Has the deepest voice of all the women on the show to signify her BigBad nature.

* DitzyGenius: For all of his foolishness, Jack is undeniably a mechanical genius and can build everything from robots to mechas.

* BroughtDownToBadass: In later seasons Wuya may not be a PhysicalGoddess anymore, but she makes it up with superior martial arts skills, experience, and her own wits, allowing her to defeat the monks easily in spite of her weakened state.
