History Characters / TeenageMutantNinjaTurtles2003

* ContrastingSequelAntagonist: In Season 4, after taking the role of The Shredder, she's much more active in hunting down and murdering the Turtles, to the point that she destroys their lair and most of their vehicles in the process, rather than being as passive as Ch'Rell.

* HeterosexualLifePartners: With [[UsagiYojimbo Miyamoto Usagi]].

* EliteMook: IThey serve as the absolute best fighters of the Foot, second only to Shredder himself.

* ArchEnemy: He's the one that has most actively attempted to murder the Turtles, being part of the reason they came into existence to begin with.

* PartyScattering: He and Drako as Ultimate Drako are the ones responsible for sending Donatello to the infamous "[[Recap/TeenageMutantNinjaTurtles2003S3E21SameAsItNeverWas Same As It Never Was]]" universe with the Shredder ruling all, while Leo winds with with Usagi Yojimbo.

* DealWithTheDevil: In exchange for sparing the Tengu's life, Saki merge with with him and gain unspeakable power.

* FreudianExcuse: In the 1800s, Bishop was a soldier in the Civil War who was abducted by aliens, being experimented on and genetically altered, turning him into the xenophobic WellIntentionedExtremist he is in modern times who's willing to cross any moral boundary in order to keep Earth safe from alien incursions. Given his past, it's quite understandable why he became the man he is today, though in no way does this justify all the lives he's ruined and the people he's hurt.

* PetTheDog: Downplayed. While he can throw it away at a moments notice, he seems to have ''some'' level of affection toward his higher level lieutenants; he personally raised Karai, trained Hun, rarely ever significantly punishing them, and they're also the only ones he listens to. He also respected the power of the Foot Mystics, which they reciprocated to some extent, even when they thought he was an "abomination".

* PetTheDog: Bizarrely enough, he ''respected'' the power of the Foot Mystics, enough for them to reciprocate somewhat.

* ContrastingSequelAntagonist: He's much less subtle and more active in his pursuits to kill his opposition, and doesn't have a goal involving getting back to his home planet or getting revenge; he just wants to TakeOverTheWorld.

* PlotHole: Due to the reveal that the Shredder in this series is an Utrom, why he has distinctly ''humanoid'' clones is never adequately explained.

* {{Expy}}: He shows more than a few similarities to [[TeenageMutantNinjaTurtles1987 Lord Dregg]].
