Cassius Parker

Cassius is the major antagonist of Yin-Yang Yoh's Yu-Gi-Oh! ZEXAL continuity, more specifically, the Second Arc of the My Maiden's Series, My Maiden II. He is the son of, whose status in the My Maiden's Universe is clarified to be a Senator.

Appearance
Karaan is man in his late teens who has auburn hair slicked back, along with a pair of black square-framed glasses resting on his face. He is typically seen wearing a black suit in the real world, and dark red armor with a black suit that resembled spandex, along with a pair of dark silvery wings in the virtual world.

Personality
Like his father, he appears to be a caring and dedicated to philanthropy, but his true nature is similar to Senator Parker, but more twisted.

He is obsessive, somewhat vain, and above all, manipulative. He is usually seen giving a very carefree smile, where it is, for the most part, the opposite of fit to his words. With his facade of a smile, he has the ability to make the situation uncomfortable for the ones that he talks to, and ends up having it in his favor because of his contradictory expressions and threats.

Yu-Gi-Oh! ZEXAL
As the son of Senator Parker, he has just as many connections to the legal and criminal world as his father did, especially since Senator Parker had fallen into comatose from leaving his body. With heightened education and early graduation, Cassius takes over the role of being a substitute Senator for his father until he awakens from his coma.

One night, Vector, knowing about his connection to the body that Number 96: Dark Mist left behind, gives Barian's Force to him, with orders to find Yuma by using Kotori as a proxy. He stalks Kotori Mizuki, where he was then challenged to a duel, Yuma defending her. Yuma beats him, and in a rage, Cassius leaves, Vector disappointed and going back to the Barian World.

He then formulates a plan with Mia, who is possessed by Number 31, organizing a tournament within a Virtual World, claiming it to be an advancement in Solid Vision. He then has a comatose, brain-damaged Kotori under his watch, where he states that his medical facility is the only thing that can keep Kotori alive and the only ones with the technology to heal the damage done to her brain. This is later to be proven false. During the tournament, he is shown to have Kotori wired to a computer, while a live stream of the events in the world he created is running.

Yuma Tsukumo
Cassius hates Yuma Tsukumo with a burning passion, considering Yuma's close relationship with Kotori Mizuki, and the Mizuki family in general. He tries to beat Yuma in a duel in his first appearance, but was defeated by his. Afterwards, he formulates a plan with Mia, who is possessed by a Barian/Chaos Empowered Number 31: Heartbreaker. He is successful in separating Yuma and Kotori, showing his sadistic side to the former while Kotori is comatose.

Kotori Mizuki
Cassius has an unnatural obsession with Kotori Mizuki, stating his lust for her. Kotori naturally does not return his obsessive nature, is outright disgusted and tends to stay away from him, and his entire family. He still manages to separate her from Yuma, keeping her comatose state under her watch, admiring her, but knows he can't do anything about her while she is unconscious, due to the suspicions it would create in the hospital. However, he intends to marry Kotori, even if neither of them are at the legal age for marriage, but he still manages to create an event celebrating their engagement.

Deck
Cassius plays a Plant Lockdown Deck, which is based on the assumption of him controlling some Spell and Trap Cards. It really is unknown to what his deck truly is, due to the limited amount of cards that were shown.
