Masaya Aoyama

Mark (Masaya Aoyama in Japan) is one of the male heroes of Mew Mew Power who is Zoey Hanson's clasmate and love interest.

Mew Mew Power
Mark is Zoey's classmate. At the beginning of the series, he and Zoey go on a date to the red data animals exhibit where Zoey met the other Mews and became a Mew Mew herself. At first she thought Mark was oblivious to her feelings, but he later reveals that he shares her feelings and they begin dating.

Mark is the only person outside the Mew Project to know Mew Zoey's real identity, but initially pretends otherwise as he knows Zoey does not want him to know. He was supportive of it when she finally told him in episode 38, and said he would help her hide it.

Towards the end of the series, Mark reveals that as an orphan, he began acting like a "perfect child" to be adopted. In reality, however, he felt sick of humans and disgusted by how they treat the planet. He also reveals that Zoey is the sole exception, and it was only with her that he felt like a "real human being".

As the series progresses, it is revealed that Mark is the Blue Knight, but that Mark did not know that he was the Blue Knight, nor did the Blue Knight appear to have any knowledge that he was Mark. Once Mark becomes aware of his transformation, he realizes it was born of his desire to protect Zoey. Shortly after this revelation, Mark collapses and reawakens as Deep Blue, the leader of the aliens and the Mew Mew's final enemy.

Deep Blue claims that he created Mark in order to deceive the world until the time was right for his awakening. Mark sacrifices himself by releasing the final Blue Aqua inside his body in order to stop Deep Blue, and is revived when Zoey gives her life to save him. In turn, the Blue Aqua remaining his body then saves her.

At the end of the series, Mark decides to go to England to study the endangered species used for the Mew Project and the Mew Mews hold a mock wedding for Mark and Zoey before he leaves.

Tokyo Mew Mew a La Mode
In Tokyo Mew Mew à la Mode, Mark is the first to sense the new danger to the Mew Mews, and encourages Zoey to return to help her friends. Towards the end of a la Mode, he also returns to Tokyo.

Personality
Zoey describes Mark as "smart", "cute", "very athletic" and "popular at school". He is also depicted as being a polite and calm person, though he does have moments when he yells at others in anger and acts jealous and possessive regarding Zoey.

Relationships
Mark is an orphan, and his girlfriend is Zoey Hanson. Zoey's father, Mr. Hanson (Shintaro in Japan), dissaproved of Zoey and Mark's relationship, but Mrs. Hanson (Sakura in Japan), Zoey's mother, was supportive.
