Maris Yamagata

Maris Yamagata is a recurring character in the Big Hero 6 franchise and Hiro Hamada's most prominent rival. She is the younger sister of gang leader Mr. Yama, who uses her skill with technology to aid in her brother's criminal escapades. She is voiced by Kiernan Shipka.

Appearance
Maris is a fourteen year old girl of mixed Japanese- Italian ancestry. She has fair skin, brown eyes, and her hair is dyed light brown and usually tied up in a high ponytail.

Maris' wardrobe is influenced by Japanese Oshare-kei fashion, and favours the colour pink.

Personality
As a foil to Hiro Hamada, Maris has many traits that compare and counter to him. Fully aware of the extent of her mental abilities, Maris is arrogant and relishes in any chance to show off how smart she is. She is even willing to brag to the rest of Mr. Yama's about how she is the real brains behind the operation. A talented con artist, Maris is able to switch between a coy and sweet personally to a brazen one at the drop of a hat. Life as a street kid has made Maris a strong believer in survival of the fittest, and she has little issue with lying and stealing. She does, however, draw the line at murder.

History
For unspecified reasons, Maris and her brother Claude became homeless when Maris was at least ten years old. The siblings got involved in picking pockets and rigging bets to survive. However, once discovering his sister's high intellect and expertise in inventing, Claude realized a new way to make money: bot fighting. Maris would design and build robots, and her brother would fight them in the ring.
