Mei is a reasonably short girl with quite a mature build. She has salmon pink hair, which is generally shoulder-length, although it does vary, which is styled into thick dreadlocks and sideswept to her right. Her eyes are wide and sloped upwards with some notably long upper eyelashes, their irises yellow with a cross in the centre, making them look somewhat like scope lenses.
In her first appearance, she wears the regular U.A. gym uniform (a dark blue tracksuit decorated with the letters “U” and “A”), but she also adds some of her own gadgets onto it, including red and gold steampunk goggles, a utility belt to hold the various tools she carries around, oversized speed-assisting boots, and what could possibly be a jet pack strung over her shoulders.
She’s later seen wearing a plain black tank top with workshop coveralls tied casually around her waist, with the same goggles on her head.
Mei is a smart, off-setting, and assertive girl, often making those around her uncomfortable. She loves creating gadgets, which she refers to as her "super cute babies". Mei has a habit of "going straight to the point" and is very shameless and opportunistic when it comes to advertising her inventions. While talking to people, she has a habit of getting awkwardly close to them, which usually causes them to back away from her but she still moves up to them. She is also manipulative, as she tricked Tenya Iida into using her support equipment to promote her inventions.
Mei shows no fear when it comes to failing, seeing it as an opportunity to learn and do better next time, which is why she does not mind when her inventions fail. Mei can be seen as self-centered due to putting her love of inventions and gadgets above others, but this selfishness is not a negative as it is out of motivation to improve herself. She does seem to be a little bit absent-minded as she is easily distracted and can sometimes be completely unaware of her surroundings, as shown by her inability to sense one of her inventions catch on fire as she was speaking with Izuku Midoriya. Furthermore, she seems inept at reading body language and social cues, apparently being oblivious to Izuku's discomfort with her proximity to him on several occasions.
Overall Abilities: Outside of her intellect, Mei mostly acts as a support rather than facing battles directly. However, she proves to be a capable combatant as seen in her match against Iida, where it lasted for ten minutes with Iida unable to do anything to her despite his speed advantage and only winning when she forfeited.
Expert Inventor: Mei is very smart and innovative, creating many different pieces of equipment on her own that can help her in many situations. She relies mostly on her inventions to traverse obstacles and tasks. Power Loader acknowledges Mei's talent in the field of inventing, calling her one of a kind.
Skilled Manipulator: Mei is good at manipulating people, shown when she tricked Tenya into modeling her inventions during the Sports Festival final round Tournament. However, Tenya was already very gullible anyway.
Business Savvy: Mei has a good mind for business. She took full advantage of the Sports Festival, as the stands were full of scouts from major Hero Support Equipment Companies. She teamed up with Izuku during the Cavalry Battle, knowing that people would pay attention to him, since he finished first in the previous competition. She also spent the entirety of her match against Tenya (a full 10 minutes) demonstrating and explaining her inventions to the crowd.
