Melissa Shield (My Hero Academia)

Melissa is a kindhearted girl with a positive attitude and vast intelligence. Despite being Quirkless, Melissa works hard and desires to become a hero. She looks up to heroes like All Might, but admires her father the most. Melissa wants to help support heroes as her father does. She believes that by studying hard to create new inventions that she and her father can indirectly fight for peace.

Melissa is very outgoing and generous. She made quick friends with most of Class 1-A, especially Izuku Midoriya. U.A. students joined her for the I-Expo, where she showed them around its attractions and learned about Izuku's Quirk. Melissa generously gave Full Gauntlet to Izuku to help him reduce the strain on his body because the scars on his hand concerned her.

As a scientist, Melissa is naturally curious. She took Izuku out of his comfort zone when she got close to him to examine his hero costume. She is humble about all of her creations and wants them to go to good use. At the same time though, she expresses pride over her father, David, and surprised him by inviting All Might to the I-Island Expo. She was also clearly upset and devastated upon hearing that her father planned the villain attack in order to retrieve his Quirk Amplification Device, pointing out how Izuku and his friends were all harmed in trying to save everyone, although David genuinely believed that the villains he hired for the plan were fake.

Melissa embodies the will of a hero in the same way Izuku does. Despite being Quirkless, she remains calm and wants to help save people. During the villain attack on the expo, Melissa was a key player in releasing the island's citizens from Wolfram's grip. To save Izuku, Melissa even risked her life to tackle a dangerous villain.
