Mei is very talented with her love for inventing and building up new ideas of creating any type of Support Gear she could make. She often has a habit of calling her inventions by the word "babies". 

Despite her intelligence and gifts, Mei can often be obsessed with her inventing and sometimes goes too far, which often resulted in Power Loader scolding her for her recklessness. She can also be mischievous when it comes to testing her inventions on others, like putting white-metal armor on Izuku
