The brain. Most people don't appreciate brains, they don't understand how beautifully complex they are. However, Y/n L/n did, and she wished she didn't. Synopsis: Y/n L/n was a happy, healthy little girl who lived a happy, healthy life. She had a loving mother and a caring sister. Sure, her father was a little mean, and sometimes she had to ignore the screams echoing down the hall, but that was all normal. She lived a normal, happy life. When she was 5 years old, her quirk manifested, and when it did . . . it would wreak havoc on her normal, happy life. Quirk: Brain Invasion Y/n L/n can 'invade' any brains in her general vicinity. She can run 'mental interference' so other mental quirks usually don't work on her. She can mess with hormones, recognize and alter brain signals, and she can shut down the parts of the brain. Most importantly, she can shut down the brain entirely.
