Medica is a quite and reserved person, when talking to the Player. She rarely shows any form of emotion and is the most serious character out of everyone else featured in the game, with the exception of Boomstar, as he is a robot. When at her job, she becomes extremely serious, as her job itself is a very serious matter.
Medica is a super batter, using a giant syringe with pink fluid as her bat. Like all other batters, she possesses unique skills that enhance her as a player.
