Baseball Hero: Slugger is a Pro Hero. He is a tall, skinny man with orange hair. He is among the heroes who are trying to stop the Sludge Villain who is controlling Katsuki Bakugo; but Slugger cannot do anything since the villain is too fluid. None of the heroes who are present can attack the villain, so Slugger clenches his fist in anger. As Slugger and the others wait for a hero who is able to defeat the villain, Izuku Midoriya tries to help Katsuki. Slugger and the other heroes try to stop him but Izuku ignores them. All of the heroes then try to help him, but before they can do anything, All Might manages to defeat the Sludge Villain with a Detroit Smash. Slugger and the other heroes then clean the area.
