Fighting Spirit

Fighting Spirit (気合, Kiai) is the fifty-fifth chapter of the OnePunch-Man manga series.

Part 1
Metal Bat is fighting Senior Centipede and Rafflesidon. Metal Bat and the two monsters seem to be fighting on equal ground until Rafflesidon begins releasing gases causing Metal Bat to enter a drunk-like state, unable to fully control his movements. Senior Centipede takes this opportunity to injure Metal Bat. However, Metal Bat is able to eventually escape the state by damaging his head, an action that surprises the two monsters. Senior Centipede decides to go for a finishing blow, but Metal Bat detaches Senior Centipede's arm. Metal Bat then proceeds to defeat the two monsters with a single strike each.
