Rumored Monster Arc

He says that he will go take a look for himself and see the truth behind the rumored ghost town with his own two eyes.

Garou Introduction Arc
Blue Fire, Magic Trick Man, and Heavy Tank Loincloth are assigned to keep the criminals gathered by Sitch in check. During the meeting, Speed-o'-Sound Sonic steals a pamphlet and reveals the reason behind the meeting. He declines to help the association. Blue Fire is angered by this and confronts Sitch.

During the meeting Garou begins his rampage and easily defeats Magic Trick Man and Heavy Tank Loincloth. Blue Fire intervenes and attempts to cremate Garou, but Garou dodges, and the flame hits the criminals behind him. Garou rips Blue Fire's forearm off and knocks him out.

Supreme Hero Arc
After Sweet Mask reveals his true form, Blue Fire arrives at the scene to help fight Pesky Clown. He observes the destruction caused by the fight and reasons that the monster is very powerful.
