Squadron
Scaledon had been captured for study and exploitation by Metal Knight then handed to former coordinator of the Z-City Hero Asociation Branch, Guiches, who intended to sell its scales to a collector of monsters. However, the creatures new feeding habits while in its sheltered environment caused it to mutate into a more vicious form, breaking free from containment and eventually escaping into the forest which divides Cities Z and Y.

When it is made apparent that a shift in environment and diet caused an alarming growth spurt, information of which is withheld, a group of B ranked heroes; pertaining of which is Caped Baldy, are sent out to dispatch it without harming the creature. When the hero group, minus Saitama, catches up to the beast he is already caught within numerous snares set up by one of their number Trap Tengu, all obstructions of which prove ineffective as the monster easily rips through them all. It dispatches all the heroes who confront it head on and eventually devours them one by one.

Saitama eventually catches up to it just after it finishes the last hero of the team, as the former demands the monster to spit them back out as he wants to quit the team in front of their faces given that they belittled him and left him behind while out on the hunt. Scaledon instead opts to eat him whole, reuniting Saitama with the rest of the unconscious crew. Seeing as taking it in alive was no longer feasible the hero quickly blew a hole out of its back, freeing both himself and whatever else Scaledon had consumed along the way, killing it instantly.
