Chuck

A mysterious green creature resembling a small dog, kept at the church. It possesses unusual features, such as zippers on both its head and rear, and has the peculiar ability to eat anything and then regurgitate it. Its cry is "Chuck!" and, together with thunder, it receives hints from the heavens and expels them from its mouth.

Chuck’s regenerative abilities are supernatural; even when it is frequently kicked, beaten, or reduced to a mere lump of flesh, it revives instantly. Because of this, it is often referred to as one of the three sandbags. Sometimes, it collapses instantly at the start of a battle.

Chuck is usually seen acting together with Garterbelt and Stocking Anarchy, and it’s sometimes seen driving a see-through vehicle. Chuck has a long-standing rivalry with Fastener, having fought many battles in the past. If the zipper on its head is opened, Chuck temporarily loses consciousness, allowing a man residing inside its brain to step outside.

When Chuck gets serious, the zipper on its rear is released, causing its insides to turn inside out and triggering its full-charge form. In this state, its colors change and it transforms into a giant four-legged beast with a pair of horns, making it an enigmatic existence.
