Cow's Stomach

Cow's Stomach is a notorious band of thieves under the command of Bull-Bull, a villain who carries an A-Class bounty. The gang's identity is built around a bovine theme that runs through their whole look.

Most members dress in jackets patterned with black-and-white cow markings, matching hats fitted with jutting bull horns, and goggles. A few break the mold, including Calf-Calf in a hood, Cow-Cow behind a face mask, and an unnamed member who wears a track suit and hides his face with a bandanna.

The gang's function is straightforward robbery, and their signature caper unfolds in an extra story. While Saitama was inside the ABS Bank to make a withdrawal, Cow's Stomach stormed in, seized a boy as a hostage, and ran into the C-Class heroes Funeral Suspenders and D-Pad. The pair took out several members before Bull-Bull overpowered them, and the crew fled by car toward the mountains to dump the hostage and vanish with their loot.

Their escape collapsed when Saitama caught hold of the vehicle and hauled it to a vending machine in a park. The stunned robbers piled out to fight him and were flattened just as quickly.

Most of the gang remains unnamed, but a handful are known. Bull-Bull leads the crew, Cow-Cow serves as the driver, and Calf-Calf acts as Bull-Bull's right-hand man, with additional unidentified members rounding out their ranks.
