Cow's Stomach

"Cow's Stomach" is a feared gang of robbers led by the A-Class bounty villain, Bull-Bull.

Members
Most of the members are unknown, but we do know some:

Appearance
Besides some exceptions, all members wear jackets with black and white cow prints on them, a hat with the same print and bull horns sticking out, and goggles. Some exceptions are Calf-Calf, who wears a hood over his head, Cow-Cow, who wears a face mask over his head, and an unknown member with a track suit who uses a bandanna to cover his face.

What Can't Be Bought
The gang robs a bank and gets away successfully with a child hostage after defeating Funeral Suspenders and D-Pad, but then their plans are ruined by Saitama, who defeats them all.
