Bat guard

Bats were guards that Sly Cooper and the gang encountered in "Jailbreak" and "A Tangled Web" of Sly 2: Band of Thieves. They served as the Contessa's rooftop guards.

Description
They were gray bats with red eyes that wore a brown piece of shredded clothing. If they spotted intruders, they would call for backup by performing a bat scream, then charge at Sly with their pointy wings if they were successful. Sly could defeat them with three hits.

General Clawfoot, the head of security at Contessa's castle, is a modified version of a regular bat guard.

Trivia

 * Despite having wings, the bats show no ability of flight.
 * However this is in line with real vampire bats, which prefer to run instead of flying.
