bat devil (chainsaw man)

The Bat Devil is a devil who embodies the fear of bats. He is the primary antagonist of the titular Bat Devil arc and a minor antagonist in the War Devil arc.

At some point the Bat Devil became the boyfriend of the Leech Devil.

The Bat Devil was nearly killed by a human but managed to escape after losing his arm. Later he encountered Power on top of a farmhouse in the countryside, taking her pet cat Meowy prisoner to make Power cooperate with him. He demanded that she bring him a human so that he could drink their blood in order to regrow his severed arm.
