Sid

From Devil May Cry Wiki

Sid is a weak demon who first appears in episode one, and has recurring appearances throughout the series. Initially seeming to be an insignificant danger and minor nuisance, Dante shows mercy towards Sid and restrains from killing him when given the opportunity. Unfortunately, Sid's ambitions prove to be far more dangerous than Dante possibly imagined. He later gains the power of Abigail, a powerful demon that once fought with the Devil King, but is defeated by Dante.
