Direct text from Devil May cry wiki:
One of the gatekeepers of Temen-ni-gru, half-blinded and sealed away for 2000 years by Sparda, Beowulf is a winged beast who anxiously awaits his chance at revenge. He possesses overwhelming strength and a variety of light attacks.[5]
When Dante enters Beowulf's chamber, he senses that Dante has "Sparda's blood", and attacks. Dante blinds Beowulf, and when Beowulf tries to chase down Sparda's scent he instead finds Vergil, assuming him to still be Dante. However, Vergil immediately kills Beowulf and he falls apart, realizing his mistake. Vergil then takes Beowulf's soul as a Devil Arm. Dante later obtains it after Arkham activates the Temen-ni-gru and Vergil falls into an abyss.
