Bruno Costa is a villain in the Marvel and an enemy towards The Punisher.
Bruno Costa was one of the Mobsters that was responsible for the murder of Frank Castle’s entire family and in effect created the Punisher. Sometime after Frank Castle became the Punisher, he managed to find, capture, and execute Bruno. After Bruno's death, he wound up in Hell. While he was in Hell, Bruno ended up in the service of the demon called Oliver.
After Bruno was killed and sent to Hell, he is now able to use any of Hells weapons. He can produce virtually anything from thin air such as axes and swords that contain magical properties.
