Bloodscream was once a 16th century sailor, whom a necromancer turned into a pseudo-vampire a condition that could only be cured by drinking an immortals blood.
During the 20th century, he serves as a soldier in Nazi Germany from 1935 to 1945. He sees action during World War II and first encountered the man then known only as Logan, who would later become Wolverine, during the Battle of Normandy ( June 6 - August 25, 1944), when Wolverine is a corporal of the Canadian Forces. The two engage in a brief battle with Bloodscream being stabbed and left for dead.
He runs into Wolverine decades later in Madripoor and notices that Wolverine hasn't aged since his encounter with him decades earlier. This leaves Bloodscream to believe that Wolverine's blood will work in the formula to transform him back into a human. He properly introduces himself to Wolverine while working in Madripoor as a criminal enforcer with his partner, Roughouse. During this time, he often comes into conflict with Wolverine, who was at the time in his alter-ego as "Patch", though he's never able to defeat him. He nearly kills one of Wolverine's close friends, Archie Corrigan, managing to scar his chest with a handprint before being interrupted.
After he parts company with Roughouse, Bloodscream enters a partnership with Cylla Markham of the Reavers, who at that point is tracking Wolverine for reasons of her own. He joins her in tracking Wolverine all throughout the high Canadian wilderness and they finally locate him, though both he and Cylla are near death from hunger and fatigue. Knowing he has no chance against Wolverine unless he's at his peak, Bloodscream turns on Cylla and drains her of blood. Bloodscream then confronts Wolverine, who is armed with the honor sword of Clan Yashida. The sword is a katana forged by demon blacksmiths from a fallen meteorite. As the sword wasn't forged by mortal man, Bloodscream is vulnerable to it and is struck down by Wolverine, who again leaves him for dead.
However, Bloodscream later reappears, apparently having turned over a new leaf; he works with Albert and Elsie-Dee for a while. This reform was short-lived, though, and Bloodscream reverts to villainy and begins working as a mercenary again with Roughouse. He encounters Wolverine a few more times and has recently been involved in a confrontation with Iron Man in which he was beaten.
Bloodsport was created by Chris Claremont and John Buscema in 1989 and first appeared in Wolverine # 4.
Bloodscream is not a true vampire hence his powers differ greatly from other vampires. Bloodscream is able to walk in daylight without fear of disintegrating nor is he susceptible to crosses, wood, garlic or silver unlike other vampires. Bloodscream possesses superhuman strength, speed, reflexes and a regenerative healing factor similar to Wolverine's.
Bloodscream is capable of morphing into a bigger more grotesque feral like creature with elongated claws and razor fangs, usually he takes this form when extremely aggravated or in a blood lust.
Bloodscream is capable of animating his victims and turning them into undead zombies that are under his control.
Bloodscream is capable of controlling humans by simply limiting the amount of blood he takes keeping his victim alive but unable to resist his commands. He normally does this by marking his victim by placing his hand on them and drawing small amount of blood in the shape of his hand.
Bloodscream is capable of running down and chasing vehicles at phenomenal speeds in the superhuman range. Bloodscream has chased down Wolverine on foot for weeks while Logan was on his Motorcycle eventually catching up to him at a rest stop.
Bloodscream possesses superhuman stamina he has been able to maintain his running speed for days and weeks only occasionally stopping to feed.
Bloodscream possesses a healing factor similar to the level of Wolverine's what makes it even more disturbing is that he maintains full autonomy even if decapitated able to reattach his own head. his regeneration further increases with the amount of blood he feeds on. Another noticeable difference is that he cannot die by conventional means or if it is even possible since his existence is tied to the necromancer curse, he can only die and suffer fatal wounds that negate or slow down his healing factor by items not made by "Mortal Hands" and even then it is only temporary.
