–Mustafa fighting Shadow Dwellers
Mustafa the Dead One is a member of the Assassins Guild. He has the ability to form magical spheres from his flesh and throw them at his enemies.
Despite his immense size and strength, Mustafa holds Loki in high regards. It's possible that he knows what Loki truly is. It's unknown why Mustafa's face is deformed.
Mustafa is one of the last to report to Loki after the Assassin Cross summoned for his team. He uses his body to create spheres that he uses to break through one of Morocc castle's walls on Loki's orders in addition to attacking the Shadow Dwellers that assaulted them.
After their mission, Mustafa travels back to the Assassins' Guild with the others to find that their headquarters was no more. He stays behind with the others to help rebuild the guild while Loki hunts down the perpetrator.
