The Spirit Spider Suit appears as a clothless white body with a spider symbol on the chest and a skull and blue flames for a head.
It comes with the Spirit Fire suit power. When activated, this ability sets Spider-Man's skull ablaze as well as his attacks, letting him spread the fires of hell to enemies that will take damage and be stunned by the blue flames.
The suit is based upon the Spider-Man outfit from Incredible Hulks Annual #1, where it is donned by Ghost Spider, a Peter Parker from Earth-11638. In this reality, Peter is killed and later resurrected with the help of Dr. Banner, becoming the Ghost Spider.
