In every Universe Peter Parker stands for heroism and responsibility, except for one. In my world the name Peter Parker puts fear in the hearts of everyone who hears it. Heroism and Responsibility, I destroyed every fool who held such ideals. Until this shard come to my world, I thought I was the only Peter Parker. But now, with the power of the complete Siege Perilous, I will be.
~ Wolf Spider

Wolf Spider (real name: Peter Parker) is the main antagonist of the "Return to the Spider-Verse" episodes of Ultimate Spider-Man.


Not much is known about Wolf Spider's past, although, it can be assumed that, just like the original Peter Parker, he was bitten by a radioactive spider, but decided to use his new powers to become a supervillain. He found out about the Siege Perilous when a shard fell into his world and sought to use it to conquer the other spider-verses. He used the shard to travel to the Vampire Universe and create a fake alliance with the Lizard King. He battled Blood Spider, Spider-Man, and Kid Arachnid in the sewers and stole the shard of the Siege Perilous. In the end, he revealed himself to the duo and his plan. Wolf Spider tried to steal the two shards from them, but failed and uses the shard that he has to go to the next dimension.

Wolf Spider later appeared in Kid Arachnid's universe at a police department where he and Spider-Man found the next shard. Before he fought Spiderman and Kid Arachnid, he revealed that he had Kid Arachnid's mother as his captive and used her to gain an advantage over the two Spidermen. Luckily, Gwen Stacy, Kid Arachnid's substitute during his absence, showed up and helped them fight Wolf Spider. During the battle, Wolf Spider removed his cloak, revealing four bio organic spider arms on his back, which he used to fight them. As Kid Arachnid assaulted him, the shard he had showed him turned out to be the final piece that Wolf Spider used to guide him. This final piece joined together to recreate the Siege Perilous. As Kid Arachnid rejoiced with his mother, Wolf Spider broke into his house. He took the Siege Perilous from Spider-Man and removed his mask, revealing his identity to them. He then left with a trail of destruction for the heroes to follow him. Gwen Stacy, Miles Morales, and Peter Parker found him at a underwater cave, where they saw him draining energy from all the other Spider-Men, thus making him grow stronger. Gwen and Kid Arachnid took Wolf Spider head on, but ended up having their powers drained from them too. As he confronted Spider-Man, Spider-Man asked him if he drained the powers of all the Spider-Men. Wolf Spider replied by saying, "ever last one." This made Spider-Man decide to let his powers be drained from him. Unfortunately, the powers were too much for Wolf Spider to handle, which caused him to shatter into a million pieces.


Wolf Spider doesn't really care about anyone but himself. He doesn't even care about his dimensional counterparts. He is only obsessed with getting more power and ruling worlds. It is revealed that he pretends to join other villains who have shards of the Siege Perilous, only to help him further his goals.


Wolf Spider was first seen wearing a dark hooded cloak over his body and a goggled mask over his face that was hiding his true identity. As he revealed himself to Spider-Man, he wore dark blue jumpsuit and had four robotic spider arms on his back, sharing similarities to Iron Spider. He looks similar to Peter Parker, except he has darker hair, paler skin and red eyes.
