Spiderman (Ultimate Spider-man)

"He's a cross-species... and yet, he still has the appearance of a Human.... Interesting..."

    --OSCORP Scientist Matt Jacobson

Spiderman (Peter Parker) is the main protagonist of the Ultimate Spider-man series. He found out that Dell Adams was the new Venom, and decided to try to come up with some way to turn Dell back to normal.

Dell Adams Incident arc
Peter Parker had just left school, when he ran into Venom. Venom was injuring officers and knocking over cars, so Peter ran into an alley, and Spiderman ran out. He tried to convince Venom to stop hurting people, and he mistook Venom for Eddie. Spiderman was surprised when he found out the Symbiote found a new host, but that didn't stop him from attacking Venom. They fought for a few minutes, but when Venom injured Spiderman, he had no choice but to retreat. Peter took of the suit, and went to the Hospital. He went to the emergency-room due to infected flesh wounds, and he was later put into a regular room. Peter wondered why the symbiote would choose a new host... He left the Hospital after a few days, and went to OSCORP to talk to Matt Jacobson.

When he arrived at OSCORP, Peter got to talk to Matt Jacobson; who also knew the Venom Symbiote found a new host. Although, Matt needed a sample of the Venom symbiote in order to confirm that it had a new host, so Peter put the suit back on, and went out to go find Venom.
