Spider-Man
Peter Parker, a photographer for a newspaper named The Bugle, is also the costumed hero Spider-Man. The source of his powers appears to be his black costume, which he can control with his mind. Other than being able to shapeshift into normal clothes, the costume also fires web-like projectiles from his wrists, which can be used either to swing from or to ensare his enemies. His superhuman strength and agility may also come from this suit.
He's kind of a smartass.
Spider-Man teams up with the Autobots to help rescue Sparkplug Witwicky from the Decepticons. Spider-Man notes that he has had many amazing and strange adventures in his long history as a superhero. Optimus Prime says that he is sure tales of his exploits would be interesting.
