Acts of Vengeance: Cosmic Spider-Man punches The Hulk into orbit.
Amazing Spider-Man and Captain Universe’s Uni-Power
Captain Universe is endowed with the Uni-Power, a sentient energy field that seeks out people in great peril and bonds with them. In another sense, it is every person–it is the potential for heroism that lives in each of us.
When the Uni-Power chooses a partner, it endows that person (or, rarely, persons) with the powers, memories, and costume of Captain Universe. The partner can use the powers of Captain Universe until the peril is surmounted. However, if the partner tries to use those powers for personal gain or for evil, the Uni-Power immediately deserts them.
When a lab accident granted Spider-Man the Uni-Power, his costume was cosmically changed into the Captain Universe outfit by the Uni-Power. This form gave him incredibly enhanced senses, strength, speed, flight, a new costume and limited telekinesis.
