“A Hulk by Any Other Name…”
Writers: Gerry Conway & David Michelinie
Artist: Alex Saviuk
Spider-Man takes the doohickey that zapped him back to New York and puts it in a storage locker. Betty and Jameson are furious for him leaving Betty like he did. He leaves the office, not feeling so well, and turns into Hulk on the roof. He calms back down and makes his way to the scientists lab and figures out what the device does. He retrieves it from some punks who stole it from his locker and zaps himself to suck the Hulk energy back out. He becomes normal again.
