The Hulk has been teleported to a galaxy far, far way. He was dumped into the Star Wars Universe conveniently close to the Death Star, occupied by Darth Vader, and 50 members of the Emperor's Royal Guard, and 500 Storm Troopers (everyone else is on vacation). The Hulk crashes into the Death Star, which, thanks to safety precautions, seals automatically. The entire DS staff is alerted, including Vader. They all make their way to the invader, encountering him on various floors of the Death Star
47th floor: Hulk vs 25 Storm Troopers. All are carrying pistol-sized blasters
33rd floor: Hulk vs 100 Storm Troopers. 75 are carrying pistol-sized blasters, the other 25 wielding large, mounted blasters
12th floor: Boba Fett, passing by coincidentally as the shenanigans ensue, investigates. He follows the commotion down to the 12th floor, running into a squadron of Storm Troopers and members of the Emperor's Royal Guard about to face off with a raging, green monster. He decides to join the fight
Hulk vs Boba Fett and 150 Storm Troopers. The Sith opponents in this fight have been relayed information from previous fights and thus have knowledge on their opponent. Boba Fett is at full capacity, equipped with his flame thrower, concussion grenade launcher, whip, and wrist laser. His jetpack is able to reach the 150ft ceiling of he 12th floor. There are 5 Emperors Royal Guards, and they are equipped with their usual force pikes. The Storm Troopers are all equipped with heavy machinery.
66th floor: Darth Vader finally finds the Hulk. Darth Vader and 10 members of the Emperor's Royal Guard engage.
Hulk vs Darth Vader and 10 members of the Emperor's Royal Guard
50th floor: The Hulk vs Fully rejuvenated Darth Vader and Boba Fett
50th floor, round two: The Hulk vs Emperor Palpatine and Fully rejuvenated Darth Vader. Darth Vader relays information to the Emperor before the fight begins.
Does The Hulk have what it takes to clear it?
(I apologize for not knowing the actual interior of the Death Star)
EDIT: Gave a little bit of prep.
