Life as zombie
Nothing is known about Bub before he became a Zombie, but as the movie focuses on him, there's more to him. Bub was first seen in Dr. Mathew "Frankenstein" Logan's Lab. When Dr. Sarah Bowman was sent to inform the former of Captain Henry Rhode's meeting, Bub sneaks up on her only to be restrained by a chain leash attached to the wall. He watches curiously when Logan discusses with Sarah what drives the dead to keep moving and his intent to domesticate them as a temporary means to halt their hunger for flesh. He is later seen when Sarah and Dr. Ted Fisher are invited by Logan, to observe his progress. It is there he reveals he named Bub after his father, a rich surgeon. He let Bub "live" because after many failures, Bub was a success so far. At Sarah and Ted's observance, Logan shows Bub a few toys to help him learn. A toothbrush and a shaving razor, which he used before and a book (Salem's Lot by Stephen King), which was part of a new addition to the experiment. While Bub plays with the razor and tooth brush he throws them away after a while. When he starts reading the book, Logan congradulates him enthusiastically. Ted argues how pointless it is, due to him witnessing the dead do similar things such as trying to drive a car. However Sarah argues, that it's more on the fact that he didn't attack or try to eat Logan during the demonsration. Rhodes and his Private, Walter Steel; interuppts their conversation at first acting hostile towards Bub, but Logan insists that Bub is docile. He invites them all in the room and hands Bub the phone in an attempt to get him to speak. Steel think's its ridicuous and Rhode's just examines the clipboard. When Bub speaks saying "Hello Aunt Alicia." Rhodes drops the clip board in shock, gaining Bub's attention. Bub, apparently recognizing Rhodes as a soldier, offers a salute to Rhodes, causing Steel to laugh. This prompts Logan to believe that Bub was in the military in life. Logan asks Rhodes to return the Salute, which he refuses, seeming to anger Bub. As part of a demonstration, Logan asks Sarah to empty her pistol and hand it to Logan. As a show of respect, Logan then salutes Bub before placing the pistol on the table. Bub looks at the pistol and cocks it, aiming at Rhodes, prompting Rhodes to pull his own loaded gun on him. Bub tries to fire his gun, only to hear the pistol click, reacting in fear that the gun is empty. He puts the gun back down, but Rhodes refuses to lower his own, intending to kill Bub. Logan stands between them, protecting Bub.
Bub is later seen with Logan playing with a set of headphones he has on his head. When Logan tries to adjust the headphones for him, Bub instinctively grabs his arm before letting him go, showing his trust in Logan. Logan adjusts his headphones, while teaching him how to play the tape recorder. The music being played was "Ode To Joy." By Beethoven. Music Bub seemed to enjoy. When Logan shut it off, Bub was at first saddened, but per Logan's teachings, learned how to play the tape himself so he can listen to it whenever he wanted. After Logan makes his note, he turns off the recorder to tell him, that it's time for his reward. Unbeknownst to both of them, this particular demonstration is observed by Sarah and William "Bill" McDermott. Who came to the lab to get morphine for the bit Private Miguel Salazar. They discover much to their horror, that Bub's reward for being docile is being fed human flesh as postive reinforcement. Matters get worse when Rhodes walks in an discovers the travesty. They discover the source of the flesh is the remains of soldiers that have been killed, prompting Rhodes to shoot Logan killing him. Bub is later seen locked up with another Ghoul and he figures out how to get the chain off his leash, freeing him. While that is going on Migeul in a frenzy has lead a horde of the dead into the facility prompting everyone to scatter. When Bub goes to show what he learned, he discovers Logan's corpse in the freezer. When he realizes Logan is dead, he becomes greiving and enraged. He discovers Sarah and Ted's discarded guns and picks one up. When Steel tries to flee for his life, he runs into Bub. Bub who recognizes Steel tries to shoot him. He misses and Steel flees into one of the rooms, trying to get the drop on Bub. Before he can, the horde surrounds him and he shoots himself before they could devour him. When Rhodes heads for the Armory to get an M16, Bub ambushes him. He tries to load his gun in a panick, only to drop his clip when Bub shoots at him. Rhodes attempts to flee, but gets shot in the left shoulder crippling him. When Rhodes tries to furhter flee, Bub shoots him in the leg, prompting him to crawl his way to the nearest exit. When Rhodes manages to get to his feet and at an unlocked door, he is greeted by more of the dead. He tries to turn back only for Bub to shoot him in the stomach. The horde devours Rhodes before Bub mockingly salutes him. Bub leaves, never to be seen again.
