Bruce Banner/The Hulk
Robert Bruce "Krenzler" Banner/The Hulk
Played By: Eric Bana
- "Even now I can feel it. Buried somewhere deep inside. Watching me, waiting. But you know what scares me the most? When I can't fight it anymore, when it takes over, when I totally lose control. I like it."
- Alliterative Name: Bruce Banner.
- Anti-Hero: Averted. His seemingly senseless rampages in the labs and military bases throughout the film are all attempts to destroy the gamma research before they fall into the wrong hands. He overpowers soldiers but never attempts to kill them.
- Driven to Suicide: By the end of the film, Bruce wished he would have been dead from his father.
- Like Father, Unlike Son: Bruce was completely terrified of his father since Bruce encountered David at his adulthood.
Elizabeth "Betty" Ross
Played By: Jennifer Connelly
Played By: Nick Nolte
- "We're gonna have to watch that temper of yours."
- Abusive Parent: David Banner killed his wife in front of his son before he planned to kill Bruce, resulting in him getting sent to jail.
- Adaptation Personality Change: David Banner started out as a hard-working, but loving father, so unlike in the comics. Though David does eventually become antagonistic, mostly for different reasons.
- Adaptational Villainy: While his Adaptation Personality Change already invoked this on him in the film, it's his Novelization counterpart who's really bad — lacking almost-all of Film!David's sympathetic qualities and being noticeably more selfish, Unfettered, and vindictive.
- Archnemesis Dad: To Bruce. After performing dangerous tests on himself, some of it was passed on genetically when Bruce was conceived. He attempted to murder Bruce but failed, striking down his wife in the process. Thirty years later, following his release from prison, he tracks down Bruce and attempts to rebuild their relationship while secretly plotting to drain Bruce's powers and alter-ego in order to rebuild his own decaying cellular structure and gain his revenge on the military. A very, very bad dude, though not without his sympathetic moments.
- Badass Normal: David Banner is just a threat to his son because of his high intelligence and how he believed in curing his son and himself.
- Beard of Evil: David Banner sports a big, scraggly beard in the present day after his years in prison.
- Big Bad: Of the film. He is responsible for destroying Bruce's life by experimenting on himself and his son out of an obsession with advancing humanity beyond its limits, creating the Hulk. He intends to drain Bruce's powers to regenerate himself and get his revenge on the military.
- Chewing the Scenery: Just before his transformation. Figurative and literal, as that page's image shows.
- Composite Character: Is based on Brian Banner (Bruce’s father from the comics), but later gains the powers of Absorbing Man, before transforming into a being of pure electricity similar to Zzzax.
- Create Your Own Villain: David experimented on his dogs with his sons DNA to be mutated.
- Despair Event Horizon: When he killed Edith and set off the Gamma explosion.
- Disappeared Dad: Bruce Banner did not see David again until his adulthood.
- Eldritch Abomination: After transformation.
- Elemental Powers: Everytime he touches rocks, water or electricity.
- Elemental Shapeshifter: His form after his mutation.
- Energy Absorption: His ability.
- Even Evil Has Loved Ones: David Banner is a monster, make no mistake about it - but he genuinely loved his wife and was devastated when he accidentally killed her.
- Evil Old Folks
- Fallen Hero: David wanted to make an army but was denied permission which led him descent into madness.
- Hoist by His Own Petard: David Banner gets exactly what he wanted so much, his son's dormant powers... too bad it's too much for him to handle and his body becomes so unstable that he gets blown up by the military.
- Hollywood Atheist: David believed religion "infected humanity's soul".
- Humans Are Bastards: David Banner's beliefs on humanity after his imprisonment.
- Professor Guinea Pig: David Banner experimented on himself after he was denied to create an army.
- Psycho Electro: His first form.
- Right-Hand Attack Dog: His subjects.
- Shadow Archetype: To his son, Bruce. Both are very brilliant researchers and have abilities based on different life forms.
- Tragic Villain: Even though David was devious, he had some regrets on his mistakes.
- Woobie, Destroyer of Worlds: David set off the Gamma explosion all because he wanted his work to get appreciated.

Major Glenn Talbot
Played By: Josh Lucas
- Adaptational Angst Upgrade: Talbot is more aggressive compared to his comic book appearances.
- Adaptational Wimp: Talbot is not the Colonel but rather the Major.
- Attack Backfire: His death. He fires a Grenade Launcher only for the round to ricochet off the Hulk and embed itself in the wall behind Talbot, who barely has time for an Oh, Crap! reaction before being blown up.
