- Anti-Hero: and a Byronic one - type IV or V, as usual with these.

- Big Damn Heroes: Does this in "Night of the Evading Dead" in Season 4.
- He pulls one off again in the Season 6 finale "The Reunion" when he runs over Trent with a Scorpion just in the nick of time... without even knowing he did so until after performing the task.

- Catch Phrase: plenty.
- Character Development: A little. Since the start of the series, he's started to care more about Arbiter, even admitting that he is sort of his friend. It is even hinted that he cares about Claire a little in "Remission", and in "Severance", after fragging Kylie, he looks back at the corpse of her avatar before going after Arbiter, which implies that he's feeling a little bit of regret.
- Cluster F-Bomb: used to be much more frequent.
- Completely Missing the Point of Arbiter's speeches.
- Crouching Moron, Hidden Badass: RARELY, Chief is capable of pulling random CMOAs with no warning.

- Kick the Dog: Occasionally has moments like this, such as his attempted murder of Greg.
- The Lancer: Plays this role to Arbiter in more recent seasons.
- Leet Lingo/Rouge Angles of Satin: All the time.
- Pet the Dog: For all his horrible acts (and his entire attitude in general), he can show signs of genuine kindness, with the most outstanding moment being in "The Reunion", where he reassures the Arbiter that he will not die alone, and that the Master Chief, despite all of his comments towards the Arbiter, does appreciate his companionship.
- Saying Sound Effects Out Loud/Unsound Effect:

- Weapon of Choice: An assault rifle and the Spartan laser, though recently he has traded in the laser for a rocket launcher.

- Your Mom: a frequent target of his jokes.
- Anti-Hero: he combines aspects of types I, II and III.
- Author Avatar: As acknowledged by Jon in an interview.
- Author Filibuster: Delivers many that speak of Jon's opinions on the gaming world and specific games. While he makes good points, the fact that the plot will oftentimes slam to a halt for the Arbiter to deliver a filibuster in his Microsoft Mike voice can be grating to some viewers.
- Big Damn Heroes: He pulls one off at the end of the episode "Hard End" in Season 6.
- Catch Phrase: "Sigh". Though it does not catch that very frequently.
- Deadpan Snarker
- Don't Explain the Joke: "I see what you did there. Instead of addressing my points, you took everything that I said and turned it into a sexual joke, implying that I suck on men's penises. Fantastic.".

- Fair Cop Now that he is a TOSER

- Jerk with a Heart of Gold: in varying proportions as time passes. Demonstrated in "Recon" (S1E2) and "Evil" (S3E12).
- Knight in Sour Armor
- Let's Get Dangerous: Arby goes up against Chief and his crew with a pistol and Sprint to prove a point. Guess who wins.
- Also, when in casual situations online, he tends to wear Minor armor, in other more serious situations he switches to Spec Ops.
- Only Sane Man: not until recently - there was Todd, Cortana and quite a few relatively sensible players on Xbox Live. Now it seems that most of the other gamers are portrayed with more or less the same level of intelligence as Chief.

- Pre-Mortem One-Liner: He's used two so far. One for Adam, and another for Silent Strike.

- Just Friends: Doesn't return Arbiter's feelings. They still have a healthy relationship though.
- Killed Off for Real: Is fragged in S6 E9 by Adam

Also at the beginning of the season he is calm and only swears during a Precision F-Strike, but as time goes by and Arby and Chief interfere more and more and things start to stop going his way, he descends into several Cluster F-Bomb.

- It seemed more like he was just asking Kylie if people with that mindset got to her, he doesn't exactly have a politically correct mindset, especially as the episode Cradle to Grave reveals that his gamer tag is "back2thekitchen88"
- Screw This, I'm Outta Here: In "Femme Fatale", Duncan decides that he has had enough of what Chaos Theosis is doing and that it isn't right. Shortly after, Kylie assassinates him.

- The Sociopath
- Villainous Breakdown: In episode 10, Cradle to Grave.
- This deserves a bit of expansion: Adam is cornered by Arby and Chief in a private server, he tells one of his "friends" to take them out. This "friend" who had been threatened with a permeant ban by Adam that very episode refuses to, saying that he's had enough of Adam. At that moment, Adam's mother walks in with a police officer, saying that Adam is going to a correctional facility. He breaks down, desperately pleading with his Mother not to send him away. He begs Arbiter, Chief and his "friend" to vouch for him, upon which his friend remarks, "Lock his ass up and swallow the key". As Adam is dragged away, he begins swearing furiously, as the Arbiter coldly shoots him in game...Ah, Karma.
Adam: "YOU'LL FUCKING PAY FOR THIS ONE DAY MOM YOU HEAR ME?! I HOPE YOU DIE IN A FIRE YOU FUCKING CUNT! I HOPE YOU FUCKING DIE!
- Your Mom: He uses this a lot. Not as much as Chief though.
