* AttentionWhore: Will seemingly do anything to attract your attention.
* AxCrazy: This generally implies in him, particularly in the "I want to be an Airborne Ranger" scene.
* BerserkButton: Call him a liar. We dare you.
* BookDumb: For someone who's made out to have plenty of school trouble, Bender is scarily articulate and intelligent.
* ByronicHero
* CoolLoser: Bender is an outcast in the school, but looks like a cool guy to hang out with when he isn't being psycho.
* DeadpanSnarker: Often makes snide remarks towards Vernon.
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Sanguine
* FreudianExcuse: His violent behavior [[AbusiveParents comes from his dad]], as deep down, he's unhappy about life in general.
* HeroicSacrifice: Bender draws the attention of Vernon after the Club runs into a dead-end during their hallway jaunt, allowing the other four to get back to the library undetected.

* LastNameBasis: Note how the other kids refer to him simply as "Bender".

* SarcasticClapping: "That was great, Claire. My image of you is totally blown."
* SmarterThanYouLook / JerkAssHasAPoint: While he isn't book smart, he is able to cleverly deduce things about the others.

* CloudCuckooLander: Exhibits a lot of spastic behavior, as one may think she's mentally ill.

* LonersAreFreaks: She's often ignored by everyone, including her own parents causing her to do bizarre things.

-->'''Carl:''' Aw, bullshit, man. Come on, Vern, the kids haven't changed; ''you'' have. You took a teaching position because you thought it'd be fun, right? Thought you'd have summer vacations off. And then you found out it was actually work, and that really bummed you out.
-->'''Vernon:''' These kids turned on me. They think I'm a big fucking joke.
-->'''Carl:''' C'mon…listen, Vern, if you were sixteen, what would you think of you, huh?
