!!John Bender
->'''Played by:''' Judd Nelson
* AbusiveParents: His father is a physically abusive alcoholic, who also beats his wife.
* AntiHero: Type IV or V.
* 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. I dare you.
* BookDumb: For someone who's made out to have plenty of school trouble, Bender is scarily articulate and intelligent.
%%* CoolLoser
* DeadpanSnarker
* [[FourTemperamentEnsemble Five Temperament Ensemble]]: Sanguine
* 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.
%%* IneffectualLoner
* {{Jerkass}}
** JerkWithAHeartOfGold: His sympathetic qualities are buried so deeply under so much antisocial behavior and cynicism that it comes off as a HiddenHeartOfGold at times.
* HeroicComedicSociopath: Straddles the line between this and a SociopathicHero.
* LastNameBasis: Note how the other kids refer to him simply as "Bender".
* MilesGloriosus: He puts out an image of toughness but Andy is able to take him down with ease. Even when Bender pulls a knife and casually talks about killing Andy, he's slowly backing away from the fight.
* MouthyKid: When Vernon attempts to find a solution to keep the door open. Bender's comments are both hilarious and true.
* 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. He was the first to tell that Claire is a virgin before Allison made her admit it and was the first to notice that Andrew didn't like his parents before Andrew tearfully admitted it in the end.

* {{Adorkable}}

-->'''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?
-->'''Vernon:''' Hey, Carl. You think I give one rat's ass what these kids think of me?
