Yu-Gi-Oh! GX has spawned some of the most Abridged Series out of all anime series, apart from Death Note. DarkSideIncorporated's original account was terminated by Nihon Ad Systems (and have now moved to "DarkSideCorporated"), and some of RaymsCreator's episodes have been blocked by 4Kids Entertainment.
Chew Toy: For constant emotional trauma, Syrus. For constant physical torment, Jaden (At least once an episode something or someone will cause him grievous bodily harm... and he's broken his coccyx more than once)
Cool and Unusual Punishment: During Wheeler the monkey's training to be a Duelist, every time it made a mistake, Miley Cyrus music gets blasted in his ears. Alexis wants in on this training.
Contractual Immortality: Unfortunately for Jaden, everyone is Genre Savvy enough to know he can't die. Hence nearly every single character has mortally wounded him at some point... including an off-screen dog who did something unspeakable to his legs and ate his liver.
Even Evil Has Standards: While more of a Jerkass than evil, even Jaden who constantly rags on Syrus and acts more like a dick to him than a friend admits that Zane was too much of a dick to Syrus when they were younger.
Heroic BSOD: Jaden was very much hoping Wheeler the monkey's deck would not be monkey-themed. Boy was he wrong. Also happens when Bastion disables Jaden's ability to Fusion Summon during the school Duel.
Jerkass Has a Point: Harrington, when Jaden says that having a deck of just what you love (Tennis in Harrington's case), is stupid. Harrington points out that he did the same thing with Super Heroes. Jaden then asks what the card he played does.
Vocal Dissonance: Also in general, this is apparent in the "In The Booth" videos. ShadyVox is the tall skinny guy while xTheDarkOne is the fat glasses guy. Guess who voices the high-pitched characters.note xTheDarkOne
Jaden: Oh, you watch me. I'll get this guy faster than the time I was invited to Crowler's birthday party and everyone got absolutely... ...made things worse and it was rumored that Chazz and Bastion had a gay relationship and no one believed it because... ...and Syrus was convinced that he was pregnant and then he made us go to the emergency room where—
Noodle Implements: After Yugi's deck is stolen, Jaden says they'd need an armadillo, a chess piece, and a car. The armadillo was later seen wandering the blue dorm, and Bastion believes they're not welcome there anymore.
Screw This, I'm Outta Here!: Jaden tries to surrender both his Winged Kuriboh card and quit the Academy because of how insane it all is, but by trying to quit he accidentally reforms the villain of the week and he gives up on trying to leave.
Jaden: I gotta comment. "First." Yes! I am awesome... I'm gonna ask him when the next one's going to be.
Episode 16's stinger has a subtle one in which the students complain about how lame Dmitri is for copying people and then claim next people are going to pretend to be Jaden and Syrus. Such people are sad bastards that only do it to get popular.
The Thing That Would Not Leave: Jaden sees Winged Kuriboh as this. He's tried selling it, he's tried trading it, he's tried sending it to Australia. It's like Droopy; it always comes back.
The Unintelligible: Chumley. He has been shown to speak perfect English on a few occasions.
Winged Kuriboh. Jaden can also understand him, though.
Vocal Evolution: Whilst ShadyVox and TheDarkOne have always been consistently good in the earlier episodes, the audio quality improved over the episodes. The higher quality professional setup probably helped too.
Bastion: There's a duel going on. On your left is Dimitri. Jaden:(looks right) Ooooh. Bastion: No, no, Jaden. Your other left. Jaden:(looks left) Ooooh. Bastion: And he's dueling Syrus. Jaden: I see. Bastion: ...He's on the right. Jaden:(looks right) Ooooh. Gotcha.
