The creator of the versus series, and usually the editor. He tends to be very sexual and inappropriate with his commentary to a hilarious degree, particularly by how casually he makes jokes of the sort. So far, he appeared in all of the Versus LPs.
Played a bit more straight later on, when he dies literally right before getting the Shine Sprite in a level he had been having lots of trouble with. He ends up breaking down crying for a little bit.
Even Evil Has Standards: Despite trying to win and usually trying to screw with the other person so he can gain an edge, he'll still sometimes help them out if help is needed, or extend a video's length so they can finish up.
He also starts posting Content Warnings during Galaxy Versus after seeing how much swearing and such was present in Sunshine Versus.
Totally Radical: Uses this way of speaking sometimes, particularly his constant usage of the word "totally" (occasionally shortened to "totes").
Troll: During Sunshine, he flips Josh's screen upside-down in editing for a few minutes. Then in part 5 of Galaxy, not only does he get away with losing fewer star bits from a Bit Blowout, he previously had Donna do a double Bit Blowout.
Later in episode 24(?) he reveals that he once won a prize for being best Christian Boy Scout in the state of Missouri.
Tyler: ...WHAT WENT WRONG?!
Yank the Dog's Chain: When it seemed like he was going to win 64 versus, along with winning his first versus ever, he died near the end of the final red coin mission. Josh caught up, and won the versus because of that.
The first person Tyler raced against, and his usual opponent. First appeared in Sunshine Versus and Luigi's Mansion Versus, latter of which he hosted and edited. His commentary is a bit like Tyler's, likely due to being around him, but not nearly as bad and he is usually the more down-to-earth of the two.
Aw Look They Really Are Friends: Mentions how much fun he had doing Sunshine Versus with Tyler at the end of the project, despite the constant bickering, yelling, and fighting the two did throughout the whole thing.
Sir Swearsalot: Less than Tyler, but still enough to qualify for this trope.
Sore Loser: He's friendly and agreeable most of the time, but when he's noticeably falling behind, his temper and vocabulary reflect it. Tyler lampshades this during the Spirit Temple episodes of Ocarina of Time Versus.
The third person Tyler raced against, appearing in Sonic Adventure 2 Versus. She's about as vulgar as Tyler. Her team is the 'Lucah Troopas.' At the time of writing, she has yet to have a proper appearance on the Versus channel.
The Determinator: Even when she got a game over in Eternal Engine, and Final Rush, she still tried to beat Tyler in those levels even though she knew she would have to start all over. Doesn't stop Tyler from winning in those two levels though.
Heroic Self-Deprecation: Whenever Eggman appears on-screen, she'll make a comment about how alike they are in terms of appearance.
Bad Liar: When he tries to convince Josh that he was still doing Barrel Cannon Canyon and was messing up in it when he already finished the level.
Curb-Stomp Battle: The first episode of Donkey Kong Country MOOSE, where he beat Josh in every level in that episode. The only reason that the MOOSE wasn't over in the first episode was due to Josh and Stephen adding a rule that the loser of a level only gets a letter if they lose a level they don't choose so that Donkey Kong Country MOOSE wouldn't be too short.
The second episode of MOOSE was this as well, with Stephen winning without getting a single letter.
