Tim. He — as Yoshi — has been attacked by steam in Luigi's Engine Room, chased by a giant boulder in DK'S Jungle Adventure, bitten by a Pirahna Plant in Peach's Birthday Cake, and eaten by a giant fish on Yoshi's Tropical Island.
In New Super Mario Bros. Wii, Josh Jepson gets his turn at this; while NCS tends to die as often as him, he at least gathers more lives, meaning Josh usually has the least lives and the most deaths.
Mario Party 3 hates Jon. He just can't catch a break, and the game seems to take every chance it can to give him the worst of all possible outcomes.
Chromatic Arrangement: Both in terms of characters in New Super Mario Bros. and of names in Brawl, Chugga is Red (the fearless leader), Jon is Blue (he tends to be more proficient and knowledgeable of the games than the other two), and Tim is Green (the most laid-back and gentle of the three). Josh even fulfills the Yellow fourth member part of the trope.
Mario Party's Pot o' Skills has another fantastic one after Jon beats everyone in Tug of War.
Genre Savvy: The Guys are well aware of their fanbase's...peculiarities...and in particular when Jon and Chugga argue, they often exploit it by challenging the fans to make embarrassing fanart or fanfiction of the other.
And the fact that TV Tropes has labeled NCS as The Medic and Josh as The Chick. It's pretty much confirmed by now that they've been reading this page.
Only Known by Their Nickname: Averted in the case of NCS, whom the two others address by his real name, Tim, quite often. Played straight with Chuggaaconroy, even though his real name, Emile, is widely known. And subverted by ProtonJon, whose nickname contains his real name. (No, it isn't Proton.)
Emile: His first name is Proton, his last name is Jon. Plot twist!
Ironically, NCS does usually call him "Proton" rather than "Jon".
Finally averted with Chugga in New Super Mario Bros. Wii in World 6.
Red Oni, Blue Oni, Purple Oni: Chugga and Tim could be seen as this trope, while Jon rapidly switches between red and blue at times. The other two are always red and blue, though.
Tempting Fate: All of them have done this - sometimes accidentally, sometimes on purpose to the other Guys. Jon in particular seems to have mastered weaponizing it against Emile, but Emile has done this to Jon on occasion as well.
True Companions: They're willing to travel across the continent just to hang out, and they always have each others' backs, even if they do ham up the Vitriolic Best Buds thing.
Verbal Tic: Chugga has a habit of suddenly saying "Luigi!" whenever NCS does something of note in the New Super Mario Bros. Wii videos. Josh also did this a couple of times.
In Kirby's Return to Dream Land Chugga does the same thing, but with Dedede rather than Luigi.
NCS tends to fill any dead air with tics like "Holy crap", "Oh my God" and "This is crazy", while Josh does the same with "Oh my goodness".
One of the main three Runaway Guys, Chugga is usually the best or at least better players of whatever game the group is playing. He also tries to annoy ProtonJon as much as possible and allow for situations where the viewers can laugh at the group's collective suffering. In the Mario Parties, he played Donkey Kong. In Super Smash Bros, he played Ness. In Mario Kart 64, he played Wario. In New Super Mario Bros Wii and New Super Mario Bros U, he played Mario. In Kirby's Return to Dreamland, he played Kirby. In Fortune Street, he played Bowser Jr. (except for the Slimenia board, where he played Donkey Kong). In the Tournament Arc of Super Smash Bros. Brawl, he played Lucas. In Mario Power Tennis, he played Bowser Jr.Wins: Mario Party (5 out of 8 boards and the Minigame Stadium), Super Smash Bros. Brawl SSE (tied with Jon for overall winner), Super Smash Bros Brawl Free-for-all (won both matches), Mario Party 2 (2 out of 6 boards), Mario Power Tennis tournament (won with Bowser Jr), Wii Party (Board Game Island), Fortune Street (won Mario Stadium board), Burnout Revenge (had the high score), Mario Party 3 (2 out of 6 Battle Royale boards; 2 out of 6 Duel boards)
A Day In The Lime Light: Not Chugga himself, but the fact that he plays as Donkey Kong in the Mario Party games contrasts with his individual channel where he's never played a Donkey Kong game or even a game that has Donkey Kong as a playable character.
His hinted-at offscreen moments of...something note For example, he apparently tried to kiss everyone one night make Jon question this more. Strangely, he never shows any signs of this in his own LPs, so he could just be deliberately acting weird to make these videos funnier.
This habit of his leads to some very strange trains of thought on his part, like concluding that making pizza by going to the bathroom is an awesome power and that the final boss of Kirby's Return to Dream Land is the king of Hawaii.
Better than a Bare Bulb: If there is any form of coincidence, irony, or status quo change in either the game or with the three of them, Chugga will point it out sooner or later.
Born Lucky: As per his normal LPs, Chugga has huge strokes of luck in Mario Party, including winning the majority of the boards, having his stars switched with the leader at the last second thanks to Chance Time, and running into multiple Star Spaces in one turn.Subverted concerning the dice rolls that determine turn order, as he keeps getting to move last.
Also, in the sequel, getting a last second hidden star on the final turn in Pirate Land, ultimately leading to his victory.
Jon points this out in Horror Land of Mario Party 2 and refers to it as Chugga's "stupid luck".
Chugga himself lampshades this in Fortune Street by yelling "SUPER LUCK ACTIVATE!" when gaining a free teleport to the bank. inverted due to him being consistently dead last for the entire game.
This is actually kind of funny when you consider how Chugga's solo videos normallygo.
Call Back: Chugga has referenced the Runaway Guys videos in his then-current solo LPs — Pikmin 2 and Luigi's Mansion. He specifically references "Don't Eat The Mushroom" whenever a poison mushroom shows up in the mansion.
Whenever a minigame is won, he will often say, "[Winner] takes it!"
Character Development: He starts out in Mario Party rather normal, only having occasional Large Ham or Cloud Cuckoo Lander moments, with pretty much the only real humour from him coming from his rivalry with Jon. By New Super Mario Bros. Wii, however, he's become much more entertaining.
Character Exaggeration / Flanderisation: After the incident in the first LP about him never having seen an Indiana Jones or Back to the Future film, Jon now reacts with exaggerated shock every time Chugga mentions he's seen any film.
Similarly, in Mario Party 2, Jon likes to exaggerate Chugga's love of the Wario "DOH, I MISSED" catchphrase (together with Chugga's encyclopaedic knowledge of games) by claiming Chugga has an annotated list of every single situation in the game where the catchphrase appears.
Jon: Have we come to the realization that Emile just lives in his own world when it comes to commentary?
Crazy-Prepared: He states himself as such here because he practices for his LPs months in advance while talking to someone else. This is so he can adjust to the multiple factors that come with other people being around while focusing on playing the game. He also keeps everything super organized according to Jon and Tim and is usually the person with the most knowledge of their current project.
This is most noticeable in New Super Mario Bros. Wii, where Chugga plays pretty well despite stating elsewhere that he isn't good at 2D Mario games. In a later LP he mentions that he's incapable of beating New Super Mario Bros. Wii when playing alone, which you wouldn't expect from his performance in the LP.
Crouching Moron, Hidden Badass: Not stupid, per se, but tends to not play too well in Subspace Emissary. However, when they reach normal matches rather than platforming, he proves to be quite competent.
He shows this even more in the bonus battle and tournament, doing amazingly well in both. He wins both of their matches in the bonus battle, and reaches fourth place in the tournament. And he likely could have gotten even higher, if he hadn't lost his first match due to a rolling crate spawning and ramming him offscreen.
Curbstomp Battle: He's on the delivering side in Mario Power Tennis, constantly. He was one of the only ones to practice, though.
Determinator: According to Jon's Formspring, Chugga really wanted to be Player 1 in Kirby's Return to Dream Land since the three of them hadn't changed player numbers since the beginning, despite not being terribly good at the game. So he allegedly powered his way through the game in order to prove to Jon that he was capable of being Player 1. And he was, once the project began.
Griefer: Usually the one that screws the other guys out of victories.
The Hero: The unofficial leader, due to his gaming skill. Furthered by him always being Player 1, except in Subspace Emissary, where the guys took turns as Player 1, Player 2, and not playing.
Hidden Depths: In episode 3 of Kirby's Return to Dream Land, it's mentioned that he can beatbox.
Hoist by His Own Petard: Lost his tournament match against SuperJeenius, thanks in part to accidentally losing a life at low damage.
Later, he loses to Diabetus when he forces the match into Sudden Death. Though to be fair, if he didn't do that, he would've lost anyway, since Diabetus was about to kill him.
Hypocritical Humor: Tortures Jon with the "Move faster Pokey" line for fun, but reacts in pure agony whenever Jon mentions Steve.
Iconic Outfit: His polo shirts, which Jon tries to exaggerate into a Cargo Ship. Even the game Wii Party joins in by randomly assigning a striped colour scheme to Chugga's Mii in one minigame that makes it look like he's wearing a polo shirt.
Troll: It's difficult not to imagine Chugga making a trollface when he makes an Incredibly Lame Pun or screws Jon over. His teachers always said (and he agrees) that he does not work well with others, which explains why he acts differently than in his solo videos.
Unfit for Greatness: As far as the Kirby's Return to Dream Land LP goes. He fancies himself the leader at all times, but he doesn't know Kirby nearly as well as other games or as much as Jon knows Kirby. Still wants to be the leader. See Determinator above.
Viewers Are Geniuses: Given his tastes are lean towards the obscure, and his tendency to gush over things he likes, expect a lot of references that may not seem familiar at all.
"Well Done, Son" Guy: He seems to want to impress ProtonJon (his inspiration to be an LPer) in the Super Smash Bros. Brawl playthrough.
Young And In Charge: He is the youngest of the three core members, and he is also the one in charge of maintaining the YouTube channel, editing the footage, and uploading the videos.
One of the three main Runaway Guys, Jon is also a great player, but is usually messed up by the game or Chugga. Tends to act like he's Surrounded by Idiots. In Mario Party 1, Mario Kart 64, Mario Party 2, and Super Smash Bros. 64, he played Mario. In New Super Mario Bros. Wii and New Super Mario Bros. U, he played Blue Toad. In Kirby's Return to Dream Land, he primarily played as Meta Knight (switching to Waddle Dee and Kirby in situational cases). In Fortune Street and Mario Party 3, he played Waluigi. In Super Smash Bros. Brawl, he played Ike. In Mario Power Tennis, he played Luigi.Wins: Mario Party (2 out of 8 boards, won the most games on Minigame Island), New Super Mario Bros. Wii (overall winner), Super Smash Bros 64 (won both the round-robin and free-for-all), Mario Kart 64 (won the Balloon Battle), Super Smash Bros Brawl SSE (tied with Chuggaaconroy for overall winner), Super Smash Bros Brawl Tournament (won with Ike), Mario Party 2 (won 4 out of 6 boards), Kirby's Return to Dreamland (overall winner), LittleBigPlanet (overall winner), Wii Party (won Globe Trot, Spin Off and Bingo), New Super Mario Bros. 2 (collected the most coins), Fortune Street (won The Observatory and Slimenia boards), New Super Mario Bros. U (overall winner), Castle Crashers (overall winner), Mario Party 3 (1 out of 6 Battle Royale boards; 3 out of 6 Duel boards, overall Duel winner).
During Mario Party, he says "PENTAGON PUNCH!" a few times, referring to Mario's rather pentagon-shaped glove.
During New Super Mario Bros. Wii, his main catchphrase was "Bye guys!" when he ran further from the rest of the pack.
He says "Thanks, X!" after someone references X person or media, and sometimes says "...Really?" when Chugga makes a reference or joke he considers to be a bit of a stretch.
"Only you." whenever Emile does or says something weird.
Tended to use "Happy Birthday!" to Chugga whenever screwing him out of a collectable in the Kirby's Return to Dream Land run. Well, during the period immediately surrounding Chugga's real life birthday.
For the Evulz: After getting over Chugga nearly giving him a black eye in New Super Mario Bros. Wii, he's still determined to make Chugga use a continue. When asked why, he simply says "Because I can!"
Handicapped Badass: During the Smash Bros. filler video, he beat Chugga and Tim, while using a controller he wasn't used to.
During the Tournament, it was revealed that he didn't get a lot of sleep and was tired beforehand. And he won anyway.
Hipster: Repeatedly calls himself as such. Especially in LittleBigPlanet, where he enjoys sticking hipster glasses on everything.
Hypercompetent Sidekick: During Kirby's Return to Dream Land. He has to point things out to Chugga, who insists on still leading the team.
Chugga: We're the horrible ones, you're the sort of normal one.
Purple Oni: The calm and collected one during Mario Party (most of the time). Switched to red from blue when New Super Mario Bros. Wii started up. Ironic, considering he plays Blue Toad. Yes, Jon not only shares this trope with another Runaway Guy, but has actually been on both ends of the trope's spectrum.
Ron the Death Eater: In-universe during Kirby, he's hit hard with this by Chugga, who thinks that everything Jon does or says is taking a shot at him. Even lampshaded in Episode 12.
In Mario Party, he does this to the game itself, as seen in Catch Phrase above.
In Subspace Emissary, he repeatedly yells "TIM!" due to Tim's frequent screw-ups.
In Fortune Street's The Observatory, he ecstatically yells his own (character's) name when Tim lands on his shop and has to pay him 841 G, complete with the trademark Mexican-ish accent: "WALUIGIIIIIII!"
Took a Level in Jerkass: Goes from somewhat annoyed with Chugga in Mario Party to outright trying to kill him (and occasionally Josh) in New Super Mario Bros. Wii. Even more after Chugga accidentally gives him a black eye.
He goes back to "normal" in Subspace Emissary, though he still tries to annoy Chugga whenever possible.
Troll: In episode 14 of Mario Bros., he actually starts being more annoying again because he hasn't "been trolling enough" apparently.
He Tries very hard in the last videos to get Chugga killed enough times to have to use a continue. He even asked Josh and Tim to help. (It failed.)
He had the most teammate kills, and was Chugga's leading cause of death.
In the finale of New Super Mario Bros U, he kills everyone else at the same time during the first part of the Bowser fight. The cutscene prevented everyone from bubbling after he pushed the switch to collapse the floor.
Another of the main three players, NintendoCapriSun (also just "NCS" or "Tim") is the quietest and nicest of the three. This usually means Chugga and Jon will beat him, though he's not by any means bad at games. In the Mario Parties, Mario Kart 64 and Fortune Street, he played Yoshi. In New Super Mario Bros Wii and New Super Mario Bros U, he played Luigi. In Kirby's Return to Dream Land, he played King Dedede. In Super Smash Bros, he initially played Yoshi in his match against Chugga, then switched to Fox for the remainder of the video. In the Tournament Arc of Super Smash Bros Brawl, he played Diddy Kong. In Mario Power Tennis, he played Yoshi.Wins: Mario Party (1 out of 8 boards), Mario Kart 64 (Rainbow Road), Fortune Street (Yoshi's Island), Wii Party (Swap Meet), Mario Party 3 (3 out of 6 Battle Royale boards, overall Battle Royale winner; 1 out of 6 Duel boards)
Attention Deficit... Ooh, Shiny!: It's been theorized by the other Guys that the reason he keeps dying in the games is because he's not paying much attention as he plays.
This was definitely present in the final stages of Subspace Emissary, where Tim died or caused the others to die constantly. Reached its logical conclusion in this superb Non Sequitur right at the end.
Beware the Nice Ones: Despite being likely the nicest of the trio, he has his moments of awesome. He also shows this in real life, such as when he got tired of a troll starting an argument in the comments of an episode of Little Big Planet and stepped in to shut them up.
Blue Oni: Even calmer and more careful than Jon was in Mario Party. Plus, it sticks during the transition to New Super Mario Bros. Wii.
Catch Phrase: Aside from the ones from his regular playthroughs, he has taken to usually using a simple "Dahh!" when he screws up, rather than yelling, cussing, or narrating what just happened like Chugga and Jon.
Whenever a beach level appears, he often makes the same "Son of a beach!" pun.
If he makes a reference that someone else points out, he has a tendency to say "I'm afraid so."
He often responds to Chugga's puns with a distinctive "Augh!"
Cloud Cuckoo Lander: Somewhat. He tends to talk to himself in the background, usually while others are talking over him, so viewers will often only catch snippets of what he's saying and wonder what the hell's running through his mind. This can often lead to an Orphaned Punchline.
Crazy-Prepared: Usually averted, a lot of his problems stem from lack of experience with the games the Guys are playing. New Super Mario Bros U is an exception though—he has played it enough to have practically memorised it (as Jon points out) and it shows.
After faring poorly on the first two Mario Party games thanks to lack of experience, he practiced Mario Party 3 for a year before the LP (according to Chugga). The result? He won the LP.
Dark Horse Victory: Teased for Yoshi's Tropical Island, but Jon won instead. Tim did, however, win earlier at Wario's Battle Canyon.
Gasshole: NCS belches several times in just about every video.
Lampshaded once when they pointed out that someone other than him belched.
On Yoshi's Tropical Island, once the rest of the group got a whiff of something, he admits he'd passed gas three times by that point.
Hidden Depths: He shows that he is very skilled at button mashing in Mario Party 2. He even avoids being caught by Chugga in Crane Game, when Chugga had 40 seconds to go.
Mad Libs Catch Phrase: Eventually, he keeps making his 'in the bathroom' joke, but replacing the last word with anything relevant.
He also does this with his "A bee?!" catchphrase, switching it out with anything relevant that rhymes, such as "A key?!"
Magikarp Power: After struggling through much of the New Super Mario Bros. Wii run, he ends up practically carrying the team come the final stage.
As the guys make more projects, his overall skill seems to be slowly improving. He was rather clumsy and incompetent during Mario Party 1, less so in New Super Mario Bros. Wii, was able to hold his own in Mario Party 2, had the fewest deaths for a decent chunk of Kirby's Return to Dream Land, ended Little Big Planet with the second-fewest deaths... time will tell if he will be able to challenge Jon as The Ace.
The Medic: During New Super Mario Bros. Wii, he usually pops the other players' bubbles.
Nice Guy: Tim is very gentle compared to the others, only stealing from the CPU during Mario Party. He also never dicks over anyone else during NSMB Wii, either by intentionally using them as springboards or grabbing them and throwing them down pits.
This also adds a bit of Fridge Brilliance as to his low score on Mario party; nice guys finish last.
He's begun abiding by this a bit less in later playthroughs; while he doesn't act like a total jerk and avoids screwing with the others when they need to use teamwork, he has stopped going easy.
Only Sane Man: Almost the entire time in New Super Mario Bros. Wii. Also during other games, though to a somewhat lesser extent.
Out-of-Character Moment: Any time NCS sends his voice skyrocketing for one reason or another (to the extent he outdid even Chugga) usually ends up catching everyone involved off guard.
Phrase Catcher / Say My Name: Chugga has a tendency to shout "(Go) Tim!" (or "Luigi!" in the New Super Mario Bros Wii LP) whenever NCS does something noteworthy, either good or bad.
He seems to be getting this in New Super Mario Bros. Wii. So far, he's died on the first Goomba, lost more lives than anyone else, and was the first player to have to use a continue. This can mostly be attributed to his nice guy nature in refusing to use everyone else as springboards, and falling to his death (except once). And as Josh Jepson pointed out in a comment, he actually feels he's doing worse than Tim because Tim never usesthe bubble mechanic. On the bright side, he's collected a good majority of the Star Coins so far, but the LP is too early on to say for sure if this will be a constant.
He does seem to be doing better than Josh now, but he's still miles behind Chugga and Jon in the long run.
This was lampshaded in a Facebook post:
[Chuggaaconroy]: Tim can do 3-heart runs of Zelda, beat Contra on Hard with no continues, and even beat Super Ghouls & Ghosts, yet despite all this, he does not understand the concept of pressing A to not die.
Chugga finally came out and just asked him about it, and Tim responded that it's the control sticks in general that mess him up so bad. The evidence matches up, as all the games he's pulled off incredibly well were before the advent of analogue sticks. Also, the fact that there are more players on the screen was mentioned.
He's doing better now in Mario Party 2, but unfortunately the Random Number God is still causing his overall performance to suffer.
Mario Party 3 became his turning point, where he won three out of the six main boards.
Pungeon Master: Not to the same extent as Chugga, but he does make quite a few puns. And they're generally given a warmer reception.
The Quiet One: A common complaint in the earlier Mario Party videos is that the normally very talkative NCS was being far too quiet; all three contributors promised that he would come out of his shell in later videos. And so he did, but he's still definitely the quietest of the three.
He does do a lot of talking, though, but mainly to himself in the background.
Inverted twice in the filler videos. In the Super Smash Bros.. round-robin tournament, his "Let's get ready to RUMBLLLLLLLLE!" was so loud and long that it left Jon and Chugga dumbfounded, then when he won in the lost recording of Mario Kart 64, his Big "YES!" reached Chugga levels of loud.
Jon also mentions in his interview with LPCatchPhrases that NCS is a generally quiet and shy person, so part of it is probably him warming up to his new team members.
Role Association: NCS is much more consistently associated than the other two with playing as a single character (Yoshi) across many different games the Guys play.
Smug Snake: Not normally, but his loss in Fortune Street, Delfino Plaza was in part due to him being arrogant while bidding on one of Chuggaa's shops, causing him to spend too much and blow his lead.
While still the only one to never win a match, he did KO Jon once or twice during the Smash Bros. filler video, and then won Rainbow Road during the Mario Kart video.
He's also gotten loads better as of Mario Party 2. However, due to Jon and Chugga also being a bit better and luck usually not going in his favour, this tends to not show as well as it should.
The Mini-Game coaster showed that he got exceptional in playing the mini-games, particularly Hot Rope Jump. The challenge is that you have to jump fifty times and he did it on his first try!
And in Fortune Street, he was consistently staying in first place with a huge lead, and then, he won even when Jon seriously threatened his victory. Emile did cheer Tim on and strategically put what little money he had into Tim's stocks at the end, but it was mainly Tim's own win over the usual ace of the team.
He plays very well in New Super Mario Bros U. As of episode 14, he has the second least deaths and is actively gunning for the star coin lead.
By Mario Party 3, he won Deep Bloober Sea due to a Hidden Block and good use of his items. He then won Spiny Desert, and as if that weren't enough, he THEN won Woody Woods by a mere 21 coins! That makes him the victor of more boards than the previous 2 Mario Parties COMBINED.
The special guest Runaway Guy during the New Super Mario Bros. Wii and New Super Mario Bros. U LPs, where he played Yellow Toad. He also played as Link in Super Smash Bros. Brawl tournament, Koopa Troopa in Mario Power Tennis, Luigi in Super Smash Bros. 64, and Donkey Kong in Fortune Street.
People making fun of his name by connecting him to George Jetson.
He dislikes lava.
He also quickly grows tired of people replying to his Catch Phrase "I'm JoshJepson, but you knew that already" with "You're Josh Jepson?" and "Oh my god you guys, Josh Jepson's here!", as Chugga learns. Several times.
During Mario Wii, he is always trying to get 1-Ups, but can never get enough thanks to bad luck, dying too much, and Jon hogging them.
In the Smash Bros. Brawl Invitational Tournament, he is the first of the guys to lose a match and be sent to the "losers" side of the bracket (shortly followed by Tim). Then, later in his match against Chugga, he almost never landed a single hit on him, with the Shy Guy racers doing most of the damage for Josh.
Then we have the 64 Tournament where he loses to Tucans, who has never played before, with Luigi.
He also blows a 2-0 lead against Super Jeenius and gets eliminated completely.
After starting fairly well in New Super Mario Bros U, 9 episodes in, he has almost as many deaths as everybody else put together.* 33 for Josh, 36 for everyone else combined.
Role Association: Bizarre meta example in Kirby's Return to Dream Land, when the other Guys associate Josh with Waddle Dee (any Waddle Dee) purely based on the fact that he would hypothetically be playing as Bandanna Waddle Dee if he was present.
The Guys' first official female guest, and second guest in a main project overall (LittleBigPlanet). She also played as Ganondorf in Super Smash Bros. Brawl, Peach in Mario Power Tennis, Jigglypuff in Super Smash Bros. 64, Daisy in Fortune Street, and Koopa in Mario Kart: Double Dash (on Team PressBallsToContinue with Dodger).
Noob: The Observatory playthrough is her first time ever playing Fortune Street, and Jon acts as Mr. Exposition to explain it to her. (They note that this is actually a good thing, since in the previous playthrough, the Guys launched straight into the game without much explanation of the rules, and many fans unfamiliar with the game got confused by its mechanics).
In the Brawl tournament, she loses two battles in a row, both of which are curb-stomps, and to Lucas, a character she apparently hates.
And again in the Smash 64 tournament, where she uses Jigglypuff and gets absolutely destroyed in her first match, then loses to Donnabellez in the loser's bracket after stalling for a good few minutes (although they were both apparently a tad drunk at the time).
Became the Guys' third main guest when he joined their LP of Castle Crashers. He also played as Zelda/Sheik in Super Smash Bros. Brawl, Mario in Super Smash Bros. 64, and Stella in two Fortune Street boards.
Foreshadowing / Lying Creator: The Guys mentioned at one point that they'd meet up with him, and later it was confirmed he would not be their guest player. And here he is now. Not lying per se, but it was tricky.
Hero Killer: Defeats Chuggaaconroy for good in sudden death, even after Chugga was buying himself time to kill him there first, and previously Diabetus had knocked Tim out of the Tournament. He's responsible for two out of three Runaway Guys losing the tournament.
The Quiet One: Not as much as ALoyalGamer, but more than other guest fighters, he likes to be quiet and focus on playing. He eventually makes some jokes and puns starting with his second match. In the MKDD tournament, he is by far the quietest person in his race as Slowbeef spends most of their turn yelling.
Running Gag: Mentioning that he's sleepy and that he's playing while asleep.
Vitriolic Best Buds: With Donnabellez during their match. Jon is shocked by how they treat each other. Anybody who's seen Super Mario Galaxy Versus is not.
Mal (played Pikachu in SSB, Toadette/Paratroopa in MKDD, on Team Stephenplays with Stephen)
Stephen Plays (played Ness in SSB, Baby Luigi in MKDD, on Team Stephenplays with Mal)
He Also Did: Stephen and Mal also made the new (2013) Runaway Guys logo.
Took a Level in Badass: He loses the first round of Smash 64. After that, he keeps on winning and manages to make it to the finals of the loser bracket before being beaten by Pcull. Keep in mind that Jon considers Pcull a Worthy Opponent so that really says how impressive Stephen did.
Unfit for Greatness: In Double Dash he never lets Mal drive. The reason for this becomes clear in a later video series he does with her where they play versus matches of different Mario Kart games - Stephen thought he was better than Mal at Double Dash. As that video series shows, he waswrong.
The Ace: He went undefeated during all the tournament, he was the responsible of knocking out two of the three main Guys, and additionally, he won the Smash 64 Tournament. A first in TRG, where someone else other than the main Guys ended victorious in a tournament.
Hero Killer: Defeats Chuggaa, then Jon in both the Winners Bracket finals and in the Finals rematch.
Honor Before Reason: During his match with Jon, he manages to get the Hammer which would have given him a clear advantage, but intentionally waits until the powerup times out so he can fight Jon fair and square. He wins anyway.
Troll: Part of his commentary style. In particular, when it's pointed out that a certain randomly chosen stage keeps showing up in fights with Pcull (one where he keeps using the mechanics of the stage and Ness' abilities to help him win) he claims that he's hacked the game to make it happen.
