The villainous team of the Galar region. Designed after soccer fanatics in behaviour and Punks in appearance, they are a toxic group of people who look up to Marnie, an upcoming challenger wishing to become the Champion of Galar. Though their admiration for her is pure, they make sure to use any means necessary to stop anyone else trying to become the Champion so that she succeeds.
- Abhorrent Admirer: Downplayed: Marnie doesn't seem to hate them, but their efforts to "help" her are usually pretty disruptive, annoying her and forcing her to tell them to stop. Considering that they're the Gym Trainers for her older brother's Gym and are essentially supporters from her hometown, it would be rather awkward and difficult to get them to stop otherwise.
- Affably Evil: Despite the fact that they're the villainous team of the Galar Region, they seem very friendly when they're not causing trouble. Their only goal is to make sure that their idol Marnie becomes Champion and even try to give support to other Gym Challengers at times. This is because they're actually not an evil team; they're the Gym Trainers for the Dark-type Gym disguised as one to distract other Gym Challengers and increase the chances of Marnie becoming Champion.
- Anti-Villain: Possibly the biggest example for a villainous team in the franchise. All the trouble they cause is nothing but loud disruptions, blockades, and challenging people, all at the wrong times. This is because they're actually not villainous; they're the Gym Trainers for the Spikemuth Dark-type Gym and do everything they can in order to make sure the Gym Leader's sister, Marnie, becomes Champion. They even help the player sometime after they defeat their leader by helping them deal with the Macro Cosmos employees so that Victor/Gloria and Hop can get to Rose Tower where Chairman Rose and Leon are.
- Bare Your Midriff: Both male and female grunts wear shirts that cut off above their stomachs, showing off their navels. The males probably aren't intentionally doing so, though.
- Blow That Horn: The male grunts are frequently seen blowing their two-belled vuvuzelas, including immediately before battle.
- Broken Bridge: They act as inconvenient roadblocks a lot.
- Brought to You by the Letter "S": Y, in this case. In addition to the Y logo on their shirts (tilted 135 degrees counterclockwise), they've got Y-shaped two-belled vuvuzelas and Y-shaped covers for the giant safety pins on their backs.
- Dark Is Not Evil: They primarily use Dark-types - Galarian Zigzagoon, Nickit, Purrloin, and so on. Since their immediate superior is the region's Dark-type Gym Leader, this makes sense. Also, they're just really loud and disruptive, and by no means actually evil.
- Delinquent Hair: The male grunts have mohawks, the female grunts are shaved at the sides, and both of them are half-dyed pink.
- Fan Dumb: In-universe; They cause trouble for the other Gym Challengers just because they love Marnie so much, something that Marnie herself very much disapproves of.
- Fat Bastard: The male grunts are rather chubby.
- Football Hooligans: They're designed after them, being a fan club of Marnie turned street gang dedicated to sabotaging her rivals.
- Funny Background Event: When the player battles Marnie, they're there in the background, cheering her on.
- Good All Along: They may be harmless loudmouthed blowhards who like to cause trouble everywhere they go, but it turns out they're just Piers' Gym Trainers; they don't even really qualify as a villainous team. They even help the player and Hop help deal with the Macro Cosmos employees when Leon is suddenly called to Rose Tower the night before the Championship Cup Finals.
- Harmless Villain: Their "evil" deeds include things like being loud, challenging people at inopportune times (like everyone else in the Pokémon world) and setting up roadblocks on the wrong paths. For a lot of the game, the worst they ever get to is trying to steal one guy's bike (and even then they claim they were going to give the bike back). The one time they do achieve something legitimately problematic (their lockdown of Spikemuth), Marnie chews them out so thoroughly they pretty much stop being antagonistic from that point on.
- Interface Spoiler: Their connection to the Spikemuth Gym can be given away the moment the player tries to edit their online Trainer Card as the "Dark Gym" and "Team Yell" logos (which are both the same symbol rotated at a different angle) are both available as icons Though the game treats this connection as a Dull Surprise and their general lack of actual villainy ends up becoming a twist for both organizations.
- Loony Fan: The whole team is this to Marnie. They even carry banners with her image in them and also rush in out of nowhere to cheer her on during her battles, remaining in the background. While they do genuinely love Marnie and want her to be Champion, the "loony" part is a part of their disguise.
- Multicolored Hair: Half black, half pink.
- Paper-Thin Disguise: "Team Yell" are just a disguise donned by the Spikemuth Gym Trainers. When this is revealed the grunt lampshades that they think everyone already knows who they are anyway, making the disguises pointless.
- Pet the Dog: One encounter with them has them trying to keep others from waking a sleeping Silicobra up. They're also shown following and cheering on a Drednaw later on, with no means of harassing it either.
- The Quincy Punk: Themed after them as they're a typical depiction of British hooligans.
- Red and Black and Evil All Over: Well, hot pink and black, but you get the point.
- Red Herring: No, they aren't really evil. They only really play negatively into the game's actual story when they blockade Spikemuth Gym as part of their scheme...which is ultimately limited solely to ensuring Marnie becomes champion. After that, they actually help the player character in the main conflict.
- Sequel Escalation: Inverted. Like Team Skull, their "plans" don't involve destroying the world, targeting legendary Pokémon, and in fact they aren't even out to steal money, just make a ruckus that Marnie can exploit. And, as it turns out, they are actually just the Gym Trainers who serve under Piers, the Dark-type Gym Leader of Spikemuth and Marnie's brother, and all he wants is to step down from his position and let Marnie take over.
- Spikes of Villainy: Spiked anklets, spiked bracelets, spiked vuvuzela bells, and a nasty attitude.
- Villainy-Free Villain: While they do oppose Gym Challengers, they don't do anything illegal or really evil. At most they'll just block your path and battle you.
- Walking Spoiler: As shown by several of the tropes on this page, there's a bit more to this villain team than what you can tell at first glance.
- Well-Intentioned Extremist: Besides cheering for Marnie, shutting Spikemuth off to keep everyone but Marnie from fighting their Gym Leader was just a sign of their collective fear of their city descending further into obscurity and potential poverty due to their gym lacking a Power Spot. In the end Marnie still becomes a famous/popular enough trainer to improve Spikemuth's reputation.
Piers / Nezu (ネズ nezu)
The Leader of the Dark-type Gym in Spikemuth, where all of Team Yell are employed as the Gym Trainers.
