History WesternAnimation / MutantLeague

* NoPartyLikeADonnerParty: One episode had the players stranded in the mountains after a plane crash; as Bones set off to find help, the other players started to turn on the reptilian Razor Kid as, apparently, lizards are high in protein. Thanks to his agent, however, Razor only has to give up his tail (which can grow back). When the incident is brought up in another episode, one of the players claims the tail [[TastesLikeChicken tasted like chicken]].

* AffirmativeActionGirl: The second season introduced us to Thrasher Malone, the show's first female mutant. Even moreso with the plot of her introduction episode being about [[StayInTheKitchen the evils of sexism]]. Note that both sides have a point, and that male norms are in general physically stronger than female norms. There may be less gender dimorphic physical strength difference between male and female mutants. Thrasher proves herself before the gender reveal and joins The Monsters out of merit and not for affirmative action.

->'''K.T. Slayer''': Hey, kid. Yeah, you! Never wear anything but Spikeys, or I'm coming after ya. For real! (''screams and attacks the camera'')

* WrestlerOfBeasts: While nearly ''everybody'' on this show might qualify depending on your definition, especially since the show adds wrestling to the League's card, Zalgor's shown wrestling alligators to stay in shape in a couple episodes.

* SeriesContinuityError: Joe Magician is still seen playing sometimes in the second season. Even after the episode all about how he has to retire because he's getting older and there's only so much punishment even a mutant can take.

* AbusiveAdvertising: The faux commercial the show begins on.

* YourHeadASplode: The unfortunate side effect of a machine in one episode that makes players super-strong. Not that it's worse than anything else that happens to the mutants, mind.

* KarmaHoudini: Despite being called "evil personified" and the second season seeming as if it's building up to his deeds being exposed, Zalgor Prig never faces any consequences more serious than the humiliation of losing a one-on-one basketball game when he enters the stadium himself.

* MerchandiseDriven: Besides it being on a pair of video games, there was an almost-unknown line of action figures released based on the show.

* SeriesContinuityError: Joe Magician is still seen playing sometimes in the second season, even after the episode all about how he has to retire because he's getting older and there's only so much punishment even a mutant can take.

* SuddenlyAlwaysKnewThat: Sure, playing in the Mutant League would involve a certain level of fighting skill. It's still kind of jarring when there's a mid-second season episode about a bunch of characters being invited to a martial arts tournament.

* AnAesop: The general one for the show was "play fair and have integrity". A lot of second season episodes were built around one, like, don't be sexist, stay away from drugs, etc. There were also some that were unusually sophisticated for a cartoon meant for a younger audience (believe it or not), like know when it's time to stop doing something, your heroes aren't always who they appear to be, sometimes there's a situation with no ideal resolution, or the dangers of gambling or obsessive stalkers.

* AffirmativeActionGirl: The second season introduced us to Thrasher Malone, the show's first female mutant. Even moreso with the plot of her introduction episode being about [[StayInTheKitchen the evils of sexism]].

* BrokenAesop: In one episode, evil mutants try to trick some adolescent fans into jumping into toxic waste to mutate themselves and be more like their idols in the League. The kids hesitate because "norms can't mutate". The very existence of the Mutant League is proof that isn't true. Everyone in it--from the players, refs, coaches, team owners, play-by-play guy and various mutants who had nothing to do with the League--''were'' ordinary humans once upon a time. Trying to mutate yourself wouldn't be an easy or smart thing to do, sure. But obviously it can be done. Almost ends up being an example of DoNotDoThisCoolThing.

* FantasticRacism: A TwoPartEpisode is about a mutant-hating bigot being mutated, playing for the League for a while because his former friends have obviously turned on him, and seeing how mutants are still just people underneath.

* StoryArc: Both seasons have events from one episode lead into the next sometimes, but moreso in the second one, especially with how a lot of it builds up to the championship game.

* AnguishedDeclarationOfLove: A rather rare case for a merchandise-driven show of this nature. Sherry does this to Bones just as he’s about to [[spoiler: go underground to find his father and Razor in Prigg’s slave mine.]]

* SeriesContinuityError: Joe Magician is still seen playing sometimes in the second season, even after the episode all about how he has to retire because he's getting up in years and there's only so much punishment even a mutant can take.

* StalkerWithACrush: An episode is about Thrasher being imprisoned by a deranged fan who thinks she'd be his perfect wife.

* AnAesop: The general one for the show was "play fair and have integrity". A lot of second season episodes were built around one, like, don't be sexist, stay away from drugs, etc. There were also some that were unusually sophisticated for a cartoon, like know when it's time to stop doing something, your heroes aren't always who they appear to be, sometimes there's a situation with no ideal resolution, or the dangers of gambling or obsessive stalkers.

* ScrewTheRulesIMakeThem: The championship game has Zalgor pulling dirty trick after dirty trick to ensure his team wins. When they fail and his team loses anyway, he institutes a new rule that the last remaining player has to win a sudden death match with him to take home the trophy.

* ParodyCommercial: With the main characters being pro athletes, it isn't surprising a few plot beats were about them shilling shoes, cars, drinks, fast food, and even perfume in a late-series one. Heck, literally the first thing the viewer sees after the intro in the first episode is one.

* FantasticRacism: A TwoPartEpisode is about a mutant-hating bigot being mutated, playing for the League for a while because his former friends have obviously turned on him, and seeing how mutants are no different past the SuperStrength and all.

* ShesGotLegs: Or rather calves. Courtesy of [[IntrepidReporter Sherry Steele]] throughout the series.

* LosingYourHead: Happens to the characters sometimes, but usually they can just jam it back on and keep going. A couple of especially notable examples are a retired player who has to keep his head screwed on or it'll fall off, and a rule in the Mutant League version of some sports that if a scoring shot decapitates the goalkeeper, it's worth another point.
