[[WMG: Ninten]]
A twelve-year-old American boy, who lives with his parents and twin younger sisters outside the town of Podunk ([[StealthPun Mother's]] Day). He sets out to find the Eight Melodies and possibly uncover secrets about his mysterious great-grandparents. Not much information is given about his personality, but he seems to be a kind, brave kid, if with a bit of a temper. He loves prime ribs, penguins, and baseball, and occasionally suffers from asthma.
* TheAce
* AdaptationDyeJob: Saori Kumi's novel switches Ana and Ninten's hair colors. It turns out that [[HairColorSpoiler there was a reason for that]] later on.
* AdaptationNameChange: He's known as "Ken" in the novelization.
* TheAllAmericanBoy: He's a bat-wielding {{Everyman}} boy from a small American town.
* BadassAdorable
* BatterUp: Uses baseball bats as weapons.
* BerserkButton: Lying about his mother calling him is not a smart move, hippies.
** Of course, he got mad when his sisters are attacked.
* BigBrotherInstinct: When his sisters are attacked the first few moments in game, he will endeavor to destroy whatever harms them to save them.
** KnightTemplarBigBrother
* CombatMedic: He has a powerful physical attack, the strongest of all permanent members, but all of his PSI is assist and healing. He doesn't even get a SignatureMove like Ness's PSI Rockin or Lucas's PK Love.
* [[invoked]]FountainOfExpies: His appearance (especially his trademark striped shirt) set the standard for ''MOTHER'' series protagonists.
** Ness is the most obvious example, as he is almost an exact copy of him. As Ness is more well-known, this sometimes leads to confusion, as they share the same outfit. Fans often draw Ninten wearing a red neckerchief and a red, white, and blue stripe pattern on his shirt to differentiate them, based on a live-action Japanese commercial for ''MOTHER''.
* TheHero
* HeroicMime: [[spoiler:Until the ending, at least in the English prototype]].
* HotBlooded
* JackOfAllStats: Contrasting Ness and Lucas in the sequels, Ninten isn't held back by a horrible Speed stat while still throwing around physical attacks just as hard, [[HandicappedBadass which is pretty impressive for an asthmatic]]. On the flip-side however, his massive PSI movepool is all support and no Offense-grade skills.
* JerkWithAHeartOfGold: The novelization written by Saori Kumi portrays him as this.
* MagicKnight: Has healing and shield PSI, with strong attack and good defense.
* NiceHat: The baseball cap that he convinced his dad to buy for him.
* OfficialCouple: Ninten and Ana are actually the only fully canon couple between the playable characters in the series, which is something most people forget.
* PrimaryColorChampion
* PsychicPowers
* ScarfOfAsskicking: The live-action commercial for the game has Ninten wearing a red neckerchief. Most fan artists tend to draw Ninten with this in order to help distinguish him from Ness.
* SensitiveGuyAndManlyMan: The Manly Man to Lloyd's Sensitive Guy. He becomes the Sensitive Guy when Teddy takes the latter's place.
* SupportPartyMember: Has only support/healing PSI, but is capable of powerful normal attacks.
* TrademarkFavoriteFood: Prime ribs.
* WhiteMage: Only has support and healing PSI.

[[WMG: [[SpellMyNameWithAnS Loid/Lloyd]]]]
The eleven-year-old boy genius from Merrysville (Thanksgiving). Loid is brilliant, but is often bullied by his classmates for being a nerd and a weakling. He developed a tendency to hide in trash cans to avoid confrontation. Despite this, he has a great deal of determination, even when it comes to the dreaded gym class. Bullying has left him very shy and cowardly when he joins Ninten, but over time he becomes stronger and more confident in himself. He likes rockets, science, computers, and ''{{Superman}}''.
* {{Badass|Adorable}} {{Adorkable}}
* BigDamnHeroes: [[spoiler: He saves Ninten, Ana, and Teddy from being slaughtered by the [[HopelessBossFight R7038]], but he is too late to save the critically-wounded Teddy. He still manages to destroy the R7038, however]].
* ButtMonkey: He gets bullied a lot at school, and everyone calls him a weakling.
* GadgeteerGenius
* HeroicAlbino: Never explicitly stated to be albino, however, fans like to portray him as this, given his white hair and poor eyesight.
* ItemCaddy
* LovableCoward: Ninten meets Loid hiding from bullies in a garbage can. He later gets over his cowardice through CharacterDevelopment.
* MeaningfulName: Loid's name comes from his Japanese name, "Roido," coming from the word "roidomegane", meaning "round glasses with thick plastic rims".
* NerdGlasses
* SensitiveGuyAndManlyMan: The Sensitive Guy to Ninten's Manly Man.
* TheSmartGuy
* SpellMyNameWithAnS: ''VideoGame/{{MOTHER|1}}'' translates his name as "Loid," but his sticker in ''VideoGame/SuperSmashBros Brawl'' calls him "Lloyd". Tomato's retranslation of ''MOTHER 1'' also gives him Lloyd as his default name.
* YouthfulFreckles

[[WMG: Ana]]
The only permanent female member of the group, Ana is a twelve-year-old from Snowman. A sweet, but timid girl, Ana has never ventured out of Snowman alone. She is described as kind at heart, with a great sense of direction. Before the start of the adventure, Ana was unable to sleep due to odd dreams, and sets out with Ninten in hopes of finding her abducted mother. [[AllThereInTheManual She is deeply religious (one of her favorite possessions being a Bible), is a skilled piano player, and also collects stamps and envelopes]].
* AdaptationDyeJob: She's a brunette in the novelization.
* BadassAdorable: This adorable little girl in pink and pigtails has some powerful PSI.
* TheChick
* FriendToAllLivingThings: A lover of all animals, [[FreeTheFrogs she once released all the frogs set to be dissected at her school]] with her ''mind''.
* GirlishPigtails: Only with her [[NiceHat hat]] off. When it's on, she has a single ponytail.
* TheIngenue
* LittleMissBadass
* MissingMom: One of the big reasons she offers to join [[TheHero Ninten]] is to find her mother.
* NiceHat
* PsychicPowers
* RedMage: Her support and healing PSI is even better than Ninten's, and she's the only offensive PSI user in the party.
* SpoiledSweet
* SquishyWizard: [[GlassCannon Boy, is she ever]].
* WhiteMagicianGirl: Subverted. She has the typical personality of one, but is actually a RedMage.

[[WMG: Teddy]]
Unlike the other members of the party, Teddy is not a kid; rather, he is a young man in his late teens to twenties. Leader of the B.B. (Black Blood Gang), he is the kingpin of the town of Ellay (Valentine) until some kids came in and started messing with his crew. [[DefeatMeansFriendship After he is beaten by Ninten, he joins the party to avenge the death of his parents.]] He likes smoking, fighting, and rock and roll.
* TheAlcoholic: The [[AllThereInTheManual MOTHER Encyclopedia]] implies that Teddy is this.
* {{Badass}}
** PopCulturedBadass
* TheBigGuy
* CoolShades / TriangleShades: He was doing [[TengenToppaGurrenLagann Kamina's shades]] over a decade before Kamina ([[Anime/{{Pokemon}} or Squirtle]]).
* DefeatMeansFriendship
* [[{{Delinquents}} Delinquent]]
** [[GreaserDelinquents Greaser Delinquent]]
* [[spoiler: GuestStarPartyMember]]
* FanNickname: Jack, which didn't last long once the official translation was discovered.
* LightningBruiser
* [[spoiler: PlotlineDeath: Only in the original Japanese version. In the translated prototype and the ''MOTHER 1 + 2'' GBA port, he is shown recovering in a hospital.]]
** [[spoiler: SparedByTheAdaptation]]
* SensitiveGuyAndManlyMan: The Manly Man to Ninten's Sensitive Guy.
* SmokingIsCool: It is said that Teddy smokes [[GettingCrapPastTheRadar "Horse Shit" brand cigarettes]] in the [[AllThereInTheManual MOTHER Encyclopedia]].
* UsedToBeASweetKid: A NPC will tell you that, before his parents' deaths, he was a very nice boy.
* YouKilledMyFather: His parents were supposedly killed by wild animals on Mt. Itoi, and he joined Ninten in order to avenge them. [[spoiler: The MOTHER Encyclopedia says that it was actually a car accident, but he refused to pay attention to this finding.]]



[[WMG: Pippi Lindgren]]
A pigtailed young girl whom Ninten must save from zombies.
* ActionGirl
* BadassAdorable
* BrainwashedAndCrazy: [[WhatCouldHaveBeen Unused data]] suggests you would have had to fight a zombified Pippi before she joined you.
* CuteBruiser: You wouldn't expect her to have ''the exact same stat growths as Teddy''.
** If you realize she's Literature/PippiLongstocking, then yes, yes you would.
* FieryRedhead: In a good way.
* GirlishPigtails
* GuestStarPartyMember
** CrutchCharacter: Though she does turn an unintended encounter group location into a PeninsulaOfPowerLeveling.
* LawyerFriendlyCameo: Of Literature/PippiLongstocking. Her last name is also the same as the author of the ''Pippi Longstocking'' books, Astrid Lindgren.
* LightningBruiser
* LittleMissBadass
* LittleMissSnarker
* PintsizedPowerhouse
* PrecociousCrush: She's 7 years old, and they way she talks to the 12-year old Ninten, it's clear she has a thing for him.
* RhymesOnADime: Her quote in the Mother Encyclopedia rhymes, and note that it was ''after it was translated to English that it rhymed.''
-->''"I'm Pippi. Who're you? What is it you're up to? I'm off on an adventure every day. Don't think of me as boyish, OK?"''
* SuperStrongChild
* YouthfulFreckles

[[WMG: Ninten's Family]]
Ninten has a Mother, a Father and two sisters, Mimmie and Minnie. Much like Ness's family, Minnie can store items, and Ninten's dad is only spoken to over the telephone.
* AddressingThePlayer
* TheFaceless: Dad, [[spoiler: though we at least see ''some'' of him in the translated ending]]
* [[spoiler: SequelHook]]: Though it never goes anywhere.
* TraumaInn: Mom's function.
* UnnamedParent
* WhatHappenedToTheMouse: Just what was that "something" that [[spoiler: Ninten's dad was fretting over at the end of the game]]?

[[WMG: Queen Mary / [[spoiler:Maria]] ]]
The ethereal, beautiful queen of the mysterious land of Magicant. She has fallen gravely ill, and the only thing that will restore her to her former self are the Eight Melodies. [[spoiler:She is Ninten's great-grandmother, and was the deeply-beloved foster mother of Giygas.]]
* TheHighQueen
* [[spoiler:[[LukeIAmYourFather Ninten, I Am Your Great-Grandmother]]]]: [[spoiler:She is Ninten's great-grandmother, who disappeared a long time ago and has been trapped in her own mental world ever since.]]
* [[spoiler: PosthumousCharacter]]: Technically.
* PrincessesPreferPink: Or queens, anyway.
* [[spoiler: StockholmSyndrome]]
* WalkingSpoiler

[[WMG: George]]
Mentioned only in the prologue and at the end of the game, [[spoiler: he is the reason for the alien invasion, as he stole the secret of PSI from Giygas's species. He is the husband of Maria and the great-grandfather of Ninten.]]

* [[spoiler: TheAtoner]]: Does his best to protect Ninten from [[spoiler: the consequences of his actions.]]
* CameBackWrong: [[AllThereInTheManual Was the most popular guy in town before the abduction]], but when he escaped, he sealed both his doors and his mouth shut, and [[BerserkButton blew his top]] whenever Maria was mentioned.
* GadgeteerGenius: [[spoiler: He built EVE.]] This is particularly impressive since he lived before there was even the concept of a robot. [[JustifiedTrope He must have learned a lot from the aliens.]]
* PosthumousCharacter: Though it is never seen nor mentioned how he died.
* [[spoiler: UnwittingInstigatorOfDoom]]: If you think about it, [[spoiler: he is responsible for every negative event of the entire series]]. He does not live to see any of this.
* WalkingSpoiler



[[WMG: [[SpellMyNameWithAnS Giegue/Gyiyg/Giygas]]]]
The grim leader of the invading alien forces. [[spoiler:He leads the invasion to take revenge for the human theft of his race's PSI technology, but his resolve crumbles when confronted with the memory of his beloved foster mother, and swears to come back to finish the job later.]]
* AntiVillain
* BigBad
* DisproportionateRetribution
* {{Expy}}: Mewtwo of ''{{Pokemon}}'' was based on his design, and depending on the ''Pokémon'' canon in question other similarities crop up. Which makes sense since the creators of the Mother series (at least this and the second one) APE inc. went on to become Creatures inc. and created the Pokemon series.
* GalacticConqueror
* TheGreys
* HumansThroughAlienEyes
* IJustWantToHaveFriends: Feeling [[EvenBadMenLoveTheirMamas hurt over the loss of Maria]], he now desperately wants Ninten to join him.
* KillAllHumans: It soon becomes apparent that he has forsaken love from humans entirely, which is seen during the confrontation with Ninten and friends:
-->''"Ninten! I am grateful to your family. Your Great-Grandparents, George and Maria, raised me when I was very young. But, George stole vital information from our planet that can be used to betray my people... And now, one of his descendants is obstructing our plans, and must be stopped!! Ninten! I am talking about you! Go home now! Perish with the rest of the ugly Earth People. Foolish one, you cannot do a thing with your meager powers... Powers worthy of a lowly insect. Ninten! You alone, I may save you. Just you alone. Board our Mother Ship with me."''
* LoveMakesYouEvil
* MySpeciesDothProtestTooMuch: Giygas' race abducted Maria and her husband George. The alien himself was raised from infancy by them. During this time, George studied the alien's PSI powers without their permission, culminating with their escape back to Earth. Once he matured, Giygas was tasked by his people to ensure that PSI never spread onto Earth. However, Giygas did not want to betray those who raised him. In the end, he was forced to [[IDidWhatIHadToDo detach himself from Maria and begin preparations for the invasion of Earth]].
* NighInvulnerability: He cannot be defeated with force or with weaponry. Only reminding him [[ThePowerOfLove that his human adoptive mother loved him can damage him mentally]].
* SpellMyNameWithAnS: Depending on the translation, his name came up as: Giegue in the original NES Earth Bound (Zero) prototype, Gyiyg in Japan and in Videogame/EarthBound and Starmen.net's Fan Translation as [[MyNaymeIs Giygas]].
* StartOfDarkness: His role here lay the foundation for what he became in ''Videogame/EarthBound''. Ninten rejecting his offers of companionship, coupled with his memories of his adoptive human mother used against him, tore Giygas up inside, until by Mother 2/Earthbound [[EldritchAbomination there's nothing left]].
* [[TalkingTheMonsterToDeath Singing the Alien to Death]]
* TragicMonster: Especially once you learn what happens to him later...
* UsedToBeASweetKid: Maria grew to love the young Giygas as if he were her own child. She said that he was always wagging his tail, and would only stop whenever she sang her lullabies.
* WalkingSpoiler: At least in this game. [[ItWasHisSled Not that anyone cares.]]
* WeWillMeetAgain: He vows to return to Ninten. Except he doesn't. [[WhatCouldHaveBeen There is no direct sequel to this encounter]].
* YouCannotGraspTheTrueForm: Even before his trope-naming sequel appearance.
-->"The form of Giegue's attack was inexplicable!"
* YouWillBeSpared: He's willing to spare Ninten due to being indebted to his great grandmother.
