- Alien Animals: Many Tamagotchi characters that resemble Earth species (such as Pochitchi, who resembles a dog) can be mistaken for their Earth counterparts.
- Animate Inanimate Object: A lot of the Tamagotchi characters also fall under this, such as Crackertchi (a party cracker), Yakantchi (a tea kettle), Mousetchi (a computer mouse), Belltchi (a bell), and Shelltchi (a clam shell).
- Anthropomorphic Food: Several Tamagotchi characters resemble Earth food, including mochi, hamburgers, acorns, and more.
- Bizarre Alien Biology: Tamagotchis come in all weird shapes and forms, from round balls, to being a talking wine glass, to being a washiki toilet with a giant poo and then an actual sentient giant wad of poo. However, they all eat, communicate, marry and produce offspring with no trouble at all.
- Black Bead Eyes: Several characters, mostly the ones introduced in the original 90's toys.
- Blush Sticker: Quite a few characters have permanent blush stickers.
- Cast Herd: Tamagotchis are broken up into several subspecies: angels, devils, bugs (Mushitchi), fish (Sakanatchi), Akai Tamagotchi, Ura Tamagotchi, My Tamas, Tama Pets, and living entities (Gaiatchi).
- Cheated Angle: Tamagotchi with beaks or muzzles tend to be drawn "Picasso style" when seen from the side so that the shape of the beak remains the same.
- Descriptively-Named Species: The "outsiders naming them" variety; Professor Banzo and Mikachu named each species as they discovered them, naming them after Earth culture and objects. After returning to their planet, the Tamagotchis adapted the naming conventions and language.
- Dub Name Change: Some characters' names are changed when the toys are translated. Some of them are simple translations (for example, "Futagotenshi" becomes "Twin Angels"), while others are for censorship (for example, "Bombtchi" became "Bakutchi").
- Fantastic Naming Convention: All the Tamagotchi species end in "tchi". Angels, Deviltchi, Akai Tamagotchis, and Ura Tamagotchis have their own conventions as well.
- Four-Temperament Ensemble:
- Sanguine - Kuchipatchi
- Choleric - Memetchi
- Melancholic - Lovelitchi
- Phlegmatic - Mametchi.
- Freudian Trio: The main characters (besides Lovelitchi)
- Mametchi is the Superego, he is easily the most intelligent of the group and is nice to most people he meets.
- Memetchi is the Id, she is the most emotional of the group and tends to be a crybaby. (Ego sometimes).
- Kuchipatchi is the Ego, he is typically nice and friendly, but he has many Cloudcuckoolander moments. (Id sometimes).
- Fingerless Hands: Most Tamagotchis have stubby hands, though they will spontaneously produce visible fingers in certain cases to perform specific actions (such as giving a thumbs up, for example).
- Gender Equals Breed: The Mesutchi and Osutchi played this straight, with only the baby and child stage characters looking alike. In the 2000-era toys, it's primarily used for the babies, but later versions made some gender-neutral breeds into gender-exclusive. For example, Mametchi was neutral from V1 through V3, but exclusively male from the Entama/V4 onward.
- Hot Skitty-on-Wailord Action: Tamagotchi marriage can result in this.
- Innocent Aliens: The majority of Tamagotchi breeds are friendly, and at worst nuisances that can't do much harm. Their primary interest in Earth is to learn about it and befriend humanity, and only originally came to it in the first place to seek refuge from their intoxicated planet.
- Humanoid Aliens: Initially, Tamagotchis weren't very human with minor exceptions. But more human-like Tamagotchi species have appeared since they visited Earth.
- Loads and Loads of Characters: Each new toy introduces a number of new characters. According to the Wiki, there are over 1,000 different documented Tamagotchi characters.
- The Noseless: While there are certain Tamagotchis who have visible noses, they're a minority compared to the characters who don't have visible noses.
- Only One Name: Most characters. There is at least one exception, though (Makiko, for some reason, has an actual human name - Madeleine Kirie Dotchine).
- Patchwork Kids: The primary gimmick of the Tamagotchi m!x and Tamagotchi On, where if you marry your Tamagotchi with another, it will have a child with a random mixture of features from both of its parents (e.g. it could have the body of its mother and the facial features of its father). The combination of traits becomes more random with each generation.
- Plant Aliens: Some Tamagotchi are based on plants, with Kusatchi (a flower Tamagotchi in a flower pot) as one of the earliest examples.
- Ridiculously Cute Critter:
- Most modern characters tend to have massive heads and big eyes, stubby limbs, and other features that give them overall adorable appearances.
- On the original virtual pets, how cute the Tamagotchi became was determined by how well they were cared for; severely neglecting a Tamagotchi would result in one that was ugly and had a short life span.
- Secret Character: A number of releases contain these, often requiring to raise the Tamagotchi in unusual ways to obtain them. Others require using rare items, feeding certain foods, or connecting to other Tamagotchis.
- Soap Opera Rapid Aging Syndrome: Chamametchi, Kikitchi, and several other teen characters were popular enough with the target demographic that Bandai bumped them up to adults, so that the kids could play with the character longer. Though now this means Chamametchi, who is a very young girl who always has her panties showing, can marry and have children.
- Talking Poo: Lucky Unchi-kun and Super Unchi-kun.
- Temporary Online Content: Several characters were only available to raise or marry:
- On the Entama and Uratama, the special dating cards necessary to raise the secret Hatena and Bikkuri characters were only available through an arcade game. Thankfully, third party software exists to generate the codes needed to unlock them.
- Dreamitchi and Dazzilitchi, the two secret characters of the Music Star, were only available to players who buy their respective evolution items from the Music Star site, which is no longer online.
- The Tamagotchi m!x and Meets have marriage partners that are exclusive to stations, which are scattered around various stores in Japan and cycle through different characters depending on the season. The Meets/On also features special marriage partners that are exclusive to the tie-in app, which change every month.
- Theme Naming: Most characters have names ending in "-tchi".
- Trademark Favorite Food: On modern versions, many characters have food likes and dislikes. For example, Kuchipatchi's favorite food on the Version 2 is corn.
- Two Guys and a Girl: Before Lovelitchi became represented as a mascot of the series, the group of mascots had Mametchi and Kuchipatchi as the two guys and Memetchi as the girl.
- Verbal Tic: A number of character punctuate sentences with one, so much as that there's a page for them.
- Debut: Tamagotchi Generation 1 (1996)
One of the first characters introduced and the protagonist of the anime series. Mametchi is a brilliant, friendly Tamagotchi that lives in Mame City with his parents and little sister. He loves science and is interested in robotics.
- Adorkable: He's always geeking out over something scientific and a little awkward, and he's adorable.
- Always Someone Better: Kuromametchi is more charismatic and charming, while Righttchi is better at robotics.
- Badass Adorable: He's helped save the Tamagotchi Planet many times, and is incredibly cute.
- Big Brother Instinct: Was saving his little sister's life even before she hatched.
- Big Brother Mentor: To his little sister, Chamametchi, who idolizes him.
- Break the Cutie: Nearly the entirety of the first season of Tamagotchi! Yume Kira Dream is this. He's stuck living in an unfamiliar city with a mentor that doesn't care about him, and is attending a school where he finds there are students far more advanced in robotics than him. He handles it pretty well until he loses the tea robot competition to Righttchi. An argument with Ikaritchi later that night finally breaks him to the point where he tries to run away home to Tamagotchi Town.
- Breakout Character: Went from just one face within hundreds of characters to becoming the series mascot.
- Calling the Old Man Out: In Yume Kira Dream, he calls Ikaritchi out his reclusive, uncaring nature, and ends up dropping Ikaritchi's boat into the sea.
- Character Development: In Let's Go! Tamagotchi, Mametchi is portrayed as more energetic and somewhat of a Large Ham. He's somewhat less energetic in the TV anime, but still has a cheerful attitude.
- Chaste Hero: He's completely oblivious to the fact that Himespetchi has a huge crush on him, much to her dismay.
- Child Prodigy: In the virtual pets, he's considered an adult breed, but he's a young kid in the TV show. In both cases, he's characterized by having an IQ of 250, and in the TV show he's often seen making inventions at home and goes on to take the Robotics class at Dream School in the Yume Kira Dream arc.
- Childhood Friends: With Memetchi and Kuchipatchi.
- Disney Death: He and Tanpopo are swallowed by Blackholetchi, but they're later saved when Blackholetchi finally wakes up.
- Dreadful Musician: So terrible at singing that one attempt caused Himespetchi's ship to crash. Luckily for everyone, Papapianitchi fixes this.
- Early Installment Character Design Difference: In the North American releases of the 90's toys, he was a blue-colored female rather than a yellow-colored male like he is now.
- Face Your Fears: Mametchi ends up having to face his fear of the dark in the first movie.
- Friend to All Children: Is not only a really good big brother to Chamametchi, but has also had several positive interactions with Lovesoratchi as shown in GO-GO Tamagotchi!. Also, episode 131 revolves around him taking care of a large baby bird-like Tamagotchi named Fuwamokotchi.
- Friendly Rivalry: With Kuromametchi.
- Four-Temperament Ensemble: Phlegmatic.
- Gadgeteer Genius: He loves to make his own pieces of technology and is often shown inventing something in his room.
- Gender Flip: Mametchi was a female in the American releases of the 90's toys before being changed to a male later on. Averted in Japan, as he was always a male for the Japanese releases.
- The Hero: Of both of the films and the anime.
- Hollywood Tone-Deaf: He is shown to be very bad at singing. Until episode 26 of Yume Kira Dream, that is, where he learns how to sing properly.
- Improbably High I.Q.: His is measured at 250. May be justified as his IQ is measured among other Tamagotchis, not humans.
- It's All My Fault: In The Movie, when he finds out that Sunnytchi left the Tamagotchi Planet.
- Large Ham: Definitely not as loud as most examples of this trope, but he has his moments in the Let's Go Tamagotchi.
- Nice Guy: One the nicest members of the cast.
- Nice Job Breaking It, Hero!: In The Movie, he develops his own portable sun. The following day, Sunnytchi leaves the Planet.
- Nice Mean And In Between: The nice to Memetchi's mean to Kuchipatchi's in-between, Mametchi is one of the nicest characters on the show and a great brother to Chamametchi.
- Oblivious to Love: He can't seem to grasp the concept or realize when girls are flirting with him, to Himespetchi's dismay.
- Off-Model: For a long time, the LCD toys depicted him with Black Bead Eyes rather than the almond-shaped eyes he has in official artwork. This has since been corrected.
- Primal Fear: He's terrified of the dark.
- Red Oni, Blue Oni: He's the level-headed Blue Oni to Memetchi's emotional red oni. (With Kuchipatchi in between)
- Rude Hero, Nice Sidekick: Inverted. Mametchi's an exceptional protagonist, but there's several instances in the TV anime where he takes the back seat in favor of the respective saga's female protagonists. Even then, he's not rude by any means, but he doesn't shine nearly as bright as he does when he's given the lead role.
- Secret Keeper: Keeps Lovelitchi's identity of Lovelin a secret until she reveals herself to everyone at school.
- The Spock: Fits this role, Mametchi is the most intelligent member of the tiro, and is also level-headed and supportive.
- Series Mascot: Gradually became this after the brand rebooted in 2004.
- She's a Man in Japan: While he was always male in Japan, the initial wave of Tamagotchi toys in America made him a female. Later incarnations of the series released in America switch his gender.
- Ship Tease: Even though Mametchi doesn't seem to fully grasp romance, he has had moments of this nature with some of his female Tama-Friends.
- Despite not taking any hints from Himespetchi's obvious crush on him, he doesn't hesitate going on a ferris wheel with her in episode 126 or seeing fireworks with her in Yume Kira Dream's 35th episode. He also makes a dance offer to Himespetchi only in GO-GO Tamagotchi! episode 30.
- Lovelitchi and Mametchi are on excellent terms and have shared a ton of screentime even after Melodytchi came along. Lovelitchi was involved in the organization of at least three birthday parties for Mametchi (6b, 56a, and Yume Kira Dream 10), and Mametchi willingly put the first of these parties on hold for the entire day waiting for Lovelitchi to show up. They were also the first to hold hands while trying to eliminate the egg curse in episode 143.
- When Cafe Mama agreed to be Mametchi's homestay guardian following Yume Kira Dream episode 22, this meant living in Music Cafe with Pianitchi. As shown through the remainder of Yume Kira Dream as well Miracle Friends, they make pretty good housemates and get along very well, and in the episode beforehand (Pianitchi's debut episode), they worked together to figure out Ikaritchi's aloofness.
- Significant Birth Date: Mametchi's birthday is November 23rd, the same day the original Tamagotchi toys were first sold in Japan in 1996.
- The Smart Guy: He has an IQ of 250.
- Smart People Build Robots: When he joins Dream School, he majors in Robotics.
- Token Good Teammate: Among the trio, He is the least antagonistic.
- "Well Done, Son!" Guy: Not to his own father, but to his homestay parent, Ikaritchi, in Yume Kira Dream. Finally does earn his respect in episode 22, just before Ikaritchi leaves.

- Adaptational Jerkass: While she has always been selfish, the anime version of her is more bossy, resentful, and spoiled than her video game self, this is best seen in "The Power Of Gossip!".
- Berserk Button: Mess with her hair curl at your own risk. (Weirdly enough, in The Movie, when Tanpopo stretches Memetchi's hair after seeing the Tamagotchi world for the first time, she doesn't press this berserk button.)

- Follow Your Nose: He does this in GO-GO Tamagotchi! episode 11 to find Yumemitchi and Kiraritchi's missing clothes. He detours to the cafeteria first, naturally.

- The Kirk: He is not as intelligent as Mametchi, but he is more level-headed than Memetchi.

- Meaningful Name: "Mirai" is Japanese for "future". The twins are both from the future, hence one of them being named Miraitchi.

- Satellite Love Interest: Inverted. While she does have other character traits, Himespetchi is mostly identified by her crush on Mametchi and some of her other characteristics wind up helping her to drive the message home even further (e.g. she shows an interest in robotics and takes the Robotics class in Dream School... to be with Mametchi, who is also in that class).
