- 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.
- 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.
- 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.
- 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 and still in diapers, 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 exclusive to stations, which are scattered around various stores in Japan and cycle through different characters depending on the season. The Meets and On also feature 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.
- Verbal Tic: A number of character punctuate sentences with one, so much as that there's a page for them.
