Heroinetchi, originally Madonnatchi (マドンナっち Madonnatchi) in Japan, is a female adult-stage Tamagotchi who debuted in the Tamagotchi! anime in Japan, serving as a minor antagonist.
Though her virtual pet debut was on the Tamagotchi iD L in Japan, her full international debut was not until the release of Tamagotchi Plaza, where she was renamed "Heroinetchi".
Name Origin[]
Her Japanese name comes from the Italian term "prima donna", which may mean a chief female opera singer, or a temperamental person with an inflated view of themselves. This reflects in both her profession and personality.
Her English name comes from the word "heroine", referring to a female protagonist or hero in a story. This likely refers to how she sees herself, acting as though she deserves the role of the "main character" and star-of-the-show, which can be seen as ironic seeing as she frequently antagonizes others out of jealousy. It also reflects her relationship with her brother, Herotchi, whose name uses the masculine or neutral form of the word, being "hero".
Appearance[]
Heroinetchi is generally humanoid, with a pink head and arms, white hair with ear nubs similar to Mametchi's at the top and a white, layered dress. Her stockings are also white, and she has two pink ribbons in her hair. Her eyes are shiny, with a big highlight and a diamond-shaped sparkle in each. In her anime appearance, she has a streak of blue around the bottom of her eyes.
Personality[]
Heroinetchi dreams of one day being the next big actress on TV. Unfortunately, she has a nasty mean streak whenever things don't go her way. Because of this, she's always undermining herself.
Heroinetchi and her uncontrollable anger
In the anime, Heroinetchi acts bratty and thinks she should get everything she wants. She also has uncontrollable anger, and is often bossing her brother, Herotchi, around. If he doesn't do what she says, she normally screams and shouts at him to do it right. When she is around other Tamagotchis besides her brother, she tries to act very cute and sweet to get them to listen to her, whether or not she likes them.
Heroinetchi hates and is jealous of Lovelin, and tries to get rid of her so that she can be the new Tamagotchi idol of TAMAX-TV. She normally tells Herotchi to set up traps for Lovelin, and he also sets up traps for Gotchiman because he wants to be the new hero of TAMAX-TV.

In the Anime[]
Tamagotchi![]
Heroinetchi is an actress at TAMAX-TV, and appears on the GOTCHIMAN TV Show, along with Gotchiman, Heroine Lovelin and her brother, Herotchi. Usually she has to be rescued from the Black Hat.
With her brother, Herotchi
She made a cameo in "New Members? To Class Suddenly" appearing on TV and officially debuted with Herotchi in "Hero? Idol? Revealed at TAMAX-TV". She schemes with him and later on, Herotchi puts weights in Gotchiman's boots and sets up a booby trap that will drop an embarrassing wig on Lovelin. However, it backfires when the trap activates on Heroinetchi instead and humiliates her in front of the TV crew.
After learning that Anpan Detective and Gotchiman will star in a show together in "Dream Co-star? Gotchiman vs Detective Anpan", Heroinetchi and Herotchi scheme to ruin the collab in fear of Anpan Detective being more popular than them. Herotchi vandalizes Gotchiman's car while Heroinetchi vandalizes Hero Lovelin's dress. However, this has no effect as those props weren't being used so they trick a Gotchiman script writer to add in ridiculous ideas to ruin the episode instead. They later find out that that Gotchiman and Anpan Detective are co-starring in a quiz show instead of the Gotchiman show meaning their trick had no effect again. Black Hat then vandalizes a nearby set with explosive hats, having read the messed with script, causing it to fall down and crush Herotchi. A hat also falls onto Heroinetchi's head and explodes on her.
In "Tomomi's TAMAX-TV Debut!?" the two become jealous of Tomomi's new popularity and Heroinetchi has Herotchi mess with her microphone. While Tomomi's voice is messed with, Lovelin pretends its part of the show and the audience believes her. Heroinetchi and Herotchi are then attacked by pigeons from Tomomi's last magic trick. In "Lovelin Shock! Manenetchi's Change of Heart?", Heroinetchi begs Manenetchi to manage her after her own manager gets sick, believing that Lovelin's popularity comes from her management skills. This causes Lovelin to become sad as she thinks that Manenetchi won't work with her anymore, but the two become closer after Herotchi's sabotage puts Manenetchi in danger.
Heroinetchi and Herotchi try to sabotage Lovelin and Gotchiman again in "Nahahaha! Mametchi's GOTCHIMAN Debut". However, Heroinetchi is frightened by a snake Herotchi places on the set and unknowingly swings on a vine he loosened earlier. She nearly falls into a river before Lovelin catches her. In "Fashion! The Best? Eggs of Style", Heroinetchi and Herotchi are affected by the Eggification curse. Despite being turned into eggs, they still perform their roles on the GOTCHIMAN show.
GO-GO Tamagotchi![]
In GO-GO Tamagotchi!, Heroinetchi is also shown to be jealous of Yumemitchi and Kiraritchi. She schemes with Herotchi in "Dokidoki! Audition Soon" to make them fail their audition for a new TV show by ruining their outfits. Herotchi manages to shrink their outfits along with Heroinetchi's dress, ruining her chance at the audition.
