Ironmouse has used a phenomenal number of different VTuber models, and commissions new ones at a pace far greater than is typical. Several models also have variant costumes or forms. In addition to her primary streaming models, she has used various others, including models gifted by fans, joke models, or promotional models.
Canonically, each model represents Ironmouse from a different timeline, the stories of which are referred to as separate "Seasons." Ironmouse typically uses her most recent Live2D model when streaming, but prior models continue to make appearances. A Ironmouse model index was created by TheGyroscopicTree which contains all her models.
Ironmouse's original avatar, a free FaceRig model based on the VOICEROID+ model Tohoku Kiritan. Mousey reportedly downloaded it from the Steam Workshop page, where it was used as one of her earliest models. This period of using non-bespoke models is retroactively referred to as the Lost Season.
Canonically, this version of Ironmouse, known as "Baby Mouse," lives in Universe 000. She lost her memories, and became trapped in another person's body. She was able to jump from body to body, but not take an original form.
Ironmouse's first custom Live2D model, which she designed herself. Ironmouse favors asymmetrical design. This model was featured in a famous clip where she reached a $2,000 donation goal more quickly than she could explain why. It was modeled by Ketama, the same as her original Kiritan model. Several variants were later added, including a long hair mod in January 2021.
Canonically, Season 1 Ironmouse lives in Universe 111. Mousey entered the human world, but her unstable power kept causing problems with her original form. In this world, she never returned to Hell, and her demon attendant Bubi remained in Hell. Instead, she found VShojo and lives out her life as a VTuber.
Second 2D model. Also based on a design by Ironmouse, with new art by Nia. It was used throughout 2021, and received a number of variant outfits. Canonically killed off.
Canonically located in Universe 222. This Ironmouse lived in the human world for a long time, but periodically returned to Hell, with the result that the Wi-Fi was more stable down there. Bubi came from Hell to our world to watch over Ironmouse, protect her, and have fun with her. With Bubi's help, she found VShojo and became a VTuber to supply herself with soul energy.
Both the winter blue and Christmas red variants come with a little Bubi doll that she can hold in her arms. The models are also equipped with switchable capes.
Canonically located in Universe 666. In this timeline, she did not live in the human world until she discovered VShojo with Bubi's help. VShojo took over the world and divided among its members to rule as queens. Ironmouse brainwashed a family on Earth to believe that she was their daughter, then took a position as one of VShojo's queens to take part in the rule the human world, bring chaos, and consume souls. She also loves the eldritch being Nyanners and wants to take over the world with her. Her special powers include being able to travel to other universes. In this form, she has no silver bells to seal her power.
The model used for the VILLS concert. Former VShojo members Silvervale and Nyatasha Nyanners had matching designs. Designed by epebe. She has used this design in VRChat.
A model canonically depicting Ironmouse's form when she was an angel, prior to being cast out of heaven, as depicted in the HeavenFall animated cinematic. It has the ability to turn off the halo and wings, and to wiggle her hair buns which take the place normally used for her horns. It possesses a dark mode with glowing tattoos.
A joke Live2D model drawn by Nyatasha Nyanners, who also produced the Live2D model for Projekt Melody's VShojo debut. Based on the design of the Season 2 model.
