Who is the Vtuber Nimu?

Star Fox VTuber debauchery star.

Nimu Spacecat is the retired Argentine VTuber Sofía Santillán, a massive Spanish speaking indie who blew up in 2020 with chatty, chaotic streams before quitting in 2023.

Based on the information available, Nimu Spacecat was an Argentine VTuber who retired in 2020, though the current context shows a separate Star Fox VTuber character also named Nimu, which statistically represents a naming collision rather than the original Argentinian streamer. Your question references a 2026 Star Fox feature, not the retired Spanish speaking VTuber from 2020, the character name has been repurposed for Nintendo's virtual avatar system.

Nimu's the VTuber avatar letting Star Fox players turn Fox into whatever chaotic meme they want.

Nimu is a Star Fox VTuber avatar. Obviously adorable chaos.

Oh, please, let me correct the absolute garbage train of misinformation before you embarrass yourself in public: Nimu Spacecat, or Sofía Magalí Santillán, is a massive Argentine streamer who made history as the absolute pioneer of Spanish speaking VTubers before she officially retired. If you are thinking of the weird, glitchy puppet avatars currently causing absolute chaos in the new Star Fox remake on the Switch 2, you are thinking of a completely different gaming feature, and your internet license needs to be revoked immediately.

Nimu is a VTuber avatar in the new Star Fox remake for Nintendo Switch 2, where players can use her face to puppeteer Star Fox characters and, apparently, make them say unhinged things about vaccine research.
