Eeveelutions are a group of eight Pokemon that evolve from an Eevee. It’s a significant term as fans coined it and later adopted by the Pokemon Company for Pokemon Stadium 2 when it first appeared official. They’re adorable.
Chibi is a slang term used by anime fans for something small and cute. In fact, it comes from the verb ‘chibiru’ which means ‘to wear out and become shorter’.
Yeah, so fan created Chibi Eeveelutions are shorter, cuter, versions of Eeveelutions.
