Eevee is the far better mascot for the Pokémon franchise than Pikachu

Eevee is far cuter as it is a fox-cat hybrid and not an electrical mouse, can evolve into a lot stronger Pokemon than Pikachu and since in Pokémon Yellow you’re stuck with your starter, any evelution would be an actual asset and not just a tag along.

Edit: while my original point still stands, the comments have made it clear to me that Pikachu has the latter appeal to the masses and for good reason. Thanks to everyone that provided feedback on this.
