MYSTERY SOLVED:
It was a mix between Umbreon and Flareon, like a "what if" scenario for an Eevee evolution that was Dark/Fire type, which she'd seen around 2020…
Thanks everyone, but there was no way we were going to solve the mystery. And I'm also so sorry for the wasted time.
My friend says her favorite Pokémon was like Ninetales but with red and black, but I showed her Zoroark and she told me it wasn't bipedal, it was quadrupedal. I don't know if I'm the stupid one who doesn't know what it is or if she's confused.
Thanks a lot.
Edit 1: She says that it's almost all black (?), fire or orange hair in the foot, a fluffy tail and was kinda elegant (?). At this point Idk if she's just jocking around but she's very serious about it. I will update with what Pokémons aren't.
Edit 2: She drawed it, it looks like a normal fox (?) With a fluffy red chest and the tip of the tail is red.
