What exactly here is mlp fan character? That's not a pony, not even an anthro pony. It's just a succubus with heart on her thigh, which isn't even the general location for a cutiemark if it's meant to be one.

Looks more like a Jabberwock from Monster Girl Encyclopedia.

the original tweet even says "Jabberwock girl"
