Demon Pandas (Patreon)

Normally this is the result of a (lost) bet with Normla, because he's really into this look, so I was about to say real demon wings and a tail are kinda non-canon. However after thinking for a minute, this is absolutely something  future Bastion is capable of with magic shenanigans. That means it gets the 'Totally Canon™ Seal Of Approval.'
