I'm not actually rewatching MLP, sorry for confusion? (Been rewatching SU, maybe that's what you're thinking of?) Anyhoo, sitting on this ask... I guess I have to accept I Do Not Have thoughts on Cozy Glow. This sort of design & demeanor can appeal to me, I don't dislike her, but I didn't feel compelled by anything the show did with her...! A filly playing the role of antagonist is an exciting concept but it is ruined by how much idgaf about Tirek... and ultimately she doesn't have any interesting motivation, just power hungry, and then we like. Imprison her in tartarus and that's fine ig... because she is, evil. The evil villain alliance stuff also VERY BORING completely asleep for it. As with most things in FiM i just find her underutilized, but I could appreciate her design and if anyone made thought-provoking fanart. And I would be happy to draw her... that sorta thing.
