I'm at Comic Con this weekend and there has been no Carmen art, merch, or cosplayers. I suppose it's on-brand to be hard to find, but I had hoped to pick up some swag with the recent upsurge in popularity.))
No merch means either nobody picked it up at the licensing convention or it’s not yet open to third party licensing. On the up side, the cartoon series has won an emmy (juries) for background animation.
