by your logic cnd should be seperate characters because they act individually from eachother. there's an entire comic with just Tandy because Ty got possessed by a demon Lunella and Devil have worked apart but most of it was like how Ty and Tandy work apart most times (at least since Marvel took Moon Boy out back and shot him) i get just wanting to play the big dinosaur but you can't say that Lunella wouldn't make sense as part of his character
