>>107321557I'm mostly just gonna focus on Eclipsa, both because Globgor hasn't received the extensive screentime or hype that she has for the last 3.5 years, and because I can see how making him evil would go against what the show's trying to say about monsters getting an undeserved bad rap (after monster villains like Toffee, Ludo, and Meteora even if they were going for "b-but it was the treatment she received that made her that way," it makes sense for Mina + possibly Solaria to be used as Mewman villains and somewhat balance them out). So in that case, and I've posted some of this before:
1. Globgor's actually good; Eclipsa's the evil one and has deceived him, or at least is selfish enough or has enough of a bizarre moral code to be using him for a bad purpose that he wouldn't go along with had he known. Ex. she says "all knowledge is good knowledge," pushes the limits of magic, etc. Maybe she hooked up with a monster and gave birth to a half-breed just to see what'd happen, and didn't really give a fuck about either of them. Maybe she really wants to like enslave Mewni or some dumb shit, and wanted to get even the monsters on her side. There's a lot that could be done
2. Get rid of the dark magic, like entirely. Eclipsa is villainized entirely because she left her kingdom for a monster. That way when she does turn out to be good, it feels like less of a letdown because we got exactly what we were promised. The dark magic can go to Solaria, and make her possibly being important at the very end of the last season have more of a leadup.
3. Globgor just killed Shastacan in his rage, not ate him. Someone can easily be killed in a fight/situation that escalates out of control, but eating feels both too purposeful and too sadistic to then accept him as a good guy (especially when he still jokes about his vore fetish). Maybe have it turn out him being eaten was propaganda and he just got killed, if the crew's just THAT vore-happy that they still want to mention it.
