>IT NO GOOD BECAUSE NO BIG BAD KING KOOPA GUD VS EBIL FINAL BOSS!
AT was complete shit stem to stern so I have no comment on that, but SvTFOE's "final boss" wasn't a physical being but rather the idea of segregation and systemic racism, Mina even explains so as much in her final appearance. It wasn't just Mina who fell prey to this but a sizable portion of Mewni's population, including Queen Moon. While some were willing to change their ways or had regrets, others were not. It's something that can never truly be defeated unless you drive all the rural and suburban retards back in the woods so they'll stop voting for Drumpf.
