Try and tell me you WOULDN'T pay for this to be an actual, legitimate fighting game. As Samuel l. jackson said: I dare ya! I double dare ya, mother fucker! Because this animation is amazing, epic, and smoothly beautiful. And we have a pretty impressive number for a roster. So in short, all we would need is for someone to get smart, and make a SSBU/atari-godzilla style fighting game for us kaiju fans.
Hell, if we wanted to reenact the "World of Light" trailer, we could have AnimeGhidorah combined with MonsterverseGhidorah to play as Galeem, the Seraphim. Imagine all of those death beams shaped like hundreds of those vicious heads vaporizing all of out heroes, AND villains with ease.
Now, let's see if we can figure out who'd be out resident Kirby, and save the day.
