oh my god i'm in the battle tower of Pokemon and I'm listening to the battle theme and going "hmmm this kinda sounds like something outta undertale, haha. it's a great track though, actually the best in the entire game. Wow wouldn't it be funny if toby fox had actually made this track for pokemon haha-*memory recall finally*-aaAAAAAA OH FUCK HE DID DIDN'T HE?!"
Actually to be fair both Marnie and one of the gym leaders have amazing goddamn themetunes for their battles holy shit. Like you know shit is real when a gymleader has their OWN battle theme. that's how rad that character is. fuck yes.
(hopefully that's spoiler free enough)
