Undertale Voice Headcanons

this is just how i imagined some of the characters sounding while i played undertale for the 20th time over all art belongs to me (aside from the talk sprites and voices of course, minus the terrible Gaster sprite that i made myself since he doesn’t have one) Voices: Asriel — 0:00 Ash Ketchum (Veronica Taylor) from Pokémon The Series: Indigo League Flowey — 0:21 Bill Cypher (Alex Hirsch) from Gravity Falls Asgore — 0:53 Michael (Ted Danson) from The Good Place Papyrus — 1:15 Jackcepticeye (Seán McLoughlin) from jacksepticeye Sans — 1:43 Adam (Adam Ortiz Jr.) from SomeThingElseYT Napstablook — 2:00 BMO (Niki Yang) from Adventure Time Dr. Gaster — 2:25 Otto (Kester Lovelace) from The Sounds Of Nightmares Mystery Man — 3:09 The Ferryman (I actually couldn’t find who voiced him—comment if you know haha) from The Sounds Of Nightmares comment your own voice headcanons for them if you have any! or if you have voice ideas for the other characters oh and i’m not 100% sure exactly what mystery man/the ferryman is saying so take the cc with a grain of salt
