mint-bees:

Im about to pass out from exhaustion but i just had a really bad realization so hear me out on these facts

– alphys based her understanding of humans off of anime Which is why mettaton looks like that tm

– in order for mettaton to speak he needs a voice using like a program with vocal sounds in it

– monsters get most of their technology from humans

– there is only one voice generator program that comes to mind that could realistically have been in the piles of trash alphys gets her anime from

Conclusion: it is extremely likely that mettaton sounds like a pitched down hatsune miku SIRI SEND POST
