someone: why do you like mettaton so much
me (internally): i think mettaton is a far deeper character than some people give him credit for- he’s deeply flawed and tends to be incredibly selfish, but at the same time cares a lot about certain people, more than i think he even realizes. he’s super complex and interesting and his relationships with the other characters - especially alphys and napstablook - are really interesting to me.
me (externally): sexy calculator
Mettaton is flashy but cares deeply about all his fans and makes sure to include as many of them as he can.
When cursing on your essay, he informs you that the show is family friendly, when he loses arms, he just roles with it which is great for inspiring his armless viewers like monster kid. He is willing to sacrifice his dream so of becoming a star in the overworld to continue inspiring the audience he has in the underground. Mettaton is a fantastic character.
