Wait would it be possible to like send a petition to the people who made super smash bros and ask if they can add mettaton,or do we just have to wait and see if they add him?
SO I THINK WE ALL KNOW SANS IS IN SUPER SMASH BROS,BUT AM I THE ONLY ONE WHO WANTS METTATON IN THERE TOO? IMAGINE A VERY FLAMBOYANT ROBOT WHO FIGHTS WITH A CHAINSAW OR BY BASICALLY DANCING,AND THE FACES THAT OTHER PEOPLE WILL MAKE THINKING "WHO IS THIS,WHY ARE THEY HERE?WHY DO THEY GIVE OFF GAY ENERGY??"; AND EVERYONE IN THE UNDERTALE FANDOM WILL WATCH AS THE OTHERS PANIC TRYING TO FIGURE OUT WHO TF METTATON IS
