Wait so does that make Hanekoma Toriel? Kitaniji Asgore? EIJI OJI METTATON????
You got it! ;D
Toriel Hanekoma meets Neku in the Ruins and helps him understand monsters aren't so bad and maybe if he trusted them a bit, he could get through a seemingly impassable challanges. Instead of a Queen, he's more like a "right hand man" to the king, but disputes with the current ruler made him break away from politics. Also, he makes some mean boulliabasse and coffee (which, yes, he almost gave caffeine to a kid).
Asgore Kitaniji is the current king of the Underground. He wants to free monsters by taking the souls of humans that fell. He fears the prophecy of an angel of death coming to destroy them all but is also blind to what his people truly need. He is one of the few able to hear the sound of souls. His headphones symbolize his golden crown.
The Deltapin is the emblem of the royal family. It sits on the backs of Mr.H's, Joshua's and Kitaniji's clothes.
Now, I knew I wanted Mettaton to be a combination of Mr.Mew, since Shiki-Alphys was the one that made him. But you gave me the image of Eiji Oji being Mattaton EX and it's faBULOUSLY BRILLIANT
MettaMew is the resident celeb and social media influencer who runs the most famous blog in the Underground (it gets 13+ hits daily!). How does this thing move on it's own again...? Anyway, it somehow got programmed to catch humans as well, which they do no not love but hey, that's showbiz!
MettaMew EF is the fabulous upgrade that Shiki has been working on to suit MettaMew's more... flamboyant tastes. It's pretty embarrassing, to be honest;;;
Mettamew's personality is that of Eiji, and when they speak, it's robotic and monotone, even if the context it joyous. MettaMew EF is more natural and flamboyant, sounding less digital. (If you've seen Jacksepticeye's version/voices for Mettaton, it's close to that.)
