Mettabox

The Foiltale version of both Mettaton and Hapstablook, combined into one being: Mettabox.

About
In Undertale, his Mettaton Box Form is complete, but in Foiltale, it seems more like he's trying to force himself into it, trying desperately to ditch his past and be something entirely new.

Foil's Representation
Desire to run away from, keep hidden of, and leave his past behind him. Inability to accept his past as a part of himself.

Personality
Very much has the attitude of someone "putting on a brave face" and acting like there's nothing wrong when something clearly isn't right. He tries to laugh off his problems off and dismiss them, but he's clearly self-conscious about his current predicament. Usually out-right denies there's any problem. If someone is overly persistent about it, he'll start to get passive-aggressive and snippy. He tries to be haughty, but the act falls through when he constantly trying to make sure his Box Form doesn't slip away from him. Highly emotional.

Appearance
His Box Form, but with a ghost emerging from the top of it; formally known as “Hapstablook.” He generally looks like his Underswap version except always looking anxious and haughty. The metal box's arms are usually limp, the whole thing unpowered but still "standing up-right", and the pink ghost part that emerges almost seems to be clinging to the box, as if desperately trying to force its way back inside, but is being rejected. Still uses the box’s wheel when moving around. The gloves are pink and around the box's frame is a pink glow, symbolizing the ghost's connection with the metal body.

Sometimes the screen with blip to life when Mettabox talks, and die back down when he finishes speaking.

Abilities
Mettabox cannot be harmed by physical means as he’s an incorporeal ghost… Well, you could whittle away at his nigh-indestructible metal box body and eventually destroy it… If you wanted to be an uncaring jerk, that is. Plus, he's barely holding onto the Box Form at all times, so he can't really use it for attacks either.

Trivia

 * In the sprite art, the ghost part of him looks more like it's "melting onto" than "clinging," but this is the only way the author knew how to represent it.
