Thinking about Metta having multiple robot bodies that he swaps between, popping his head off and on depending on different gigs/shows he's doing.
Of course, one of them being massively obese...
"Oh, this ol' thing?"
Mettaton said with a bashful smile, placing a gloved hand against the wall of fat that loomed behind him.
"This is actually one of my earliest bodies, built about... I want to say nearly a decade ago at this point. Some old experimental bio-reactor that was meant to simulate eating, as well as digestion and calorie storage. As you can see, smashing success darling~"
The headless form's neck socket was just barely visible over its mountainous bulk. It was clearly immobilized by its own weight, its legs thick as car tires and spread wide in order to accommodate the enormous gut that took up most of its body. The belly itself was easily taller than Metta, and was several times deeper than he was tall, from the cavernous navel that sat on the front to the rolls that connected it to his hips. The whole thing had the dimensions to easily contain a car.
Somehow even more impressive was its ass. Each cheek was nearly the size of his stomach, sitting side by side as they took up a majority of the room. The upper body, what was visible of it at least, was reclined against it just as if it were resting against a plush couch.
Sitting atop the mountain of belly attatched to the chest were two hefty breasts, each at least the size of a bean-bag chair. The last shredded remains of what used to be its latex bodysuit, which every one of Mettaton's robotic bodies wore, was stretched across them. It provided some amount of modesty, though it couldnt hide the dinner-plate sized areola's from peeking through, a shade darker than the rest of the body's pale synthetic flesh.
"Darling, my eyes are down here~"
He teased, snapping your gaze down to him. He laughed as he saw your visible embarrassment.
"Oh dont worry darling, I know it can be a tad... overwhelming to some folks that see it. Play your cards right and I might let you have some fun with it tonight~"
He said with a wink.
