Design
The Diet Tank is a large, nearly spherical, bomb-shaped Unversed. Its upper body is bright magenta and its lower body is a dull, faded shade of purple with pale gold stripes. Its head is spherical with a tall antenna resembling a wick on the top of its head. Its head and the area around it are dull purple, and the area around its head has a pale gold outline shaped like an eight-pointed star. Its arms are very short, nearly spherical, and seemingly useless. Their tips are dull purple and sport short rods. There is a golden valve on its upper back. The Unversed's red eyes are set in an angry expression and a large Unversed emblem adorns its chest. It has been shown to inflate and deflate at will.
