H-Howdy! I..... am Jazz, a car... I guess?
— Jazz introducing herself.
Jazz is a car-like monster that encounters in Hotland. Along with Mettaton and Tsunderplane, they are all mechanical monsters and SHOULD Have a ghost form.


Normally, she appears to be a normal small, purple hatchback. She has a black line on eyelids and is green and a blush.


She is a bit shy and active, also friendly but with her tires being harmful, it was Alphys' fault by giving her the really hot. She likes singing like Shyren and Music, Sport, Dropping by in MTT Resort and Whistling.
