Oil Man, unlike his polar opposite Time Man, Oil Man has a carefree and reckless attitude similar to that of stereotypical punk teenager, has an urban style of speaking, and does not always take battling seriously. He enjoys oil and believes it's the answer to everything, often giving his comrades fill-ups, and likes skateboarding, sometimes using said oil to make a skateboard. This also serves as his special weapon, the Oil Slider.

He was made by Dr Light.
