Speed King

"MERAARYARYAAAAA!"

- Speed King's battle cry

Speed King (スピード・キング) is the Stand of Jobin Higashikata featured in JoJolion.

Appearance
Speed King has a humanoid appearance. It possesses a mannequin-like body and a human-like face with holes for eyes (later depicted as goggles) and a flat raised surface resembling a nose, as well as a fisherman's cap with several metal spikes along the brim and various strings of equal length sticking out from both sides. It has two large horns on each side of its head, a wide mouth, bearing gritted teeth along with pores and bumps over its 'skin'.

It appears to have robotic joints across its arms, and a fur-covered, vest-like torso. Speed King's body becomes very skeletal and robotic below chest-level, lacking much of an abdomen and instead having metal bars and other apparatuses connecting it to its lower body. When Jobin first manifested Speed King, it was small and childlike, with softer facial features and a large head, due to Jobin being a child at the time.

Speed King is bright orange and red in the colored manga. This color scheme, along with its facial expression, could be noted as similar to Japanese 'haniwa' ritual statues.

Abilities
Little is known about Speed King's abilities, but it is clear that its heat powers are lethal at both close and long range. Speed King is shown to be able to punch enemies rapidly, as shown on the very last page of chapter 73, but the extent of its power is never revealed. The Stand has also been described as having "hidden abilities" that Jobin keeps undisclosed even to his own family, but it remains unclear what they are.

Heat Accumulation
As explained by Jobin, Speed King has the ability to store heat and temperature within a short, localized point, from single objects such as the surface of paper money to any particular spot on the human body. However, the heat can then be transferred to anyone who touches said point where the heat is stored. More specifically, Speed King takes advantage of the laws of thermodynamics (in this case, entropy) by accumulating heat within a medium and preventing that medium's temperature from lowering. By preventing the temperature from lowering, the laws of thermodynamics will cause the temperature of both objects to attempt to equalize themselves, causing the rapid transference and buildup of heat from the medium to the target.

Speed King can only affect objects within 10 centimeters, but it is shown that said objects can travel far away from Jobin and still be affected by Speed King's heat storage. For instance, Ojiro Sasame could travel from the Higashikata House to downtown Morioh and still be affected.

Since Jobin can heat sodium chlorate enough to produce oxygen, it can be inferred that it can raise the temperature to at least 300°C. He has used it to melt the wax stuffed into his beetles after brushing them with a paintbrush and has given Josuke a nosebleed simply after offering some tissues to wipe his face with. This power can be weaponized and used to heat people's blood vessels, boiling the blood inside to render them unconscious or even kill them. When applied to the temples the heat can become so damaging that the eyes will burst. It can also be used to cause a heat stroke and heat blood vessels to cause death.

Trivia

 * Like all other Stands used by members of the Higashikata Family, its name includes the word "King".
 * Yuya Fungami, a character from Diamond is Unbreakable, has the words "Speed King" emblazoned on his tie.
