"Diamond Jack!"

Ryuu Higashi (東 竜, Higashi Ryū) is Dia Jack of J.A.K.Q. He is a former Welter Weight Boxing Champion of Japan.

Age: 25-years-old

Actor: Heizan Itou (aka Shichirou Gou)

J.A.K.Q.
He was falsely accused of murder by greedy boxing promoters in Las Vegas when he refused to rig a Championship fight. He was intercepted by Joker when he was being extradited to Japan for prosecution.

Joker offered him the choice of working for ISSIS as part of JAKQ or serving his prison sentence. Higashi reluctantly accepted Joker’s offer albeit with reservations. His bionic enhancements allowed him to manipulate electric currents.

From his right second finger he is able to pull out his “Elek Cutter” [Electric Cutter] which he can use to cut through dense objects.

From his left ring finger he is able to pull out his “Dia Laser” which can fire a laser beam that can shear through most materials.

As Diamond Jack, Higashi wields the powerful “Dia Sword” which he can imbue with his electrical powers to strike with deadly effect. The sword can slash and cut through solid steel and other dense metals. It can also be used to focus and fire electrical bolts of energy.

Higashi is a rough and gruff individual who is at times very head strong. A bit of a loner, he does tend to prefer working alone. Continues to keep in touch with his former boxing partners. Higashi loves jazz music and fast cars.

Years later, Higashi fought alongside not only his own team,but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders.
