Slamurai

Slamurai, aka “Heroic White Ninja” is a figure that was planned to be released in 1988 along with 5 more figures, but plans never came to fruition. He appears to be a repaint Of Ninjor, reusing He-Man's legs and arms. His action feature is that if you pulled his arm back he would slam his arm down. Hence the name “Slamurai”. Cardback and action feature art were created for him.

Masters of the Universe Classics

Slamurai is a heroic warrior, and an enemy of Ninjor. On box art for the 2017 Power-Con exclusive set, he is seen fighting Terroar and Lord Gr'asp, implying he is also an enemy of the Snake Men.

According to his action figure's Bio, Slamurai was an honorable warrior who protected his home world of Bashido from Ninjor and an army of Terror-Cottas, defeating them with his Katana of Kuron which enabled him to magically outnumber his foes. He intended to live in peace until the magician Uncle Montork arrived seeking allies to help defend Trolla. Slamurai took up his Helm of Hikari, enchanted by the honor of his ancestors and able to protect him from evil spells. He then joined Uncle Montork’s reinforcements to turn the tide against the Revenge Squad after the death of Skeletor. Slamurai’s helm enabled him to free his friend Ra-Jar from the mind-controlling spells placed upon him by Lady Slither. Never one to boast, Slamurai returned home without celebration only to discover Ninjor had taken his own revenge by turning his wife Ageisha to stone with magic stolen from the Snake Men. Grief-stricken, Slamurai buried his enchanted helm at her feet, hoping its magic might restore her to life eventually. He then donned an assassins garb and searched for Ninjor as a spy and assassin-for-hire, thwarting villains across the universe by infiltrating their organizations while also gathering information on Ninjor's whereabouts. His quest ended on Eternia’, where he thwarted Ninjor's attempted assassination of He-Man on the day of his coronation, even though saving the Eternian cost him his chance to obtain vengeance. With skillful stealth and masterful fighting styles, Slamurai counters evils every strike!
