Shinobi

Shinobi is a powerful ninja warrior, highly adept in the skills of sleuth and blending into the darkness. Originally a drone minion constructed by Aku's scientists to eliminate the troublesome Samurai Jack, Shinobi unfortunately failed his mission and was terminated in the attempt. However, Aku saw too good an opportunity wasted, and decided to mystically transfuse his DNA into the sparking body of the robot, creating a new son.

Shinobi quickly grew a personality outside his narrow mindset of killing the Samurai, actually learning about the Ninja and their place in Japanese culture, alongside attaining numerous other interests aside from combat. These include creating bonzai trees and katana-crafting. Shinobi spoke rarely, if ever, not using his newfound voice often other than too communicate frequently with Aku about military intelligence and other important matters. He became the demon's most beloved child. Jealousy harbored in Demongo, the older son of Aku, whom challenged his counterpart to a duel.

Meeting his stark rival atop an unnamed volcano, Shinobi used his mastery of night and dark to sneak by Demongo's enslaved warrior essences. Despite this, Demongo had a litany of other attacks at his disposal, mainly dark fireballs. Shinobi attempted to sneak attack the cunning wizard, but Demongo teleported to his adjacent side and burned the ninja with fireballs. His shrieks of pain were so loud and shrill his voicebox imploded, thus returning him to an eternal state of silence.

Aku broke up the duel before Demongo could kill his son, deciding to promote Demongo to Supreme Commander of his armies and resign Shinobi as a mere intelligence officer for his failure. Shinobi's shame overshadowed his life, he wailed at night but unable to cry, depressed beyond all measure.

He vowed vengeance on both Demongo and Samurai Jack for their numerous crimes against himself, becoming dark-hearted. Dedicating his life to battle and abandoning Japanese warrior codes, Shinobi was dispatched by Aku into New York's criminal underbelly to retrieve a relic capable of powering a time portal, which the lone Samurai sought after as well.

Shinobi infiltrated the mafioso boss's warehouse, discovering a massive treasure trove of technological gems horded after numerous alien incursions on Earth during the Universal Wars. Old HYDRA Wardroids were used as goons to protect the weapons cache, but their outdated systems and incompatible targeting computers were no match for the stealthy and silent Shinobi.

After eliminating the guards, Shinobi discovered the desired relics and prepared to return home, only to find the angered mafia boss and an armed retinue of his bodyguards standing outside with tommy guns. Before another fight could break out, one that Shinobi had little hope of succeeding in, a stranger arrived and sliced the guards into swiss cheese, knocking the boss unconscious. It was Samurai Jack.
