Silver Samurai Silver Samurai (Kenuichio Harada), the illegitimate son of
Shingen Yashida, is a Japanese
mutant with the power to charge almost anything, most notably his
katana, with mutant energy, which is described as a
tachyon field and allows it to slice through all substances except for
adamantium. He wears a suit of traditional
samurai armor made from a silver metal, hence the name "Silver Samurai". Once the bodyguard for the international terrorist
Viper, and later an occasional
mercenary, he later became the head of Clan Yashida after his half-sister
Mariko Yashida's death and attempted to pay off its debts to the
yakuza and restore its honor. Though formerly one of
Wolverine's enemies, he impressed Wolverine and he entrusted him with the care of his adopted daughter,
Amiko Kobayashi. He also helped Wolverine destroy the monster Doombringer and rescue Amiko and Yukio from their kidnappers. During his time as a hero, the Silver Samurai became the leader of the Big Hero 6. Silver Samurai later became the bodyguard of the Japanese prime minister, but was killed defending his family from a ninja attack.

X-Men and a former nationalist who changed his views after the death of his father and possesses the ability to fly and generate super-heated blasts of
plasma. He became one of Japan's most prominent heroes, but soon left Big Hero 6 to join the

However, before the project was completed, Hiro's father died, and he used his brain engrams to program Baymax's artificial intelligence. Now possessing his thoughts and emotions, Baymax became more than a bodyguard, as he also became a friend and father figure to Hiro. Baymax also feels a deep connection to Hiro's mother, Maemi; however, he and Hiro decided that it was best not to inform her of Baymax's true origins.
