キン肉マンII世
The Ninja is a ninja Choujin, employing various ninjutsu techniques such as the "Scorching Hell", where he uses fireballs as mini-suns to scorch an incapacitated opponent. He fought Brocken Jr. during the Five-Story Ring within Warsman's body. Although he had the advantage throughout the fight, Brocken won in the end, with The Ninja impaled on Junkman's spikes. The Ninja turned up alive and became a member of Team Soldier during the Scramble for the Throne arc. He fought Satan Cross and was killed by his Triangle Dreamer, but was brought back to life along with the rest of Team Soldier by Kinnikuman's Face Flash. In the Perfect Origin arc, The Ninja fights and defeats Crowman, and later presents Crowman's Dark Dumbbell to Akuma Shogun. In the "Ultimate Muscle" dub, The Ninja is renamed Ninja Ned. The Ninja's voice actor is Masashi Hirose.
