Appears in episode 22, his origins are explored in episode 30, and his true level of power exposed in episode 50. He has also effeminate manners and the new design has Him in more of a harlequin-esque motif/Joker-like. He now has a yellow skin color, but he retains the habit of changing the tone of his voice from soft and effeminate to loud and enraged. Like the original, no one can mention his real name, because of how frightening his name is (Professor Utonium actually tells Ken the name, but the viewer is unable to hear it. Just mentioning the name frightened Ken and Peach). In this version, Him is a demon who brought about chaos and destruction in Edo (the city that eventually became Tokyo City) long ago. However, he was eventually defeated by the Ōedo Chakichaki Musume, three super heroines who resemble the Powerpuff Girls Z. Him's powers were drained and his body was sealed in a coffin. The coffin was buried at Ueno Shrine, which later became an abandoned museum when the shrine was caught on fire long ago. It was there that Him remained dormant, until the most potent Chemical Z black light brought him back to life, although the seal prevented Him from escaping. In order for Him to escape, Him created a mummy whose sole purpose was to undo the seal by obtaining the white energy of the Chemical Z white lights. The mummy, although defeated by the Powerpuff Girls Z, was able to drain their energy, and its bandages returned to the abandoned museum and broke the seal on the coffin, allowing Him to bring about chaos and destruction once more. Him's main power is the ability to unleash an evil black particles. These particles is able to sway people/objects to the side of evil and transform its victim into a monster (The black particles eventually takes the place of the black lights). In addition, Him has total control over his particles. He is able to call them back at will, change the speed at which they move, communicate to his victims, and can view the memories of whoever or whatever was affected by his particles. In actual combat, Him is capable of stretching his limbs to lash out at his enemies.
