Manako

Manako (マナコ, Manako) is a monster of the Monster Association who was first seen using the toilets. She was then taken hostage by Flashy Flash and Saitama to lead their minecart.

Appearance
Manako is short and round, with light skin and one large eye. She also has two small horns, sharp teeth and wears a thick black belt that usually covers her mouth.

Monster Association Arc
Manako is using the restroom when Saitama and Flashy Flash came and took her hostage, using the monster to lead them to the Monster King's lair. As Manako was leading them through the tunnels, her plan was to de-rail them at a switching point to kill the heroes and herself, but chickens out when she gets closer to the broken rail and sees the vast fall.

Soon after, the trio passed through an excavation site in the Monster Association HQ. Other large mining monsters attacked them but were quickly killed by Saitama and Flashy Flash. Manako almost fell to her death but was saved by Saitama, who sacrifices the gold he was stealing from the Monster Association by doing so. A frustrated Saitama then pulls at Manako's cheeks to wake her back up after he fell unconscious from fear of falling to her death.

Later, she, Saitama, and Flashy Flash encounter the merged form of Psykos and Orochi, much to Manako's terror. When the merged monster tries to absorb Saitama, it slips off his shiny bald head. It is then punched, causing Psykos's portion to momentarily disappear while Flashy Flash and Manako watch on with blank stares. When Tatsumaki pulls the Monster Association Headquarters out of the ground, Manako, Flashy Flash, and Saitama are nearly buried but Saitama saves them. In spite of this, the trio is left in complete darkness afterward.

Abilities and Powers
Flashlight: Manako can create a large bright light through her one eye, allowing her to be able to move when surrounded in complete darkness. It is strong enough to blind the eyes of S-Class heroes.
