Maiko Plasma's Upper Body Appearance

Maiko Plasma's appearance was that of a Maiko; with her black hair tied up in a traditional Japanese way with many decorative hair clips with stars, clouds and thunderbolts. As a Maiko, she wore a long kimono called a hikizuri, with clouds and thunderbolts printed on it, a black obi sash with two belts tied over it and wedge-heeled wooden sandals. Around her, she had eight Tomoe drums attached to her back and carried two drum sticks in her hand.


Maiko Plasma seemed rather calm and acknowledged that there are more powerful beings than her in the world, a trait very few low threat level monsters have.[2]


Human Monster SagaEdit

Monster Raid ArcEdit

Maiko Plasma and Electric Catfish Man go to attack the recently rebuilt D-City. At the city, they encounter Lightning Genji. Unfortunately for Lightning Genji, their attributes nullify his stun attacks.[3] The monster pair eventually defeat Lightning Genji.[4]

Monster Association ArcEdit

In the Monster Association, she and Electric Catfish Man are discussing their victory over Lightning Genji and remarking that it was thanks to Gyoro Gyoro and her carefully-planned choice of who they would fight that the pair won against the A-class hero.[5]

Later, Maiko Plasma, alongside other Tiger level monsters including Electric Catfish Man, are attacking Puri-Puri Prisoner. When their attacks have no effect, they attempt to flee only to run into Vacuuma. Vacuuma tells them not to retreat, to which the monsters angrily ask him to fight the S-class hero in their place. Vacuuma agrees and subsequently consumes them all to gain their powers, signifying the death of Maiko Plasma.

Abilities & PowersEdit

As a Tiger level threat, Maiko Plasma was a threat to the lives of a great number of people. Despite her disaster level, she was able to defeat Lightning Genji with the help of Electric Catfish Man, albeit with both of them having a type advantage over the hero.

Supernatural AbilitiesEdit

Electricity Manipulation: As an electricity-based mysterious being, Maiko Plasma had the ability to generate several bolts of electricity. Her electricity was rather potent and was generally pink in color.

Fighting StyleEdit

Miscellaneous AbilitiesEdit

Tomoe Drums: Maiko Plasma possesses eight Tomoe drums that shot a bolt of lightning when she hit them with her drum sticks.[6]
