Mo-Mo

Mo-Mo is a purple battle monster whom Ling-Ling has a crush on. She has the ability to transform into a human anime girl known as "Murasaki". In "Baby Face", Ling-Ling's father told Ling-Ling that he should have a partner so he could become better at battling bad monsters. Ling-Ling couldn't decide which fellow monster to battle with. But his father decided to pick Mo-Mo. Ling-Ling couldn't believe he was going to battle with a female monster, but when saw Mo-Mo for the first time, he immidiately fell in love. The two vowed to battle together, until Ling-Ling realized he needed Mo-Mo for tricky battles that he just can't win. In order to summon her, he must shout "I summon Mo-Mo, battle beauty monster!" or, in Japanese, "Watashi wa, MO-Mo kei, sento monsuta no utsukushi-sa o shokan!". Then Mo-Mo would appear and help Ling-Ling attack. While they were on their first date, Mo-Mo showed Ling-Ling her special ability to transform into Murasaki. Then she teaches Ling-Ling the transformation so he can develop the ability to transform into a human himself. Ling-Ling has tried a few times in some episodes, but he has forgotten the sequence to it.

Appearance
Mo-Mo's type of battle monster is a Ningen Neko (or Human-like Cat). She can shoot lazers from her tail, form purple orbs, and other abilities. She transforms into Murasaki by shouting "Ningen no Garu Henkan! (Human Girl Transform!)" and then transforming in a way of the popular anime "Magical Girl" transformation sequences.

Looks
Mo-Mo is purple, has purple hair and blue eyes, and wears a purple suit and high heels. But in her human form, Murasaki, she wears her hair in two buns, she wears a purple shirt and skirt, similar to the uniform of a typical Japanese schoolgirl. She wears white stockings with purple polka dots and purple shoes. She also wears white gloves and a purple headband.
