Erasem

Erasem (Memory Lapse in Japan) is a small yet deadly monster accidentally hired by King Dedede. However, unlike most monsters that Dedede orders, she attacks Escargoon instead of Kirby. As Escargoon wanders the streets of Cappy Town unnoticed and unrecognized the next morning, it soon becomes apparent that Erasem's power is to make her foes disappear from everyone's memory, leaving them alone and forgotten about. Luckily, Kiry is somehow able to see Escargoon, and able to convince his friends to help. The gang beat up Escargoon to expel the monster, which is the only way to free him. Escargoon is eventually freed from her clutches. But before Kirby has the chance to destroy Erasem, she disappears, never to be seen again.

Physical Appearance
Erasem is a tiny, pale, insect-like monster, and also appears very ghostly. She has a small horn sticking out of her round head and very small arms. She has thin eye holes, and is often seen traveling in a bubble when not inside the body of one of her victims. Erasem is also one of the few female monsters from Nightmare Enterprises.
