Scritchy resembles Moskevil, except the fact that she is a female. She is light purple with wings of the same color, a dark tan beak, purple eyes, and lilac purple antennae. Instead of a purple hooded robe with darker stripes, Scritchy's is yellow with light mint green stripes.
In the anime, the Scritchy featured -her name is Sarah- dedicates herself to give bug bites to people; however, she does not enjoy the fact that her schedule is packed and she cannot sleep. For that reason, she wants to have an easy bite.
She sucks blood from her victims and leaves covered in bug bites.
Her son (in the future) is John. He impulsed a treaty of peace with the humans in the future after a war broke out and agreed to travel to Mars. However, John requested Robonyan F to go to the present to protect Sarah.
