Alisa is an undead being / toy doll who feasts on UMA aliens to gain humanity. Her adoptive father, Nevula, is the black alien who is trying to give Alisa a human form. She befriends the Keroro Platoon after Fuyuki Hinata protects her despite what she had done to them in episode 133. In the manga, she only captures aliens and imprisons them in a box, referring to them as the "Dark Race", but is stopped after her father is attacked by Angol Mois.
Alisa has scarlet eyes, long yellow-orange hair put in pigtails in the back held in place by two sky blue glass-like orbs. She usually wears a long sleeved black shirt, complete with white cuffs and a light gray blouse over the shirt with a small black ribbon, a small dark gray skirt, black tights, pointy white socks and black mary janes. Alisa's father usually rests on Alisa's head in the form of black cat ears. '
In the Flash Series Alisa has dark gray orbs holding her hair up and she wears a long puffy sleeved shirt with black cuffs, black suspenders attached to a corset around her waist and a little black messy ribbon attached to the collar. She wears a black and white ruffled skirt, black tights, small spiky white socks and black mary janes. Alisa sometimes wears her father on her head, but when he transforms into something else she wears the same black cat ears. [Source: wikia]
