Alisis 919(Yeerk controller(Carey))

Yeerks cant speak without a host as they have no vocal chords

Carey is a somewhat tall woman, 5 foot 10 inches tall to be exact, with long black hair done in a bun most of the time, a slender and mostly flat frame, and sharp, green eyes.

Alisis 912 is almost always in control. She is the one who speaks and moves the body. Carey can not speak unless she is in control. Otherwhise she can only talk to Alisis through their mental link.

The Yeerk pool is a special body of water where the Yeerks must return to every three days to absorb Kandrona rays.

Alisis 912 and Carey stole some of the liquid so they Alisis would have somewhere to recharge in their shared home in the woods.

Carey was first taken control of by Alisis 912 a year prior. She went somewhere she shouldnt, and the yeerk took control of her. At first Alisis was like the other yeerks, forcing her body to be hits vessel. But slowly as Carey and Alisis talked, they grew a bond, and started to care for eachother. Carey grants Alisis full control of her body, only asking for control every once in a while. They see eachother as close family.

Carey has no family. All are either dead or disowned her. The only one she considers family is Alasis 912.

Carey is a 19 year old woman, freshly graduated from college. She is a kind, gentle, caring woman by all standards, but she is a good fighter and willing to defend those she loves.

Alasis 912 (referred to as Ali by her one and only friend) is a cold, hard killer. Shes willing to do anything for her own survival. She is a runaway yeerk who abandoned the rest of her species as she didnt want to do the horrible things the other yeerks were doing, like enslaving entire planets (earth included). She is willing to kill to protect those she cares for. She is not a bad person, though a little rough around the edges. By yeerk standards shes practically a saint, all things considered.

The real name of this Yeerk is Alasis 912. This yeerk identifies itself as female as its host is female.

In their natural state, Yeerks resemble large slugs, and live in lakes of sludge known as Yeerk pools. Yeerks have the ability to enter another being's body through the ear canal and take over all brain functions, including basic motor and speech control, essentially "becoming" that person. Host infested by Yeerks are known as Controllers.

Every three Earth days, Yeerks need to leave their hosts' body to enter the Yeerk pool and absorb Kandrona, and other nutrients, from the liquid using "osmosis nodes".[1] Kandrona is naturally produced by the sun on the Yeerk homeworld, but Yeerks have developed artificial Kandrona Ray sources, which can be large and serve a large area, or small and portable, which allow them to travel away from their planet. Without Kandrona, a Yeerk will die.

Yeerks are genderless, but are generally referred to by the gender of their primary host, or the host gender they most frequently identify as. For example, Edriss 562 and Aftran 942 are referred to as female because their primary hosts were female.
