Earrig

Earrig is the Simplicitrix/Stabilized Simplicitrix's DNA sample of an Yeerk from the planet Involventcaput Circa-Quod.
==Appearance==
Earrig is a relatively small alien resembling an oversized slug. His body is primarily green, with brown-orange patterns on his tail, fins, and antennae. He has a purple gradient along his back, and his entire body is covered by purple and orange bumps.
Earrig wears the Simplicitrix symbol on his face.
==Powers==
*When Earrig crawls into a host's ear canal (or some equivalent orifice that leads to the brain), he can wrap himself around the brain of the individual and takes full control of their body. As he has access to their memory when in this state, Earrig is able to seamlessly mimic how they act and what they remember, effectively becoming his host. He has full access to their powersets, as well. Anyone under the influence of Earrig is called a Controller.
==Weaknesses==
*Not every species is compatible with Earrig.
**Some species, such as Pyronites or Prypiatosian-B's, would destroy him just by getting close enough.
**It's possible that Culina Sequuntur Somnias and Bùyàoràngwǒmende Shíwùbèi Jùjuélenǐ are able to harm him as well due to being salt-based while Earrig is a slug.
**Earrig is capable of controlling some level of more mechanical species, but it is unclear what this limit is.
**Earrig cannot enter a Celestialsapien's brain due to the nature of their headspace; the only way he could manipulate a one is if he was controlling some form of Simplicitrix or Omnitrix wielding individual and then became Alien X.
*Earrig's species need to be able to absorb an energy called Kadrona, either by his homeworld's sun or artificially made Kadrona ray pools. This is not typically an issue, as the limit for how long a Yeerk can survive without Kadrona is three days, and the user will likely not be in this form for long enough for it to matter, and switching between forms would reset this, or at the very least give them a chance to find some other sustenance.
*In most situations, Earrig is incapable of transforming while inside a host to prevent killing the host unintentionally, a failsafe of the transformation. However, a forced detransformation (or any form of transformation out of Earrig) will override this. You cannot intentionally Ant-Man your Thanos host while as Earrig.
==Etymology==
*Earrig's name is a play on "earwig" and "rig."
*Earrig's planet name is a corrupted version of the Latin for "wrap your head around that," a reference to how Earrig wraps around the host's head.
==Trivia==
*Earrig was drawn by Shark using an official illustration of the Yeerks from Animorphs. Shark also named the alien, though had initially suggested the spelling of Earrigg.
