Inside

he/him

izqui (ee'z key) is the yellow, ereda (air ey da) is the blue

izqui wanted to become a "perfect" being (not necessarily perfect, but rather without deformity)
- this is made more obvious  by his design before fusion
izqui was a scientist and very smart so cool so cool

fusion with ereda to replace the "corrupted" eye

izqui is more dominant in control, ereda can move his legs but they are too small to really do anything. ereda's eye will usually follow izqui's but doesnt always have to, and his expression is generally similar to izqui's, but has a lot more freedom.
izqui believes ereda to be a much larger mistake and wishes to rid himself of him as he is another "incorrect" part. regrets fusion entirely

Inside is generally serious, and wishes he only had one eye.

He is more like two separate people than a fusion of one mind

Despite having a mouth, he does not eat

Incapable of sleep
