Original Description:
 
An AU of Unidentified in the form of an sci-fi alien-like arthropod. He has three different sets of eyes that does the following:
 
Top eye: Displays his current emotion via color, can blink and close, “eye lids” can be controlled to display emotions, but in a rather strange way.  
Function: Used to display emotions, and keep a look out at the sky. Also used to control magic, depending on what kind of story/role-play/plot he’s used in.  
Emotions:  
Blue - happy  
Red - angry  
White - sad  
Black - dead/emotionless
 
You can combine different colors to show different emotions like purple to display neutrality.
 
Middle eyes: doesn’t have eye lids, meaning it can’t close or blink. When sleeping, the iris fade away until they completely disappears. They obviously reappear when he wakes up. Generally, more sleepy/unconscious he is, the more faded his irises are.  
Function: Used like normal eyes/general use.
 
Bottom eyes: Can blink, eye lids can be controlled to display emotions similar to a normal changeling/pony.  
Function: Used to keep a look out at the ground for anything dangerous below.
 
17th Seeker is one of the last of his species after a group of hunters hunted tried hunting them down for sport. he currently resides alone in an unknown dimension trying to survive. He has durable shield-like legs that can block low caliber ammunition, sometimes medium caliber. The tip of his legs are also rather sharp. He has a stinger that can inject harmful poison, but the stinger is still rather small.
 
If you’re wondering, no, he can’t shapeshift despite looking like a changeling(for now at least).
