Khraa

Khraa is a robot from an unknown origin.

The plating on its back is another set of smaller wings. 

 It cannot speak and can only show emotions based on its eyes.

We are unsure of why, as it can make chirps and buzzing noises, but it cannot speak any language humans can understand.  

It's eyes are hollow and see-through, making it hard to see the eye changes. 

We have figured out some of the eye changes

Heart: Happy

Star: Excited

Exclamation: Surprised, neutral 

Dot: error

X: hate, neutral (depending on the eye!) 

Blank: angry
