EnbyKerbs adds eight new textures based upon the default kerbal textures. Since they mix up the gendered characteristics of the existing Kerbals, you can think of them as "transgender" or "nonbinary (n.b. or enby)." Those gendered characteristics are: the head shape, the hairline, and the eyelashes.

For reference, the default heads are:

• rounded head shape with a flat hairline and eyelashes
• square head shape with a widow's peak and no eyelashes

The new heads are:

• rounded head shape with a flat hairline and no eyelashes.
• rounded head shape with eyelashes and a widow's peak.
• rounded head shape with a widow's peak and no eyelashes.
• square head shape with a flat hairline and no eyelashes.
• square head shape with a flat hairline and eyelashes.
• square head shape with a widow's peak and eyelashes.

And as a bonus:

• rounded head shape with no eyelashes, a widow's peak, and a moustache.
• square head shape with no eyelashes, a widow's peak, and a moustache.
