Actually you nearly correct, his eyes are gone and those replace his eyes, here’s the story.back story and desc:
Tristan was walking around planet star globe
when he came across a patch
of glowing moss, out of curiosity,
he decides to step on it,
it ripped his eyes out and made an extra socket.
it stretched him out and his left elbow became
rocky…his insides were twisted
and mushed. he grew claws during the
transformation.
