Species: Guardiano

Continuity: Transformers Prime: Rise of the Guardianos and some mentions in Transformers Prime: Legend of the Guardianos

Onyx is very mysterious.

She doesn't transform so her design may be confusing to the transformers artists out there, but I promise you, it's mostly for ascetics and battle armour.

A few of the early designs insisted that she was supposedly the guardian of the Sharkticons but I'm reconsidering it since she died before Rainstorm while Sharkticons are still around all the way through the RID continuity.

Availability: your options on how you use her are quite limited if you want to use her in the correct timeline but go right ahead.

Preferred fighting style: unknown, only seen using ranged magic from her genetic abilities
