Just something I came up with, May or may not be a thing in the future but they are my babies, lol.

Will scrap later.

Dro'Ca Biological Starships are living carbon based life forms, that live primarily in space, The metallic structure of their bodies is composed of a flexible nanite polymer which is incredibly resistant to radiation and heat.

Created to have regenerative properties should that normal spaceships won't be able to recover from either it be collisions or gunfire, Dro'ca can recover from practically any types of damage, aside from complete limb loss.

Males and Females are of completely different sizes due to their different roles.

Females range from Carrier classes to Planetary classes, their primary role is for transport and living space, allowing them to double as space stations in a pinch.

Males range for Fighter classes to Cruiser classes, their primary role is for Offense and Defense.

Young Droca are small, ranging from hand drones to escape pods in size (depending on gender), and are developed in special bays in the females hangar. See Link (Coming soon)

Both are naturally equipped with powerful thrusters in their wings and hip panels the power drive on their wings is capable of space jumps but takes a lot out of the Dro'ca to use.

Both are also equipped with Ion cannons in their mouths just under their tongues, it fires an intense Uranium Ion blast using residual energy collected from their Fusion Reactors.

Given the nature of their bodies, the Dro'ca determine their architecture but generally look like standard Starship interiors, they do have biological systems as well, which most of their biological vitals are found in their chest as their mechanical necessities are found in engineering where ever they decide to place it in their bodies. When you are near their core you can hear their heartbeat, but they do try their best to silence the sound.

When in Ship mode (as displayed here) they will keep their hands up to shield their eyes and rely on sensors to see around their peripherals.

Nil Mode:
Nil ships are Dro'ca that had their Intelligence erased, either by accident or due to punishment of a rogue ship, leaving them as mindless husks, they are manually controlled by a Captain or Pilot.

Humans exposed to the powerful features of a Nil are addicted straight away, and usually end up with the person being fully integrated into the ships AI matrix, as a result some Dro'ca will have Male Intelligence for a Female ship or vice versa.
