Cylon Basestar Battlestar Galactica
Basestars were developed during the Cylon War Era. At this age, the Cylon-Tech, Basestars were constructed with the most advanced, hardened organic matter operated by organic crews, Cylon individuals called Hybrids.
Fleet of these Cylon Basestars continued to harass Galactica in “The Fall of Twelve Colonies”
Since these Basestars are organic by nature, damage can be repaired by itself like wound-healing process or system regeneration.
