The Zerg Tribe, Royal. The Royal Zerg Bloodline is exclusive to just three Zerg tribes. The Blue Morpho Butterfly Tribe, the Apollo Butterfly Tribe of the Zerg Empress Family, and the Monarch Butterfly of the Zerg Emperor Pure lineage are the bloodlines of the former Zerg Emperor's brother. The Monarch Butterfly Bloodline is thought to be the rarest of these three tribes, as only the most powerful male Zerg is able to awaken it.
It is reported that the former Zerg Emperor changed his Blue Morpho Butterfly bloodline to a Monarch Butterfly bloodline. None of the male zergs had awakened the Monarch Butterfly Bloodline since the Zerg Emperor and Zerg Empress had died. The Zerg race lost track of this tale, which is why the Blue Morpho Butterfly Bloodline is significant to the insect race.
