it starts with the berserker laying a cluster of about 30 eggs.
Stage 1 (infant) - Wretches (genderless)
Stage 2 (puberty) - Male = Drone/Grenadier - Female = Kantus
young adult - Male = Theron/Boomer - Female = Elder female (like skorge)
Full Adult - Male = Palace guard/Elder male (like RAAM) - female = Berserker
This whole theory just came out of boredom and noticing that the kantus/skorge has similar a segmented skin to berserkers. Does anyone else agree?
