Chryssalis Queen

Intro Alien kaiju is not just xenomorphs, the formidable bug race Chryssalid! When a Chryssalid kills a human (a civilian or a soldier), it will implant an embryo in them. This causes the corpse to rise up as a Zombie in the next turn, which will spawn a "Chryssalid Hatchling" after three turns. Hatchlings possess behavior and statistics identical to adult Chryssalids, but have a visually lighter color of chitin armor which changes to the usual purple within a couple turns. A newborn Chryssalid can move and attack the turn it emerges. Chryssalids can also use sufficiently large bioforms (like whales, bluefin tuna and sharks) as incubator hives. and here comes the titan sized queen of chryssalis, as a queen she didnt just kill to propagate, but also lays eggs of chryssalids, makes the swarm counts to legions in no time.
