Chrysalid (Resident Evil 6)

Image of Chrysalid
After a J'avo is defeated, it will occasionally transform into a hard cocoon. If left alone, the cocoon will hatch into an advanced J'avo - a Strelat, Napad, Meset or Gnezdo! It is possible to destroy a chrysalid before it hatches, but due to their tough exterior it may take a lot of ammunition to do so.
