Parasites. At the end of the kaiju’s turn, 2 (1d4) of each kind of parasite emerge or detach themselves from the kaiju’s body. They appear in a space that is within 10 feet of the kaiju. If no space is available, they fail to appear. They are considered part of the CR calculation for the kaiju, and therefore yield no experience points unless encountered independent of the kaiju host. These parasites act on the same initiative as the kaiju, and have the following statistics.
