This breed of Chimera were spotted first within the Raccoon City base in 1998 but afterwards, were thought to be extinct though two years later they reappeared inside of the North Carolina base. These Chimeras, like there counterpart inhabit the basement of the North Carolina base and lay there eggs. Several were killed by Kevin Coen and Julia Hayes in the outbreak of the North Carolina base. They continued later to be spotted in several other bases but now are confirmed extinct.
