Gzlob

Gzlobs are a hardy race. Their skin is tough and rubbery, and can resist high velocity shell impacts or electrical discharges. They come from a very large, dense world, and as such have what appears to be abnormal strength for their size. They do not breathe planetary atmospheres, and have no adverse reactions to extreme heat, cold, or pressure. They are thus able to survive in any number of hostile environments, including at the bottom of oceans or in the vaccum of space (for limited periods of time.)
