Normally, Painite has a reddish color, but the Painite in the DD:RS changes color and emits radioactive inner lights. In apparance, they come in stereotypical crystaline form.
It's very unique radioactive type creates millions of cells which infect the brain and start draining the brain from a low level of knowledge of anything not-supposed-to-be alive. When they make contact with something dead, the tissue, organs and flesh regenerate. As the parasites multiply rapidly, the body of their host grows. These parasites can't be spread on contact with non-infected creatures, or be passed down to offspring, which explains why Dodozilla's offspring don't grow to gigantic size. Anything infected keeps growing until the parasites are completely eliminated.
