(goobs are alien parasites and they go inside animals and transform them into dark human-eating beast and they are called goobians after entering an animal. After entering an animal they turn into black goo like monsters that resemble the animals they control, they can't control humans because humans have stronger will power. So when a parasite enters a human, the human gets the parasite's abilities but still remain human, they use goobs to fight goobians, and some use goobs to make weapons)
