Venusian (The Critters)

Venusians are a sapient alien species from Venus which invaded and occupied Earth in the 21st century.

Biology
Venusians are bulky creatures with scaly skin, tentacular limbs, hooked beaks and slit nostrils. Their brains are built differently enough from Human brains that weapons that affect the latter are useless on Venusians.

Most notably, Venusians are endowed with phenomenal psychic abilities of their own. Their mere presence in a room affects Human brains in a mysterious way and induces paralyzing terror. They can use psychokinesis to physically destroy other creatures, tearing bodies apart, dismembering or crushing them.

Culture and society
Venusians are imitative by nature. When faced with unfamiliar technology, their first instinct is to investigate and dismantle it so that they can learn how to replicate it.
