They use long glass pipettes to extract blood from their victims, which they take directly into their systems. Extremely strong beings whom are able to move unaided in Earth's heavier gravity, possessing tentacles from which humans rarely escape once they've been caught.

Which are armed with heat rays, black smoke projectors, and mechanical tentacles. The invisible heat rays ignite buildings up to a mile away. Canisters release the poisonous black smoke which is rises up to 50 ft into the air, a viscous, clinging thick smoke.
