The personality of these baddies is almost impossible to read since they have a completely different culture than our own. But, what can be determined is that they are quite ruthless. Having said that, they are not stupid, and will ally with humans if they face a threat too great to handle themselves.
Martian Physiology - The martians physiology is completely different from ours. They are squid-like beings with several tentacles in the place of legs and arms. Their physiology makes them extremely agile and acrobatic. They can perform high-jumps and contortions. They are probably stronger than humans.
Explosive Teleportation - They can teleport themselves by exploding their bodies and appearing somewhere else.
Their fighting style is extremely unorthodox since they use their tentacles, laser guns and even call other martians and UFOs.
