Ugh, trying to put out a suggestion for a new alien type but I don't know what-
...

[b]Ethereal Commando[/b]
[i]The Ethereal Commando is physically weak, only slightly stronger than the average Ethereal. Their bodies have atrophied up to the point where the only thing keeping them alive is their mental ability. Some of their organs are underdeveloped with some sensory organs not working at all, requiring the need for their specialized armour. Their brain, however, is very well developed and requires the largest blood supply in their body.

It appears as though the heavy Alloy armour these Ethereals use are powered completely by their Psionic abilities. It seems like the Armour is integrated inside the body, much like a Floater. It strengthens the Ethereals muscles, organs and bones. The armour provides complete resistance to conventional bullets, and lasers, only damaged by Plasma.

The trade off for these enhanced physical abilities, however, is weakened Psionic strength, as it is used to power the armour. (Though, their psionic abilities are still a force to be reckoned with.) To compensate, there are various weapons in the armour. Further research is required." [/i]

Basically, ETHEREAL WITH POWAHD ARMAR AND GUNZ. Because fuck fairness, this is X-Com.
