I posted this idea once like 2 years ago, but it's kinda forgotten so...
I thought of a new kind of siege infantry for the Epsilon, I guess that it would PsiCorps the best (CLAIstar is probably facepalming now). I swear it's coincidence, I wasn't a PsiCorpsboo when I first had this idea. Anyway. Let's call it the Epsilon Juggernaut. Appearence wise, a big, bald guy, maybe with a breathing apparatus (think of Bane), some medium flak armor and robes covering his body, with a psychich amplifying device attached to his spine, similar to those that can be found on the backs of Initiates, although larger and more prominent. The Epsilon Juggernaut would attack by hurling massive blobs of destructive psychic energy over large distances, ie: miniature Raseph ball-lightnings. They could be shot down, easier than those fired by the Raseph, but the Juggernaut himself would be cheaper, and land-dwelling (or alternatively, levitating, just to fit better in the PsiCorps arsenal). He should be somewhat slow, expensive, but surprisingly durable, although not as much as the Stalker. A secondary, "psychic lightning" attack with (very) short range is optional, to fend off attackers that are within the minimum range of his primary attack. Now, because the Juggernaut's primary attack would look a bit like the "spirit bomb" in DBZ, I think it would be adequate if he had the attack voice line "GIVE ME ENERGY!", amongst other obligatory memes. The unit's character should be overly violent and eager for destruction. Bellow is the description I came up with:
No talent is wasted in the PsiCorps. Those Initiates who show exceptional psychic might but lack the mental stability to use mind control and thus become Epsilon Adepts are trained as Juggernauts instead. After years of training and augmentation, these rare individuals become walking engines of destruction, able to amass large blobs of unstable psychic energy and hurl it at the enemy, not unlike Epsilon's infamous Raseph submarines. Although the projectiles can be dissipated by concentrated anti-aircraft fire, continously fending off the attacks of multiple Juggernauts is next to impossible. When threatened at close range, the Juggernaut won't bother with collecting his energy into a ball-like form, but instead he will outright unleash it at the unfortunate offenders, in a lightning-like attack that can evaporate weaker foes in an instant. Despite his enormous power, the Juggernaut is still easily overwhelmed, so it's the best to keep him in the company of other units who can support and protect him.
I like this idea. It'd be especially cool if it floated and replaced dunerider for Psicorps.
