Consider what we know.
1. Can chop head-to-head against the best of them.
2. Can brew up a fine 3D render seemingly easier than some folks breathe.
3. Has the ability to find obscure photos based off a tiny cropped sample
4. Seems to know a lot about programming, tech, and all things geeky
[added items per submission]
5. Knows how to calculate the angle of light being reflected off venus and refracted by swamp gasses.
6. Is always there to help! In silence... via pm.
7. Guards actual identity like it's the recipe for the 11 secret herbs and spices.
8. Knows what an "Green Arkleseizure" is apparently.
9. He's a very naughty boy! (according blue_lurker, talk about pot calling kettle)
10. The mere discussion of vokaris is enough to invoke an identity crisis in ReyRey and the appearance of muppets.
11. Throws ReyRey into Oedipal fits apparently.
12. Apparently discussing vokaris scares the ever lovin' crap outta the PSC crowd.
13. Vokaris farts at breakfast (did I get that right?)
14. Time travel must be another of his freakin' alien powers (thanks to Al for pointing that one out).
15. Vokaris can identify obscure fonts faster than reinman can write a witty polka jingle.
I think vokaris is an extraterrestrial (semantics fixed for Martex's benefit).
Post your own hypotheses on the nature of the vokaris creature.
