What does it mean?

Its a fan done bit of artwork.

Basically its the dude in my profile pic and its part of his mythos.

Oh I see. And who is he?

This chappy.

Yes, my phone won't open that.

Well, basically he's a genetically modded super-soldier-angel in outer space.

He has a legion of similar warriors all created from his genetic code.

When he was killed by his brother his final moments were imprinted on them causeing mental meltdowns and massive bezark episodes.

And there we have it.

I dig it. Nice dude. Nice!

Hhmm. Ok!

Where are you having it done? Or have had it done, whichever :0

Its on my upper arm - just below the shoulder.
