Red orcs?
I actually am thinking that he's half-orcish myself though, haha. I'm really curious how he met up with Scar!
...and I am also psyched that you can help him out more, haha, his reaction to someone being genuinely nice to him is more than a little awesome. :D
I say the red orcs because their camp seems closer to Northcrest then the other clans, after all they have an outpost close by, and Tank has a similar demeanour to them with the whole boss theme and power hierarchy and he has the skill to go berserk during a fight, which is a skill only non-humans have used so far(werewolfs and orcs), also, his body type reminds me of the orc brute for some reason and the way he fucks you when he's dom top also reminds me of the orc brute, and that's about it I don't have many facts to support my theory so I'm going of a gut feeling.
I'm also dying to know what's their story I need backstory to live
Well You are right a lot things like:
He loves fucking I mean LOVES like the red orcs
He Does the hierarchy like Orcs way of Doing things
He got Mistreated because hes different like alot of people that aren't fully human like Ste's kids when they were visiting Bareshade for the first time.
He has those Fangs and the thing covering it like its for humans with non-human facial features.
A last when He Has the Biggest and Thicccest Dick ever like no human can feasibly use it he does.
Weird part is His skin colour is a human one instead of the Signature Orc colours like Green or Red. Not even a mixture of them like a lighter shade.
Heh, he's also pretty dang huge which helps show being at least partially non-human. It took me awhile to realize that his metal jaw is /probably/ covering up tusks.
I don't know about it being specifically red orcs, though. They're big on sex, but their biggest target seems to be fighting and strength more than that - particularly if their warchief is a paragon of their beliefs!
Granted, Tank does seem to like fighting as well, so the theory still stands. Or well, at least he's reasonably concluded that 'this is the one thing I'm good at' and sticks with it, haha.
Being bullied fits any group, though - humans tend to dislike nonhumans, and both of the orc tribes we've interacted with are very hesitant about there being humans about, so being seen as 'the other race' and not being the brightest bulb himself means he's likely to run into problems everywhere.
(Of course, /part/ of this might be that I play a dominant top myself, so I don't know how he rolls in other situations, haha)
Tank is awesome.
