That's still super... 
Seriously... 
Void Wolf as of right now has two options:
1) Strength/super factor
2) Stealth factor

Both of which are taken. 
We could try feral factor, but overall I think his character wouldn't work out too well. You're awesome dude, but so far you've played him as the not just distant or silent he's just not social... Which probably falls into the rule of no shyness. lol
