So you thought you were a bad mother fucker. 
You've seen all the cage matches on repeat and you could swear you'd beat the shit out of anyone that looks at you funny. 
And then, your big opertunity came in the form of a big fuck off yakuza messing with someone he owed money. 
So you strut up. and out of nowhere throw ALL your weight behind your punch. You strike hard. Perfect form. You aim for the solar plexus and you're ready to rock the world

And just like that, you're nobody again. Someone forget to tell you if the guy you're hitting is 150 pounds up on you of pure cyborg muscle..maaaaybe you should think twice yeah...?
