Go into league challenge on the main menu.  Beat all  
categories and at the end you will get Joe Bruiser if 
you beat him.  But that's not all.  After you beat Joe 
Bruiser there will be a different category in league 
challenge.  When you go into that category remember one 
thing it takes over an hour to finish it.  But if you do 
finish it you will be versing Blackwidow.  Even though 
she's a girl she makes a great tag team partner.  That's 
why you want to beat her.

When your'e wrestling have your spirit meter on. When ever 
you can move around the joystick. When you see your spirit 
meter says SPECIAL! Put your opponent into a strong grapple 
and move around the joystick and you will do your special 
move. Like DDP does the Diamond Cutter and Giant does the 
chock slam. Do some of these correctly and sometimes you 
will knock your opponent out cold
