WWE could use the fact that he is "out of shape" and make him debut as one "non wrestler" guy trying to fight in pro-wrestling for any reasons. Seriously WWE needs this average joe gimmick. He would wear regular clothes (worn out jacket, ripped jeans) which will hide his love handles.
It would be frankly different and shine in the middle of trunks wearing and bodybuilded wrestlers. Santino Marella debuted as one outsider. Ohno can do it too.
One gimmick possibility is the "crazy hobo" gimmick. Ohno could actually believe that he is Jesus and try to instill morality into WWE. He would be on crusade agaisnt Heels and Evil.
Seven deadly sins :
- Lust : Cena, Ziggler and AJ (burn the witch)
- Gluttony : Mark Henry, Brodus and of course Ryback (just see on youtube of much he can eat)
- Greed : Del Rio
- Sloth : not sure yet
- Wrath : Daniel Brian and Kane
- Envy : CM Punk (about respect)
- Pride : Cesaro and CM Punk
His main target would of course be Cesaro.
He'd be all strange and act like one benevolent cult leader or priest. He would later wear brown robes and sandals and talk bible stuff while showing off his crazy side by wrestling like a mofo in the ring making people question if its just a mind game on his opponents.
The new Mordecai except that Kassius Ohno has the perfect look.
