When Soa Palelei walks towards the octagon he looks upbeat.
He's a placid guy, but when the bell goes the Australian UFC heavyweight takes on his alter ego, which is also his nickname: "The Hulk".
Newcastle-raised but now based in Perth, the 36-year-old came through a rough upbringing where he even spent time living under someone's house after running away from home.
When he was at home, Palelei said his family regularly survived on little more than a loaf of bread and a jar of jam and that background helps him channel his focus towards his next opponent in the cage.
"When I'm in there I kind of think: 'This kid stole my lunch when I was at school'. I was pretty poor back in the day," he said.
