Balotelli was responding to comments made by his agent Mina Raiola, who compared his client to the fictional character created by J.M. Barrie who could fly and refused to grow up.
"I think these are metaphors for Mario the person, not Mario the footballer. I think I'm a man - I don't think I need to say it, but I am.
"I could be Peter Pan in that I do things my own way and I'm very free, but I think I'm more of a man than Peter Pan."
After a slow start to his Euro 2012 campaign, Balotelli found the net in Italy's final group game against Ireland, and the Manchester City striker said he was looking forward to playing against his club team-mates Joe Hart and James Milner on Sunday.
"I hope it's going to be a good match and I think it's going to be fun to play against my team-mates. They know me and I know them, so I hope that they're going to be nice.
"But even if they are my team mates I hope they are going to lose."
"Lucky him, he knows two Mario Balotellis," the striker quipped.
"They play within a space of 40 yards, we need to make sure we stop them from playing football," he said.
"The side we are going to take on has a lot of characters, it's going to be a meeting with a very tough side. We need to go into the game without any fear, we mustn't have any psychological hang-ups."
"I think he has a bit of a muscle problem but he's trained with his team mates today and is available for selection tomorrow. We'll make a tactical choice on that."
Andrea Barzagli said he and his fellow defenders would have to stay focused if they are to shackle England's Wayne Rooney, who returned from suspension to score in England's victory over hosts Ukraine.
"How do you stop him? As a team we can stop him, because there's four of us at the back. It's a team effort, we know just how good Rooney is and just how good England are as a side. We'll have to be 100 percent focused."
