Lennox Lewis has told Tyson Fury to tone down his antics after he won the world heavyweight title.
The 27-year-old beat Wladimir Klitschko in Germany in one of the biggest upsets in heavyweight history with a unanimous points decision on Saturday to claim the WBA, WBO and IBF titles.
Fury dressed as Batman in the run-up to the fight and was involved in verbal spats with Klitschko, labelling him boring and robotic as well as saying he was only interested in breaking his face.
He also sang Aerosmith's 'I Don't Want To Miss A Thing' in the ring after victory in D?sseldorf and made homophobic remarks in a newspaper interview in the build-up to the fight, but former heavyweight champion Lewis has warned Fury he is now a role model.
"Now he's champion he has to behave himself a little bit more because there are a lot of kids and people looking up to him," Lewis told BBC Radio Five Live's Sportsweek programme.
"There are a lot of different boxers and people who will have a lot of things to say about him. If you allow (Fury) to say what he wants without coming back then you are soft to him. He won't respect you unless you directly come back at him.
"But he's a different character in the heavyweight scene. His character captures the imagination of people."
Ex-WBA champion David Haye, who is coming out of retirement in January against Mark de Mori, knows Fury must be careful but believes he is good for the sport.
He said: "It's a fine balance with what you say to how you are portrayed and being a role model and enthusing the kids in a positive way.
"It might be a bit negative from time to time but it makes you laugh and smile and that's better than being bored to tears by Klitschko."
The defeated champion may exercise a rematch clause to fight Fury again but Haye, who lost to Klitschko in 2011, has warned the 39-year-old he must change his style against Fury to stand a chance.
"I can't see Klitschko going back in the ring and doing that again. He had zero success bar the last minute and a half of the fight. I had Fury winning so many more rounds, I don't know why it was so close on the scorecards," Haye added on Sportsweek.
"I hope he (Fury) can win the rematch again and bring the titles back to Britain a free agent to fight the best possible fighters.
"It throws the division up in the air and makes it so exciting.
"Every fighter in the heavyweight division will have their guns pointed at Tyson Fury. He said he was going to do it and how he was going to do it. I didn't believe he had it in his arsenal to beat Klitschko but he proved everyone wrong."
