Dressed in a red Iron Man suit before jumping into a convoy on a mission to save a damsel in distress, nine-year-old Domenic has had his dream of becoming a superhero come to life.

Little Domenic, who suffers from cystic fibrosis, was playing near his home in Sydney’s south-west when a police helicopter landed nearby and asked for his assistance in saving TV reporter Hope Joy.

He was quickly whisked away to a ‘top secret’ operations room in Parramatta’s state crime command and transformed into his favourite superhero, Iron Man.

It was there that Domenic was briefed by NSW Police Commissioner Andrew Scipione that Hope Joy, a fictional reporter, had been kidnapped and was being held in the evil clutches of Ultron on Sydney Harbour .

"Officers have confirmed that Clark Island has been over taken by Ultron’s henchmen and Hope Joy is being held captive," said Police Commissioner Scipione told Domenic via video message.

"If I could make one wish it would be for you to help us Iron Boy."

From that moment, celebrities from around the world and around the country got behind Iron Boy and his mission to save Sydney city.

Walking through the doors of the Parramatta police headquarters, Domenic had a message for his foe:

"I am ready to get down to business," he said, shaking hands with Assistant Commissioner Mal Lanyon on the way.

And sure enough, the mini Iron Man was able to track down Hope Joy and valiantly rescue her from the evil Ultron, who had tied her to a tree.

"On behalf of a grateful NSW Police Force and indeed the people of Sydney, I would lie to thanks Domenic for his tremendous efforts today," Commissioner Scipione said on Thursday.

"It can't be easy dealing with an illness like his and we feel privileged to be able to work with Make-A-Wish Australia to ensure his wish to be a famous superher came true," he added.
