The 21-year-old brother of Canterbury's Dally M medal winner Ben Barba has signed to play for NRL rivals Gold Coast.
Marmin Barba, who like his talented older brother is capable of playing in the halves and at fullback, signed a two-year deal after playing in Parramatta's Toyota Cup team this season.
The youngster, who is recovering from a knee reconstruction suffered in early 2012, was also diagnosed with lymphoma cancer in his groin in 2010.
The Titans farewelled co-captain and star halfback Scott Prince last month, releasing him from the final year of his contract to play with local rivals Brisbane, but chief executive David May said Barba's signing was more to do with the club's long-term plans than any quick fix he might offer in 2013.
"It's probably a decision that is more about the future than necessarily today," May said in a statement.
"He'll train with us and hopefully prove what he's got.
"It's an investment in the future so it's great to have someone as exciting as him around the club.
"We wanted to give him a chance and two years really is probably a window that you want to give somebody of his age the opportunity to show what they can do."
May said Barba had serious potential.
"Marmin is a real prospect, he's obviously got a great pedigree and by all accounts is one of the bright young future stars of the game," May said.
