When the Yuuzhan Vong invaded the galaxy, Suvar and his brother Cham were with the Mandalorian bounty hunter and Mandalore Boba Fett in 24 BBY as part of a group known as the Mandalorian Protectors. Piloting Gladiator-class assault fighters during the war, the Dettas joined Fett on a mission a week after the invasion of the planet Helska. Assaulting a space station in orbit over Birgis, Detta and the other Mandalorians occupied the station while the Yuuzhan Vong invaded the planet.
Despite appearing to work for the Yuuzhan Vong, the Mandalorians were supplying information to the Jedi Order through Jedi Knight Kubariet. Upon first meeting the Jedi, Detta had tried holding him down only to be disabled by a knee to the groin. Kubariet later agreed to cooperate and the mission to gain the Jedi's trust was successful.
