The second novel in the 2010 - 2012 series "" was "Zero Sum Game", written by David Alan Mack. In the novel, it is established that the Breen Confederacy is made up of many separate species, all of which wear suits to disguise their appearances and subsume their identities into the Breen name. The known Breen species are:  In "", 1997 the third-season finale of "", Lieutenant Tuvok states that the Breen use organic technology in their ships when discussing the bio-organic starships of Species 8472. Their ships are armed with cloaking devices and disruptor-type weapons, according to "". In "Star Trek Generations" Riker mentions the Breen as one of only three species with access to Type-III hand-held disruptors. During the Battle of Chin'toka, a Dominion War battle that occurred in the episode "The Changing Face of Evil", the Breen employ an energy-damping weapon that could shut down all systems on Alliance ships. The Klingons subsequently discover an engine modification that renders Klingon ships immune to this weapon, though it does not work on Federation or Romulan ships since they are powered differently. The Breen used this weapon to great effect, completely immobilising the USS Defiant, and a fleet of alliance ships, allowing the Breen to destroy them at their leisure. The helmet of the Breen suits consists of a visor that either glows green, or has small green and red lights on it, and a detachable "beak". The Breen's suits come in two types. The first is a standard suit that is worn by most of the Breen. The second is a more ornate version worn by Thots or other officials that has gold lining and distinctive gold stripes running down the top of the helmet and the "beak", as seen in later episodes of "Deep Space Nine", such as "". The non-canonical book "Legends of the Ferengi" claims that the Ferengi were sold warp technology by a Breen they called "the Masked Breen" (because they did not know the Breen all wore masks). In return, they gave the Breen both poles of Ferenginar, several comets, and a frozen moon. A Breen participated in the palio on Deep Space 3, according to "", a 1993 seventh season "Next Generation" episode. Breen privateers attacked Free Haven, a Bajoran colony, in "", a 1996 fourth season "Deep Space Nine" episode.
