Yorik - et The yorik - et , referred to as a coralskipper or skip by New Republic forces , was the Yuuzhan Vong version of a starfighter during their invasion of the galaxy . Characteristics . The yorik - et was a bioship made from yorik coral , since the Yuuzhan Vong despised mechanical technology as an abomination . It was grown instead of manufactured so no two coralskippers looked alike . Despite this , every coralskipper shared some basic features , such as a dark canopy , and a triangular body . The coralskipper ' s pilot could communicate with the craft via a special mask called a cognition hood at the cockpit . The coralskipper ' s weapon was a Yaret - Kor , a small appendage at the front of the vehicle which released a searing magma rock that could seriously damage enemy craft . The coralskipper also possessed two plasma projectors at the front of the ship , sometimes referred to as ' rock spitters ' . The coralskipper refueled and rearmed by eating rocks , small asteroids , and stellar debris . However , like any living organism , coralskippers aged and died . Also , hidden beneath the front of a yorik - et was a small creature that resembled a heart called the dovin basal . Because it was living , it pulsed and shuddered constantly , similar to a Human heart . The dovin basal was the most important part of the bioship because it functioned like a miniature black hole , creating a powerful supergravity field when activated . This field could be used to overload the shields of an enemy starfighter and could also act as the coralskipper ' s own shield by drawing laser fire and missiles into the yawning maw of the miniature singularity . Like all classes of Yuuzhan Vong spacecraft , the coralskipper utilized the dovin basal as a means of propulsion , which became a weakness to exploit when destroying the coralskipper . When propelling the craft , the dovin basal was not capable of defending the craft as efficiently as it could when remaining stationary . Coralskippers were strictly space vehicles , and performed poorly in planetary atmospheres . Coralskippers were not capable of traveling for long - range travel in space and had to rely on a larger vessel to transport them across long distances . History . The first recorded cases of of the Yorik - et craft was during the initial stages of the Yuuzhan Vong invasion in 25 ABY , which was spearheaded by the Praetorite Vong who had brought thousands of such fighters onboard their worldships to the ice planet of Helska IV . The Dozen - and - Two Avengers first encountered the craft and were left with only a single survivor of the attack when the vessels ' dovin basals were used to strip the shields from the enemy craft . They were later used in an attack on the planet Dubrillion , though they were repulsed by the planetary defenders . A single downed Yuuzhan Vong craft was later examined by Lando Calrissian ; the evaluation gave an insight into the extragalactic invaders and their technology . During the Battle of Helska IV , the coralskippers were coordinated by a Yammosk , which destroyed numerous New Republic starships before the ice planet of Helska IV was destroyed in a New Republic attack . These vessels fought throughout the Yuuzhan Vong War . In the last year of the war , a new type of fighter was developed to support Supreme Overlord Shimrra ' s Slayers .
