The Castor (キャスター kyasutaa), formerly known as the Gemini Blue, is one of two guest fighters from the relatively obscure arcade shmup Gemini Wing, the other being the Pollux. A long time ago, in Xeno Fighters R's early versions (V.A.F. Squadron), the two Gemini Wing ships were playable, called Gemini Blue and Gemini Red. Their weaponry in those early versions were completely original, soon becoming the weapon sets of the Phyxius and Zaiva respectively. The Gemini Blue and Gemini Red make a return in Xeno Fighters R with names from the twin brothers in Greek and Roman mythology associated with the Gemini constellation. They were given weaponry based on attacks found in Gemini Wing.
The Castor and Pollux are the only ships whose main shot is never upgraded when you collect powerups. To offset this, the subweapons of these two ships are quite powerful, although some of them are rather awkward to use. The Gemini Wing ships are also the only ships (so far) that have a dual-bomber system.
The Castor is an average-speed fighter. Its subweapons are based on the Gunball powers. It is not particularly powerful, but fully powered up Lasers and Missiles provide a lot of screen coverage.
3-way Shot: This weapon pierces through enemies. However, it fires quite slowly and offers almost no frontal attack capabilities. When powered up, only the flanked shots gain power. Effective use of this weapon is to use the flank shots to deal the most damage to large enemies, especially bosses.
Homing Missile G: Standard homing missiles with a fairly high damage rating. Fully powered up, the Castor shoots out 8 of these missiles at once.
Dual Gunball Type 1: Deploying this bomber while holding down the Shot button releases a Wide Beam, which extends the full width of the screen and sweeps upwards quickly. Not a particularly powerful Bomber, but its quick deploy time makes it an effective panic bomb.
With a neutral press of the Bomb button, a Spark Hurricane is released. Circular sparks rotate outward from the Castor, damaging enemies and canceling out bullets. The individual sparks are not too damaging, but overlapping an enemy while using Spark Hurricane deals tremendous damage to large enemies.
A Gunball icon behind the ship denotes what Bomber will be active.
Standard Raiden F: This is the standard Slave type used in the Raiden Fighters games.
