X

"AHAAAA! As usual, I've outsmarted yet ANOTHER opponent! You can never defeat me: PILOT X! If sales are good, I'LL BE BACK! And if they're not, I'LL COME BACK ANYWAY! Just you wait and see! I'll be back, you puny evolved monkeys! Do you hear me?! I'LL BE BAAAAAAAAA- *hit by an asteroid*"

- Pilot X, after having been defeated



Description
X is both the final mini game and final boss.

In Adventure Mode, the mini game is preceded by a cutscene involving Pilot X unmasking himself and challenging the chosen racer to a battle in outer space. He or she is then spirited away into the void - regardless of whether or not the challenge was accepted-  and forced to fight X's battlemech: Robo X. The boss battle proceeds as follows: Successful completion of X unlocks Pilot X as a playable character in Race Mode. In Adventure Mode, the chosen flyer's story is resolved and followed by the closing cutscene.
 * Robo X releases a pair of saucers and wields a yellow ball of light that produces an electrical field when thrown. Impenetrable save for a single circular hole the flyer must guide his or her plane through in order to avoid sustaining damage.
 * Robo X wields a red ball of light that summons a swarm of robot drones when thrown. Dispatching a wave of drones provides the flyer with a single unguided missile.
 * Robo X throws a tantrum and bull rushes the flyer - costing him or her a life if he or she is unable to dodge away in time.

Trivia
Pilot X is referred to as the "mastermind" of the Freaky Flyers race in the Mini Game level selector. This is at odds with the lyrics of the song "Pilot X" which say that X heard about the race from "a far-out galaxy"  - implying that it had already been created before he arrived.
