Enigma

Enigma (エニグマ) is an old cannon located in the Maverick Hunter's base that appears in Mega Man X5.

To stop the descent of the space colony Eurasia, X and Zero are sent by Signas to retrieve four devices in the possession of Mavericks that can improve the Enigma, increasing its chances of successfully destroying Eurasia. If the Enigma is not able to destroy Eurasia, the Hunters will use a Space Shuttle as last resort. The prologue for Mega Man X6 suggests that it failed to destroy Eurasia.

Trivia

 * The Enigma appears in the background of the first battle against Dynamo.
 * The Crystal Ball was mistranslated as "Orifalcon" in the English instruction manual.
