Diablon

thumb|300px|right|Sonic and Diablon fighting Shadow. The U78-X/D Diablon was a prototype energy-charged weapon built by the Guardian Units of Nations and one of the final bosses in Shadow the Hedgehog.

History
Diablon was piloted by the Commander (possibly remotely) and appears after the dark mission is completed in the levels GUN Fortress, Black Comet and Final Haunt in story mode. The Commander used it to try and gain revenge by fighting alongside Sonic in the hopes of taking down Shadow, only for them both to be defeated at the Ultimate Lifeform's hands by exploiting Diablon's weaknesses.

Abilities
Diablon was fitted with an electromagnetic barrier that, when activated, deflected firearm attacks, laser blasts and even physical blows. However, when the shield was shut down so Diablon itself could attack, it was left wide open to any of these. In terms of weaponry, it had a laser cannon secured on its forehead that shot out a laser beam in whatever direction it wanted and also had an antimatter cannon, which could destroy anything in a certain radius around Diablon after charging up. Apart from that, the only abilities Diablon had were hovering and moving around in the air by using its jet boosters and swiping at enemies with it hands.

Trivia

 * In all three endings in which Diablon was defeated, it was seen disabled but mostly intact. Its current status is unknown, as none of the optional Shadow the Hedgehog endings have been confirmed as canon.

Etymology

 * Diablon's name derives from the Spanish word for devil, diablo. Perhaps coincidentally, whenever the Commander takes a swipe at Shadow in Diablon, he says "Hold still, you devil!"
