Devimon was the very first evil Digimon the DigiDestined had to face. He was responsible for all the Black Gears that corrupted many good Digimon including Meramon, Andromon, Monzaemon, Unimon, Frigimon, Mojyamon, Centarumon, Whamon, and Drimogemon. Devimon did not create the Black Gears himself and their origins are not explained. He used Ogremon and a Black-Gear infected Leomon to attack the DigiDestined. Devimon knew what the children were capable of (although they had no idea themselves) and that they were going to eventually destroy him. Devimon split the children apart on severed chunks of File Island and then used his minions and various others to try and destroy the DigiDestined.

After Ogremon failed and Leomon was rid of his Black Gear, Devimon took matters into his own hands and he absorbed most of his Black Gears and grew into a giant. Not even the combined might of Greymon, Garurumon, Birdramon, Kabuterimon, Togemon, Ikkakumon and Leomon were able to take him down(this can be attributed however to the fact that since he was a giant the attacks had less afffect on him that if he was his normal size, at which combined they could destroy him. After all what is easier fighting someone who is the same size as you or a giant to you). After beating them, Devimon turned his attention to T.K., whom he said was the one responsible for his eventual destruction. And he was right as Patamon Digivolved to Angemon and vaporized Devimon with a suicide point blank "Hand of Fate" blast. Just as Devimon was dying, he gloated that Angemon wasted his life for nothing, revealing that there were far more powerful evil Digimon that still existed. But Devimon was unaware that Angemon would be reborn to accompany the DigiDestined to Server to fight the evils he spoke of.

Digimon Adventure 02
When the Digimon Emperor was searching for a final piece in the creation of Kimeramon, he found the Dark Whirlpool (a gateway to the Dark Area where evil goes). In a Mekanorimon, the emperor found the disincorperate remains of Devimon. Despite the warning of how powerful the dark powers in Devimon's body were, the emperor extracted the digital corpse of data that became Kimeramon's arms and the DigiCore (which held the powers of darkness in it). Devimon's influence caused Kimeramon to rebel against the Emperor, and his voice haunted the Emperor. His essence was certainly destroyed once and for all upon Kimeramon's deletion.

Digimon Tamers
During Vikaralamon's rampage, a Devimon was among the many Digimon seen through the rip in the sky.

V-Tamer
A bunch of Devimon worked for Daemon. The first Devimon seen was used by Neo Saiba against Taichi Yagami and Zeromaru in their first fight, Devimon can DNA Digivolve with Ogremon to form SkullSatamon which he used previously to kill Etemonkey the Etemon and then fought Zeromaru after MetalGreymon failed but it was defeated anyway. Other Devimon were with Neo during the invasion upon Lord Holy Angemon's castle where they, along with the Vilemon and Devidramon, were sucked into the Gate of Destiny made by Lord Holy Angemon. 2 others were killed by Zeromaru. A Devimon alongside an Ogremon were toasted by Callismon.

Trivia

 * The first (and likely most well-known) Devimon who appeared in Digimon Adventure is often considered to be one of the finest villians of the franchise. Unlike many of his fellow villians, he avoided many villian cliches such as claims of invulnerability. He is also infamous for attempting to murder the Digidestined in their sleep.
 * Devimon was one of the few lucky villians to get his own image song. It is entitled Dark Wing and appropriately ends in a chilling, villianous laugh.
 * Many of the Digimon villians are evolutions of Devimon. This list includes Myotismon and Daemon.
 * Kaneto Shiozawa, who voiced Devimon, was well-known for his rasping, rough voice. Unlike other seiyuu, he played both villians and heroes such as the scheming M'Quve of Mobile Suit Gundam and Ryo, one of the pilots of the Super Robot Dancouga. Devimon was his final anime role before his untimely death.
