Devimon

"For I am Devimon, ultimate ruler of the demon underworld. You must obey my every command."

- Devimon "Feel the Touch of Evil!"

- Devimon unleashing his Touch of Evil attack. "You have used up all your power. That wasn't very smart, Angemon! Now you're no use to anyone. You can't get away from the dark forces. Evil is everywhere, so don't savor your victory. There are other Digimon who are just as powerful as I am. Some of them are just stronger. I wonder what you'll do when you run into them. You haven't won at all! What a waste of time! Hahahaha...."

- Devimon as he was dying.

Devimon, also known as Darkmon in Japanese version, is the first major antagonist in the Digimon Adventure anime, though he only appears in four (five, if one counts his appearance after death) episodes. Devimon is also a minor villain in Digimon Fusion.

Devimon is a Champion Digimon, although a very powerful one, rivaled only by Angemon. He is a jet-black demon with horns and red eyes and two wings with holes in them. He always has the recurring Mark of Evil symbol on his chest.

When he fights the DigiDestined in giant form, his wings spread out like VenomMyotismon's.

Digimon Adventure 01
Devimon discovered the Black Gears and implanted them in good Digimon to turn them evil. Victims included Meramon, Andromon, Monzaemon, Unimon, Frigimon, Mojyamon, Centarumon, Whamon, and Drimogemon. The most notable of his victims was Leomon; while Leomon and Ogremon were fighting, Devimon commanded them to work for him. It took little convincing to get Ogremon on his side; however, Leomon was good so he refused to work for Devimon, until Devimon used the Touch of Evil to turn Leomon evil.

The Digidestined confronted him on top of Infinity Mountain, and even used their Digivices to free Leomon from his control. Devimon used his power to break File Island apart and scatter it all over the sea. He also turned Leomon evil again. After fighting off several Digimon, most of them victims of the Black Gears, the Digidestined (minus Joe and Sora) fought Leomon at Primary Village, where Leomon was attacked by more Black Gears, making him bigger and stronger. But they drove all the evil out with their Digivices. Leomon told them that the only way to restore File Island to normal was to defeat Devimon.

Naturally, the Digidestined chose to attack him. Back at his secret Castle atop Infinity Mountain, Devimon absorbed Ogremon and all the Black Gears, transforming into a much bigger form. Although they were able to get some shots in, Devimon gained the advantage over all of them, using powers of pure evil. Leomon was sent flying far away by Ogremon, who kept on jumping out of Devimon's chest. Devimon eventually turned to TK, whose Digimon Patamon had not participated in the fight due to his inability to Digivolve.

It was said that the smallest Digidestined would destroy him, so Devimon tried to crush TK but Patamon jumped in front of him and was caught in Devimon's fist. However, it was at that moment that Patamon Digivolved into Angemon. In the classic angel vs devil battle, Angemon knocked Ogremon out of Devimon and put all his power into a Hand of Fate attack, which he used to destroy Devimon. Angemon appeared to be destroyed as well, but de-digivolved into a Digi-egg. The next time he became Angemon again was to fight the even more sinister Myotismon.

Digimon Adventure 02
When the Digimon Emperor extracts DNA from Digimon to make Kimeramon, he enters the Dark Whirlpool, where he finds the broken remains of Devimon (who is said to have created the Whirlpool) and absorbs him, ignoring his warning that he cannot control the power of darkness. The Dark Whirlpool is believed to be caused by Devimon. Devimon's voice continues to taunt the Digimon Emperor, and his influence causes Kimeramon to rebel against him, but he is once again destroyed when Magnamon obliterates Kimeramon.

The exact nature of his reappearance is unclear. It could be that, like Wizardmon and Myotismon, he became a ghost after his death and haunted the ocean, creating the whirlpool to the powers of darkness. It is also possible that the Dark Whirlpool leads to the Dark Area (Digimon hell), and Devimon somehow opened the portal from within (supported by the ghostly apparitions appearing in the whirlpool).

Digimon Fusion
In Digimon Fusion, an army of Devimon served one of the Dark Generals; NeoMyotismon, along with his female version, LadyDevimon. they along with the army of LadyDevimon were absorbed by NeoMyotismon so NeoMyotismon could become NeoMyotismon Darkness Mode.

Personality
A Fallen Angel type Digimon who wraps his body in jet-black clothes. He was originally a pro-brilliant Angemon, but soon the space of the Digital World became distorted, and he fell into the newly-formed Dark Area and became the demonic Digimon we see today. On his chest is embodied greatly a mark of evil, proof of his wicked wellbeing. He has a cunning and brutal nature, but he is also very superior and intelligent. It is said that should you be influenced into staring at his shining crimson-red eyes, he will control your mind. His special attack is "Death Claw", which stretches out his elasticized arms fully and stabs them into the opponent's heart.
