From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Devil Man (アックマン, Akkuman; FUNimation "Spike the Devil Man", Viz "The Devil") is one of Uranai Baba's champions. He is the strongest of her fighters until he is bumped down one rank by Grandpa Son Gohan.
Devil Man's Japanese name is a pun on the word Akuma, or Devil in English.
 Early life
 Dragon Ball
Devil Man fought against Son Goku in Devil's Toilet somewhere within Uranai Baba's Palace. He gave Goku a run for his money and tried to blow him to shreds with his Devilmite Beam, but unfortunately he did not know that Goku had a pure heart.
 Dragon Ball Z
Devil Man was killed from either Super Boo's Human Extinction Attack or when Kid Boo destroyed Earth. He was revived with the rest of Earth's population by Polunga and gave his energy to Goku's Super Genki Dama after Mister Satan asked for everyone's energy.
 Video games
Devil Man appeared in Dragon Ball Z: Sūpā Gokū Den: Totsugeki Hen.
Devil Man appeared in Dragon Ball Z: Budokai Tenkaichi 3 as a playable character.
In Dragon Ball Z: Budokai Tenkaichi 3, there is a "what if story" where he fights against Freeza and Cold (who are waiting for Goku to return to Earth so they can kill him). Devil Man is surprisingly able to defeat the pair (as well as two other soldiers) thanks to the Devilmite Beam.
- Note: In Budokai Tenkaichi 3, he is one of the stronger arena fighters and his Devilmite Beam is unique, as its strength damage is determined by who the opponent is and whether or not the opponent is equipped with certain Z Items (Potaras). Some characters are almost immune to the Devilmite Beam (like Goku) because they are pure of heart, however, if said character undergoes a transformation which taints the heart (such as turning into either a Great Ape or Super Saiyan), they lose their immunity, and thus can take some damage from the Devilmite Beam. It does deliver large ultimate damage to every past and present villain in the Dragon Ball franchise included in the game, with especially huge amounts going to 100% pure evil characters like Evil Boo, Janemba, Hirudegarn, and Omega Shenron. If someone uses the Devilmite Beam on another Devil Man, it leaves the hit Devil Man with only 1 HP if he had full health when the move connected.
There is also "special dialog" between him and Dabura if they fight against each other.
 Devilmite Beam
His ultimate signature attack, Muten Roshi stated that the Devilmite Beam was a force of unimaginable evil that was said "to have destroyed more lives than any war or pestilance combined". Roshi told an old story of a "compassionate warrior/monk" (and powerful martial artist) who many fighters (including Devil Man) sought to defeat (in order to build their reputation). Knowing he could not match the "warrior's great strength", he attacked using his mind. Devil Man used the warrior's own negative thoughts against him by firing a beam that amplifed any dark thought (anger, malice, aggression, arrogance, etc.) and caused it to expand until his opponent's heart literally exploded. The technique, however, is rendered totally useless if the person "doesn't possess a single negative thought" (as there are no negative thoughts for the beam to amplify and explode), such as pure-hearted Goku.
The Kaikosen is mystical energy attack that he fires from his hands that ensnares the opponent in electrical energy, temporary paralyzes the opponent (it can be used before firing the Devilmite Beam to ensure a direct hit).
