"Even the most sweet-faced little goody-goody has a drop of evil in his heart. I can make that little drop in you expand and expand and expand until... You're blown to bits!!!"
Devilmite Beam (アクマイト光線) is Spike the Devil Man's ultimate attack that transforms an opponent's own negative thoughts into destructive beams that can annihilate anything in their path. However, it only works if there are negative thoughts in the target's mind to begin with. Due to this, outside of the video games, it is an all-or-nothing attack; it is either a sure-kill or a mere light show.
"It is a force of unimaginable evil, that had destroyed more lives than any war or pestilence combined. Long ago there was a mighty-but-compassionate warrior. His power was beyond measure, yet many foolish upstarts tried to destroy him, in hopes of making a name for themselves. They were all unsuccessful, until one day, the Devilman appeared. Knowing he could not compete against the warrior's strength, the Devilman attacked using his mind. He discovered he could exploit his opponent's negative thoughts, no matter how faint, and convert them into an energy beam of immense power, the Devilmite Beam (Akkumaito Kousen).
It amplified any dark thought (anger, malice, aggression) and caused it to expand until his opponent's heart, literally exploded! It was the death of a great hero, and the birth of an even greater evil.''"
When Goku was fighting, and overpowering Spike in Fortuneteller Baba's challenge, it seemed that Goku would become the Devilmite beam's next victim, however Devilman (and Goku's friends) were in for a surprise. Devilman attempted to use this attack ("twice") to destroy Goku, but it failed ("both times"), as Goku had no negative thoughts to exploit (as Goku is pure hearted).
Appearances in games
The attack also appears in Dragon Ball: Advanced Adventure as Devilman's strongest attack. The attack takes a long time to charge and perform, and Devilman is completely defenseless while using, meaning that enemies can attack him, preventing him from completing it. However, the Devilmite Beam instantly kills the enemy if it lands.
The technique is Devilman's Ultimate Blast in Dragon Ball Z: Budokai Tenkaichi 3. The Devilmite Beam is unique as its strength and damage are determined by who the opponent is, and whether or not the opponent is equipped with certain specific Z-Items (potaras). There are two Z-Items that alter this attack's damage that are:
- Lover Of Justice (Good Characters Only): A Z-Item that can be equip to characters with a Good affinity. The Devilmite Beam's damage is reduced when equipped (meaning they take less damage from this attack).
- Evil Ambitions (Evil Characters Only): A Z-Item that can be equip to characters with a Evil affinity. The Devilmite Beam's damage is increased when equipped (meaning they take more damage from this attack).
Some characters are immune to the Devilmite Beam, because they are pure of heart (like Goku). However, if a pure-hearted character like Goku transforms into either a Great Ape or a Super Saiyan, they can lose their immunity to it as these transformations taint the heart, meaning they will take damage from the Devilmite Beam. It also does huge amounts of damage to pure evil characters like, Evil Buu, Janemba, Hirudegarn, and Omega Shenron (and basicially does decent Ultimate damage to every villain in the franchise, past and present, including Good affinity characters with some sort of a villainous bent, such as all forms of Vegeta with a Good affinity [or not]).
Also in Budokai Tenkaichi 3, in Devilman's "What-If Story", Spike the Devil Man fights Frieza and King Cold, who are waiting for Goku to return to Earth so they can kill him. He is surprisingly able to defeat the pair (as well as two other soldiers), all thanks to his signature Devilmite Beam; Spike says to King Cold that the reason of how he managed to kill Frieza so easily was due to his evil-filled heart.
The Devilmite Beam also appears in Dragon Ball Z: Dokkan Battle as Devilman's Super Attack, where it inflicts huge damage to the opponent. However, Devilman's unique Passive Ability, "Demon From Hell," gives the beam a "very small" (around 1%) chance of inflicting 99,999,999 damage, enough to instantly defeat even the game's strongest opponents.
- When this technique failed on Goku in the manga, Fortuneteller Baba compared his mind to that of an infant or an animal, so it can be assumed that this technique would fail on infants and non-anthropomorphic animals as well. This is likely because both do not have any complex or impure thoughts.
