Diablo is the main protagonist in Isekai Maou to Shoukan Shoujo no Dorei Majutsu (The Demon King). He claims to be the Demon King. This nickname aligns with his overwhelming strength in battle.
Diablo is capable of using various high-level magic with impressive destructive power. What are his strongest magic spells? Let's check out the full discussion below!
15. Magic Reflection
Magic Reflection isn't actually a magic spell, but rather a unique ability derived from a ring worn on Diablo's finger. As the name suggests, this ability allows Diablo to automatically reflect an opponent's magic aimed at him.
This ability often saves Diablo from unexpected situations. An example is when he was first summoned to another world by Rem and Shera. The summoning effect was supposed to make him a slave, but the effect backfired on Rem and Shera.
14. Super Mine
Super Mine is a magic spell that is very suitable for use as a trap. The spell functions like a mine embedded in the ground. When an enemy passes by, the spell automatically activates.
The explosion generated by Super Mine isn't particularly large. However, Diablo can create multiple traps at once, making his attacks more effective. He once used it against Garfold.
13. Dark Press
When activating the spell called Dark Press, Diablo creates a series of black spheres capable of generating a high-level gravitational field. He then directs these spheres towards his target.
Dark Press is very effective in immobilizing his enemies. Furthermore, the powerful gravitational pressure has the potential to crush an opponent's body and leave them feeling hopeless. This was clearly demonstrated when Diablo fought Gregor.
12. Aero Shredder
Next, there's an interesting magic called Aero Shredder. This magic allows Diablo to unleash a sharp whirlwind attack that can shred its target to pieces.
Aero Shredder is so deadly that it's considered the highest level of wind element magic. Diablo once used this magic against one of the Hunter Worms summoned by Gewalt.
11. Cross Blizzard
Diablo's next magic is Cross Blizzard, created from a combination of ice and wind elements. Through this magic, Diablo can create a tornado that can freeze an enemy and an area in the blink of an eye.
Once frozen into ice, the enemy's body becomes vulnerable to destruction. Diablo first demonstrated this ability when he faced Gewalt, who was hunting Lumachina in a forest.
10. Flare Burst
Diablo essentially possesses a magic called Explosion, which produces a massive explosion. However, Diablo also possesses a much more powerful magic spell called Flare Burst.
Diablo demonstrated this magic when he fought Varakness. This magic takes the form of a burst of intense heat and massive flames. Those who are weak are instantly burned to ashes when hit by this attack.
9. Absolute Zero
Diablo's next most powerful magic is Absolute Zero. This magic allows Diablo to freeze his target through physical contact. Once the target is frozen, Diablo will shatter it into pieces.
Despite its powerful attack power, Absolute Zero still has limitations. The requirement for activating this magic is that Diablo must directly touch the target. Without physical contact, this magic is useless.
8. Hercules Lance
The Hercules Lance takes the form of a giant lightning spear capable of devastating damage. Furthermore, Diablo needs time to cast this magic in combat.
Diablo first used this magic when he faced the Large Black Dragon. The Hercules Lance managed to pierce the Large Black Dragon's body and weaken its defenses. However, this magic wasn't enough to kill it.
7. Rock Cannon
Diablo's next strongest magic is Rock Cannon, which is based on the earth element. With this magic, Diablo can drop a giant boulder from the sky onto his target enemy.
Diablo briefly demonstrated this magic when he fought Grun, who was capable of summoning terrifying monsters. The magic's destructive power was proven to be able to destroy powerful monsters in the blink of an eye.
6. Naraku
Naraku is a magic spell that takes the form of a small black hole. This black hole can draw in nearby enemies and trap them in a dimension of darkness.
This magic's effectiveness is described as extremely high, with a 5% chance of failure. This magic was first demonstrated by Diablo when he punished Gregor, who had caused a riot in the city.
5. Matoi Izuna
Diablo's next most powerful magic is Matoi Izuna. When using this magic, Diablo releases a kamaitachi lightning bolt and fires it at the enemy. The lightning then gradually damages the opponent's body from within.
Ultimately, a massive pillar of lightning erupts, instantly destroying the opponent's body. Diablo used this magic to defeat the Hydra monster summoned by Keera L. Greenwood.
4. Gravity Abyss
Gravity Abyss is a complex magic consisting of two high-level magic techniques: Dark Arc Seek and Black Hole Arrow. This magic works much like a black hole, sucking in enemies with full force.
Dibalo once used this magic to defeat a monster called the Sand Whale. However, this attack wasn't enough to defeat it. Diablo needed help from Batutta and Luminitus.
3. White Nova
White Nova is one of Diablo's most powerful spells. When using this magic, Diablo releases a white fireball the size of a ping-pong ball from the tip of his staff.
The ball then falls to the ground, producing a devastating attack that decimates a wide area. Diablo first used this technique to annihilate a large army of demons attempting to attack the city of Faltra.
2. Apocalypse Abyss
Apocalypse Abyss is a complex magic based on the four classical elements: earth, fire, water, and wind. This magic is extremely powerful and suitable for combat in confined spaces.
Apocalypse Abyss was first used by Diablo when Krebsklum was rampaging and threatening the city. This magic proved effective in weakening Krebsklum. However, it requires considerable preparation and is very draining on stamina.
1. Annihilation Sphere
In this author's opinion, Annihilation Sphere is Diablo's most powerful and destructive magic technique. When using this magic, Diablo first creates two spears: the Shining Lance and the Darkness Lance.
Diablo then fires the two spears directly at the target. Afterward, the target's body is enveloped in black magical energy and destroyed in the blink of an eye. Diablo used this magic to defeat Vishos and the god of destruction Europa.
