Oppo (オッポ, Oppo^?) was one of the 11th Division Combat Executives of the Great Demon King Army and served under the 11th Demon Lord, Jachi.

Appearance

Oppo had a large, heavy body type, a round hairless spiky head with no eyes, and a wide mouth with spiky teeth. He also had a long, thick tail with a mace-like tip. He wore simple spiked armor that protected his shoulders, and a type of underpants. Upon transformation, Oppo's body appearance slims down and becomes visibly more muscular, and the mace-like tip of his tail transforms into another huge mouth with sharp teeth with his tail gaining a lot of mass as well, indicating that his heavy body mass is transferred to his tail.

Personality

Not much is known about his personality. Oppo didn't seem to communicate like his fellow 11th Division Combat Executives, and his only words were "Kill enemy", indicating that his mind is either very simple or he couldn't speak as well as the others. Oppo seemed to be another confident and proud combat executive of the demon army, just doing what he was ordered to do.

Plot

Demons vs Aliens Arc

Oppo arrives on the battlefield with Bikkuk and Shinso as Kiva used his Demon-Flute.^[1] Oppo joins in the fight against one of the Madalans, Galua, with his fellow demon combat executives, but the alien is too powerful for them. The human mages then suddenly give their mana to the demons so they can quickly recover from fatal injuries, allowing the demons to continue fighting the alien.^[2]

When the Madalans decide to stop wasting their energy on them, Galua decides to call in their massive spaceship to decimate the land. Everyone is shocked to see the ship in the sky. They are then briefly saved by a mega kaiju, Daikokuzan, who destroys the ship before their eyes, surprising even the aliens.^[3]

Eventually, when the humans manage to escape from the battlefield, the demons stop receiving mana and the aliens decide to kill the executives, causing even Oppo to lose his life.^[4]

Abilities

As a combat executive of the Demon Army, Oppo is a strong warrior likely on-par with Kiva. However, against the Madalans, Oppo was utterly helpless. Even with the help of three combat executives, he was unable to defeat merely a single Madalan.^[5]

Physical Abilities

• Superhuman Strength: Being a demon executive, Oppo has proven to be a very strong demon, capable of hitting even a madalan to the ground.
• Superhuman Speed: Oppo has shown to keep up with the other demons while fighting Galua.
• Powerful Regeneration: As a demon, Oppo possesses an incredibly powerful healing factor. Should he sustain a lethal wound and find his own mana reserves insufficient for healing, he will require an outside source to bestow mana upon him, which helps to enable his fast recovery.
• Transformation: Like his fellow demon executives, Oppo can transform himself into a larger and more powerful demon by yelling "Burst!". This increases his strength and abilities.
• Body Control: Oppo is able to control his tail like a weapon, extending it when he needs to and using it to attack.

Magical Abilities

• Flight: As a demon, Oppo can fly without wings by using magic during his confrontation with Galua.

Techniques

• Burst: Oppo unleashes his full power, gaining an immense boost to his abilities and undergoing a transformation in appearance.^[6]
• Quartet of Deadly Evil: A formidable assault technique where the 11th Division's Combat Executives combine their power into one overwhelming blast. This attack is known for its incredible strength and extensive reach, capable of causing collateral damage to friend and foe alike due to its expansive area of effect.^[7]
