Zebub contract: Is the sign proving he's the royal family contractor and allows him to use beels demonic energy
- Zebul Spell (ゼブルスペル, Zeburu superu): The spell on his right hand expands and grows, moving up his arm and spreading across his face. The more it expands the more Oga's power grows. First, when he lost control against Kiriya the Zebul spell temporarily extended up his arm, over his trunk and across his face. After his training with Saotome, he's able to recreate that state through drinking the Super Milk, but his Professor warns him that if it goes any further that, he might not be able to become human anymore.
- Zebul Blast (魔王の咆吼, Zeburu burasuto; Literally meaning "Demon Lord's Roar"): Oga punches his opponent and releases a large amount of demonic energy that's strong enough to destroy a building. After his Ankokubutō training Oga can use this attack freely without having to wait for his energy to build up.
- Zebul Emblem (魔王の烙印, Zeburu enburemu; Literally meaning "Demon Lord's Burning Seal"): Oga uses the Zebul Spell to target his opponent, then punches it until the enemy explodes from the massive power build up. Through Super Milk Time he can stand on the emblem in mid-air and use it's explosion to increase his speed. Oga can also attack with more than one emblem at once when used in conjunction with Super Milk Time.
- Zebul Finisher: This is Oga and Beel's ultimate technique where it was first used to defeat Naga, Hecadoth, and Graphel together that involves placing hundreds of Zebul Emblems around the opponent and he proceeds to create a linear chain of Zebul Emblems in front of him that acts as a trigger for an enormous explosion that destroyed the top of a building. It was used when Baby Beel gained complete control over Oga's body from their untrained Super Milk Time. Later on it was used to defeat the fusion of Fuji and Satan where Oga performs in his normal state and has hundreds of Zebul Emblems placed in front in him like a wall that went above even the Earth's atmosphere. Oga then procceds to unleash an enormous energy blast this time that stalemated the Fuji/Satan fusion's final attack before overpowering it by placing numerous King's Crest on humans and demons alike that are aligned to him to absorb their power.
Super milk time: Demonic milk that allows him to fuse with baby beel
Demonic energy blasts: Whilst controlling baby beel's energy he can release it in a powerful blast with his punches
Annihilation energy: When he combines controlled and fused demonic energy within his body to make the must use of his remaining demonic energy
Super Saiyan: When Baby Beel releases his maximum demonic energy and converts it into an electric aura and then amps Oga with it. It gives Oga increased durability, speed, strength, and the ability of flight.
