Notable Attacks/Techniques:

Zakeru: Zeon shoots a powerful bolt of lightning from his hand.

Zakeruga: A concentrated beam of lightning fired from the palm.

Teozakeru: The technique which creates a powerful thunderbolt from Zeon's hand. A powered-up version of Zakeru.

Jauro Zakeruga: Shoots an enormous ring of electricity with many Zakerugas emanating from it.

Barugirudo Zakeruga: Tremendous burst of lightning from above that fries the enemy.

Raajia Zakeru: Creates a shockwave of electricity.

Sorudo Zakeruga: A huge sword with a blade made of lightning is summoned, which Zeon can hold and use as a physical weapon.

Ganreizu Zakeru: A multi-turret gun is summoned, allowing for several small blasts of lightning to be thrown out at the same time.

Reedo Dirasu Zakeruga: Zeon summons a huge circular object with many blades sticking out like a buzzsaw and is controlled by a small lightning bolt like a yo-yo. He is able to manipulate the electric yo-yo through the string to slice and smash through anything.

Jigadirasu Uru Zakeruga: Zeon's strongest spell which summons a massive, winged thunder god. Said entity fires five thunderbolts from the holes/cannons on its body which merge into one tremendous Zakeruga blast.

Unnamed Gigano Spell: In the anime and chapter 77 of the manga, it is revealed that Zeon has a Gigano spell but he stopped Dufaux before he could say it. He never used the spell so its unknown what its name is or what it does. However, as the reason Zeon stopped Dufaux was because he felt the spell was overkill at the time, it hints that the spell is very strong. Since in the manga it's seen that Dufaux only said "Giga...", it is possible that this was an error in spelling or translation of Jigadirasu Uru Zakeruga.

(Note: While the following five spells are only used in video games, Makoto Raiku later confirmed that Zeon does have them in the manga)

Rashirudo: Zeon summons a shield in front. Any projectile that hits it will be reflected, damaging the opponent with a combination of their own attack and lightning energy.

Jikerudo: An energy ball that magnetizes an opponent.

Rauzaruku: A rainbow-colored lightning bolt hits Zeon and temporarily increases his strength and speed. However, no other spells can be used during this time.

Zaguruzemu: A sphere of light that charges anything it strikes with electricity.

Zeo Zakeruga: Zeon fires an electric white dragon from his hand that looks just like Baou Zakeruga.
