Garmadon's powers and abilities
Spinjitzu: Like his brother, Master Wu, Garmadon has the ability to perform Spinjitzu, with his version channeling the power of Destruction instead of Creation.
Forbidden Spinjitzu: Using Forbidden Spinjitzu, his strength increases and he uses energy waves much more.
Catjitzu: Using a special form of Spinjitzu, invented by Nineko, Garmadon can walk on ropes, jump high with the help of Spinjitzu tornado and jump down in the same way.
Destruction: Garmadon has the ability to control the elemental essence of Destruction. He is able to create Destruction daggers to help him in combat, and he is able to gain more power by battling opponents. After being bitten by the Great Devourer, his power became unbalanced. After being purified of evil after the Overlord's defeat, Garmadon's Destruction returned to balance. After being resurrected by the Oni Masks, he uses Destruction in combat for the first time, manifesting it as purple energy, similar to when he was possessed by the Overlord (not to be confused with Darkness), in the form of blasts, shields and strong explosions. He can also use Destruction to telekinetically choke and even tear apart others from certain distances, as he did with Mr. E, as well as enhance his strength to superhuman levels, which makes him able to easily break through brick walls. He was even powerful enough to blast both his son, his brother, and Firstbourne of the top of Borg Tower greatly weakening all three of them.
Colossus: Using his full power, he was able to use the environment to create an enormous Colossus. He controlled the being with his Destruction element, and created by his dormant control over Creation.
Oni Form: Due to being part-Oni, Garmadon can enhance his strength and other capabilities whilst using Destruction and channeling his anger, making himself turn into an Oni as a result, similar to an Elemental Master user in their Dragon Form. However, if weakened, he would revert back to normal.
Limb Changing: In Christofern, Garmadon was shown to be able to get rid of his two extra arms and grow them back at will (though its possible that his two extra arms were associated with his Oni Form).
Creation: Despite Destruction being his primary element, Garmadon is part Dragon and could access the power of Creation after unlocking his true potential, even though he is mostly Oni in form.
Life bestowing: Garmadon was able to give life to an inanimate collection of rocks to create the Colossus.
Shadows: In his first appearance, Lord Garmadon was able to summon and duplicate shadows, dark entities able to harm physical beings while the latter could not do the same. Similarly, during his stay in the Underworld, he had the ability to use his powers to create a shadow duplicate of himself in order to interact with Ninjago to some extent.
Weapon Summoning: Garmadon can summon weapons from a distance or from thin air. This was shown in "Once Bitten, Twice Shy," where he summoned 4 weapons (a staff, a double bladed dagger, a staff with shurikins, and a scythe) from a distance. He later summoned 4 swords by pulling them out from his back in "The Royal Blacksmiths." In his current form, he can create Destructive daggers, which he used to fight Lloyd and Wu at the top of Borg Tower.
Wielding the Golden Weapons: During his time in the Realm of Madness, he gained the power of doing what was seemingly impossible for him to achieve: to wield all four Golden Weapons of Spinjitzu at once. In addition to this newfound ability, he gained two extra arms to help him hold each weapon more easily—though this new power still left him feeling weak upon using the Mega Weapon. Upon being purified after the Overlord's defeat, Garmadon lost his extra pair of arms, and therefore, the power to wield all four Golden Weapons. It is unknown if he could wield the four Golden Weapons after his rebirth.
Skilled Combat: Garmadon is a skilled fighter, being proficient in martial arts and the use of many different weapons. Initially, after being cured, he repressed his power by refusing to fight, but he eventually returned to being an active combatant in order to save his son. He is also skilled in swordsmanship as he often wields two identical katanas and later four after he gained 4 arms. Even powerless, while they were caught off-guard, he still outmatched all of the ninja and later several Oni with only one sword. During his battle with the Time Twins, Garmadon, unlike Wu gained the upper hand while fighting each of the twins.
Fishing: Garmadon is very good at fishing and has often been with his father, brother, or both to fish when he was a child. He can also swim, as he and his brother Wu often went swimming in the lake.
