Most Powerful Bakugan Ever

Darkus Alpha Percival
Alpha Percival evolved from Midnight Percival. He gained a cape that allows him to hover in the air and swoop down to attack his prey. He also wields a double-ended sword that can slice at multiple attackers at once. Additional spikes cover his legs and chest to make him an even more fearsome foe.

Subterra Mega Brontes
Mega Brontes is the newer version of Brontes, and is twice the size of the orginal. With his new metal-plated armor he can defend multiple blows when attacked, and his clawed hands can squeeze a battler like a vice. Besides being very strong, Mega Brontes is one of the fastest Bakugan balls, making him hard to capture.

Haos Mega Brontes
This is the version of Mega Brontes with the Haos attribute. He is equally as powerful as Subterra Mega Brontes with a G-Power rating of 720G. He can join forces with the Trap Dynamo to form Dynamo Brontes. Mega Brontes was first seen in the animated series when Volt and Lync battled Ace and Shun. He made another appearance in episode 14 when Marucho and Elfin face Volt and his Brontes.

Ventus Percival
Percival is a ruthless warlord who uses his cape to disappear from sight. His means of attack are plasma bullets that shoot out of his three mouths. One of his signature attacks involves creating a black tornado with purple sparks to damage opponents. There are two dragon head guards on his wrist to serve as gauntlets, and his body is protected with steel-plated armor. His horns are the strongest of all as they are indestructible.

Haos Mega Nemus
Mega Nemus looks similar to Nemus except he has an additional layer of armor that protects him from elemental attacks. Two discs shoots from his staff when he attacks. His crown has four stones embedded in it that even knocks down even the most powerful enemies.

Subterra Dual Preyas
Preyas II is a clownish character that often uses humor to avoid fighting. Despite this he is very strong when he does battle with foes. He has the ability to change attributes during battle. It is preferable to battles with the Aquos attribute as he is at home creating strong water ball attacks.

In the animated show when Drago was fighting Maxus Helios, Drago had to give in and turn into a Mechanical Bakugan. When Shun, Marucho, and Mira were trying to free the five other Bakugan they destroyed the Dimension Controller and caused the fight to end, but Drago still battled Helios without the Mechanical Bakugan.
