Aggregor

There are plenty of interesting villains in the Ben 10 series but forget about Zs'skayr. Forget about Vilgax, Darkstar, the Highbreed. None of them compare to Aggregor who is by far the most dangerous villain in the series. Though you kind of have to be when you have the ability to absorb anything just by touching it. Yes Aggregor was an Osmosian just like Kevin and a pretty damn good one as well.

Background

Not much is known about Aggregor. All that is really known is that he wanted to obtain unlimited power. To do this Aggregor kidnapped and absorbed the powers of five aliens before going after 'The Ultimate Prize'.

Powers and Abilities

Being an Osmosian, Aggregor has the ability to absorb anything he touches. Though unlike Kevin or his father Devin, when Aggregor absorbs something there is nothing left.

Equipment

Aggregor's Staff

Aggregor's staff sends out red bolts of electricity. These bolts of electricity can be used for the standard method of electrocution but they can also be used to telekinetically move things.

As revealed in Fused this weapon was specifically designed to deal with electrical manipulative species which is why he was able to defeat Brainstorm, AmpFibian and Ra'ad so easily. In fact according to Word of God this staff was the main factor in his victory in Fused as if Ben had selected a  non-electrical based alien he would have been able to defeat Aggregor (according to Word of God). With this staff he was also able to repel Gwen's mana projectiles and defeat Kevin (who absorbs energy such as electricity).

Weaknesses

Like all Osmosians, Aggregor can only use absorbed powers at 10% efficiency. Though there is a way around it: if Aggregor can turn his victims into pure energy he can use the absorbed powers at maximum efficiency.

Aggregor depended heavily on his staff for combat.

Feats

• Captured the 5 Andromeda Aliens likely in their home territory.
• Captured the 5 Andromeda Aliens again on Earth
• Defeated Kevin, Gwen and AmpFibian
• Defeated Ra'ad
• Survived a garage size explosion (and unlike Vilgax he did not have to take time off to recover)
• Temporarily created a rift in space-time
• Absorbed the Andromeda Aliens to become Ultimate Aggregor.
• Outsmarted the Plumbers twice.

Ultimate Aggregor

After absorbing the 5 Andromeda Aliens, Aggregor became much more powerful.  All he had to do to achieve this form was gather the five andromeda aliens and create a rip in space-time putting all of reality at risk because according to Paradox "reality is already paper thin" there.

Powers and Abilities

Aggregor has the abilities of all 5 Andromeda aliens. As such he has complete invulnerability as demonstrated when he was able to easily tank being thrown through a building and then having that same building thrown at him causing him to go through more buildings (Its better explained in the video).

Aggregor also has selective mana immunity which he received from Galapagus. This allows him to not be harmed from any magical attacks and easily break through mana barriers.

Aggregor can also shoot radioactive lasers from his eyes and also has a degree of electrokinesis. Just one of his electrical attacks was enough to damage Max's entire nervous system.

On top of that Aggregor also has Andreas' strength and was easily able to punch Humungousaur so hard that it created a shockwave strong enough to wipe out some nearby buildings.

In Where the Magic Happens just one of Aggregor's lightning bolts was enough to cause this giant rock to fall over (Note it was vertical before he fired the lightning bolt).

Despite having an increase in power Aggregor has not lost his cunning intellect. He was able to easily cause Ben's Team to do most of the work for him in retrieving pieces of the Map of Infinity in both Map of Infinity and Where the Magic Happens. Both times he got away with a piece of the Map of Infinity while Ben's Team got nothing.

In Perplexahedron Aggregor was able to create a bubble shield to block dozens of missiles. This same bubble shield was able to withstand a high intensity laser.

In the same episode Aggregor was able to destroy a hydraulic press using only his eye beams. Aggregor then defeated Gwen with remarkable ease and he wasn't even trying.

Aggregor did fail to get to the last piece of the map first but Ben's Chronic Hero Syndrome (though if you ask me Aggregor would've gotten it eventually) allowed him another chance by fighting Cannonbolt. He's able to get Ultimate Cannonbolt to drop the final piece and retreats.

Unfortunately Aggregor is finally defeated in The Forge of Creation. Using the Map of Infinity he was able to reach the Forge of Creation which resides outside of the universe/multiverse. He fights Ben's Team and manages to defeat them again even when he had to go up against a younger Ben 10 as well as Ultimate Swampfire. He would've gotten the ultimate prize (a baby celestialsapien) but Kevin absorbs the Ultimatrix gaining all the abilities of Ben's unlocked aliens and stops him. Kevin then proceeds to absorb Aggregor's powers as well.

Feats

• Obtained all four pieces of the Map of Infinity
• Outsmarted Ben's Team twice
• Fought Ultimate Cannonbolt
• 'Defeated' Adwaita
• Defeated Ben's Team
• Defeated 2 Ben 10's at once
• Has never been defeated by Ben and was only defeated by Kevin who had absorbed the powers of all of Ben's unlocked aliens.
