Strongest Ben 10 Aliens

The Top Ten

1 Alien X

Alien X is the Codon Stream's DNA sample of a Celestialsapien from the Forge of Creation. Celestialsapiens are infinitely powerful, capable of controlling both reality and space/time to their will. Their reality warping is so powerful, that their mere thoughts become reality. However, a Celestialsapien cannot do anything unless at least 2 out of 3 or all of its personalities agree on it. They have spent eons debating before using any of their powers (Alien X was so backlogged by debates that it was still undecided on whether it should save the dinosaurs from extinction).
Ben acknowledges Alien X as his strongest and most powerful alien; however, he cannot afford the cost that comes with becoming the alien.

Definitely Alien X is a strong and powerful selestialsapien that can change the fabric of space himself. But with so much power has a bad part, he has two stubborn other sides of Alien X's mind. But they were arrested which gave Ben Tennyson the ability to control Alien X willfully and without wait. But Ben can't be to grateful of alien x being able to do anything because if Albedo was able to get Alien X's DNA from the omnitrix, He would be unstoppable. So Alien X by strength, skill, speed, reflexes, and brains would give him the advantage anytime but alien x is still too risky to use most of the time

Why do people think that Ultimate Ben is more powerful than Alien X? If Alien X just thinks of something, it will become true. I hope nobody forgot the fact that Ben has mastered Alien X and can use it just like he wants to. Here is an accurate list of most powerful Ben 10 aliens:

1: Alien X (Two words: Over-powered)
2: Clockwork (His Chronosapien time bomb is amazing)
3: Waybig (This guy can destroy planets)
4: Diamondhead (Can regenerate, and is indestructible)
5: Chromastone (Absorbing any blast you shoot at him and he can shoot it back? Awesome! )
6: Ghostfreak (He can possess people)
7: Atomix (Tell me, since when did nuclear power go down in popularity? )
8: Upgrade (Technology control is amazing)
9: Big Chill (Freezing matter? Breathing out air that is 0 degrees Kelvin? Stupefying! )
10: Goop (Getting atomized cannot even scar this guy)

People say Ultimate Ben because he can transform into any alien by saying the alien's name, but that still means he must have an ultimate transformation. Alien X has infinite power. So tell me, what is infinity plus the power levels of the other aliens? INFINITY! Alien X is just as powerful as Ultimate Ben, but Ultimate Ben has to say his name, so he can easily be killed before he transforms. Alien X can't be killed. Alien X survived the UNIVERSE IMPLODING, THEN RECREATED THE EXACT UNIVERSE. The best Ultimate Ben can do is a tie.

2 Ultimate Way Big

Ok so I've been doing some research on Unlimited Waybig and Alien X.
Although Alien X has more powers and is a little bit stronger then Unlimited Waybig,. Unlimited waybig is easyer to access and easyer to control. Also, Unlimited Waybig has a biger time limit. He will stay Unlimited Waybig longer then alien X staying alien X. Here's something you might not now. Alien X intorfers with Ben's thoughts and feelings, witch could cause to bad choices and decisions. Once in awhile alein X can erase membery from him perminitly, even in human form. I think that unlimited Waybig is cooler then alien X.

P.S: If we were comparing raw power, Alien X would win.

Ultimate way big is the strongest alien and he will be in the first number. Yes he will because ultimate way big defeated atomix and alien x. Its true he will in the fist.

Way Big is a colossal humanoid creature with a large fin on his head, which is black at the front and red at the bottom.

It is as large and powerful to destroy any alien except alien X and his sonic power is the best.

3 Ultimate Ben

This is so damn stupid ultimate ben the power of alien X and every other alien! So how are way big, ultimate way big, and alien X better than ultimate ben!? Ultimate ben is the best! People can go on and on but this guy is gonna come out on top. For the last time, ultimate ben is the best

Ultimate Ben can use Alien X's powers in this form without turning into Alien X. Therefore, all the powers of Alien X without the problem of multiple personalities.

I think all aliens in the list qre good but again the thing is ultimate ben can change into anything without waisting a second.

He should be on top those are all is aliens at the top he can even be better than them

4 Ultimate Humungousaur

Way Big was up against 5 ultimate aliens and he easily tossed them away like nothing. Way big only lost because he was caught off guard. 1 on 1, he will easily beat Ultimate humungusaur. Also, atomix >> Ultimate humungusaur. He should be 5th place.

At the peak of his power he will beat the thing, hulk, and even the juggernaut.

No he can't are raving mad hulk is strong like thor and thor in old days was invincible

Ultimate Humungasor has lost more battles than any other Ultimate, so putting him so far up is unrealistic.

He is very strong. He can turn his arms into firing missiles. He is the best

5 Atomix

Atomix is explicitly noted by Derick J. Wyatt to be Ben's second most powerful form after the omnipotent Alien X. The surface of his power hasn't even been scratched, and considering that he has the power to make tiny, stable green stars with minimal effort, that's saying something.

Its true that Alien X is the most powerful, but what's the point if you can't even use that power? Atomix defeated Ultimate Albedo, even when he used 2 Ultimate Aliens! Now who can beat that?

Dudes. Derrick J Wyatt has stated that Alien X is no. 1. Atomix is no. 2. So there is no need for discussion. Ultimate ben doesn't exist. Ultimate way big is gone
And derrick J Wyatt stated that way big is ben's 6th strongest alien.

I think he can also defeat alien x and way big he should be number one I like him and alien x second

6 Waybig

I think Waybig is the strongest because he is like 100 feet tall. He could might even take down 200 Dna Aliens. He can destroy Jet Ray. Waybig can scramble him up. And he will be mashed. He might even take down Humongasaur to be honested.

Way big is the strongest and most powerful alien he can cause earth quakes just by punching he apered in secrets of the omnitrix. I love him so much he's the
Best alien ever

Way big can defeat alien x beause last time I saw a video of way big deafeating alien X. I knowthat you have not seen it. The video was very difficult to see,. It was on YouTube please see it

Way big threw vilgax into space and toppled a giant vilgax

7 Diamondhead

Diamondhead defeat feedback I see in the you tube. Diamond head body is hard. I love diamond head because he is stronger.diamond head defeat malware, vilgax and kevin.I think diamondhead would be 6. Diamond head can also defeat swampfire and heatblast. Now you see what I right. This is true. You have to go Google and search it. Wow I love it my diamond head.

Diamondhead would be be one of the strongest because Ben's had most experience with him, as he practiced as Diamondhead the most. He beat Vilgax really easliy with him

He was the only one other than way big to beat vilgax, he has amazing strength, diamond hard skin, and controls diamonds! He's hard to stop!
-18hunt

Diamondhead is awesome he is invincible (almost) and he can shoot diamonds! (the diamonds should rip through a person's skull).

8 Ultimate Echo Echo

Remember that ultimate echo echo's sonic doom attack almost killed ultimate kevin after just some seconds. Sonic Doom can easily kill weaker enemies and humans.

He is 2nd best ultimate after ultimate humungosaur

He could have killed ultimate Kevin when no other alien could even get close. Sure, Alien X can control the universe, but what’s the point if the power is impossible to use

What isn't feedback on this list? He's by far one of the most powerful transformations and should definitely be on the top 10. Ultimate echo echo on the list but he isn't? Come on people!

He can survived powerful nuclear blast, able to travel as fast as jetray and manipulate sounds that no villians can withstand

9 Eon

Eon is awesome! He can travel through time! He can destroy every time line and can rebuild them in his image!

Eon even vanished way big and swampfire so he should be no 4

He is villain! Dude

I hate him
He is really bad
He vanish swampfires and waybig

10 Upgrade

Honestly, I think upgrade should be number 8, Upgrade is one of the best aliens to get ben out of sticky situautions or trouble. Upgrade can control almost everything that is metal or a object that moves. He has a beam that blasts out of his head that can melt anything, hotter than lava.

When there's ben 10 and generator rex crossing episode, ben upgrades rex's building machines! And that's so awesome!

If he can morph into anything that makes him insanely powerful

Absoultely epic can upgrade anything including your face

The Contenders

11 Rath

Rath may not be one of the strongest aliens but he is still very strong and tough.
Someone wrote "Rath sucks", well, he's a complete MORON for having written that.

Rath can rival Fourarms and overpower him with brute force (fact from the official page of one of Ben 10 magazines) and while not being the smartest alien out there, he's more durable, faster and more agile and will never give up, he's a fighting pro!
Ben should have used him way MORE often!

I think Rath has a great potential considering the fact that that he has a lot of serious advantages as a fighter let alone inhuman strength.

Lemme tell ya something! Rath is the strongest alien and don't try to argue because you'll just make him ANGRY!

12 Clockwork

Just saying Clockwork is unreasonably downplayed. This alien is somewhat durable, but it can apparently be damaged by Captain Nemesis's arm cannon, which isn't that strong. Also, damage taken will be permanent. Also, it took 2 Clockworks to take out Eon, where one Alien X could probably decimate Eon.

He is awesome he can stop time I mean he's basicly invincible he could be ben 1 and just have clock work clok work is much better than alien x

Clockwork can do everything about time. He can freeze time, accelerate time and slowdown time, he could do this by using his time ray or b not. Clockwork could travel throughout space and time, and he knows all anout time.

Clockwork should be number one when he's in a fight he can just slow down time and beat everyone up

13 Feedback

Boy I feedback is wow can you just believe that he defeated malware so easily after unlocking him. Feedback is my favorite alien should be first or second

My best alien FEEDBACK! Do you know how he kicks his opponents on the face dude he's awesome! But do you know before he was bens favorite alien

He connects with Ben the most and beat a giant malware who even way big couldn't defeat

He can turn anything into electricity then kick everyone's ass

14 Chromastone

Chromastone is even power full than alien x. Due to his unbreakable able crystal body he can even absorb alien x. Have ability to face time bomb because he is a crystal and crystal do not have age while alien x cannot do this

Yes time does not effect crystal. Hence he is even more powerful than alien x. Also his energy is more than 10^30.His specie is also least known. This was told by tetrad and Ben. He is also saviour of his planet. Has force field so no one can attack him even alien x is poor in front of chromastone.

Chromastone is so powerful because he can do shields that can stop attacks and he can absorb attacks. He can also shoot pure energy blasts. I know he runs out of energy butt if he can find enough energy like all the energy of an anidite or diagon or the most powerful substance in the universe

Chromastone can absorb energy, fire lasers, and is practically unkillable. He brought BEN BACK TO LIFE! I just hate it when he gets destroyed.

15 Benvicktor

Ben victor has an electric body that is a good advantage for his body

He is avery strong and full of electricity

Good but look crazy

That is so not true

16 Humongausaur

Humongasaur is strong enough to hold way big
The strongest at ultimate

He's getting bigger and stronger

He is strong enough to beat alien x

He's. An assassins he destroyed armodrillo in an episode

17 Swampfire

Super underrated character like seriously he can't be harmed he grows rapidly his heat is stronger that heatblasts he can trap anyone in millions of vines he can grow in size if he was crushed burned lazered shot sliced or anything else he would shake it off no problem he also has incredible strength.

Swampfire his invinsible to bullets because they pass through hi. If humangosaur tries to crush him, he can come out from another plant. His firepower is stronger than heat last since he can use his methane as a conducter

Swampfire is the 3st alien because the swampfire has more power and he is an plant

Am I the only one who thinks heat bleast is absent in this list

18 Big Chill

Ivisiblity, flight, eats metal, freez attacks close and ranged.
One of the few alien that can survive out in space.

He can change the temperature of a place and is invisible

Muscle, Invisible, Icy, Fly, can eat metal and tear them and look cool anway

He is frikin awesome he is a frozen ghost dude and he is really strong

19 Goop

You know, goop can actually be better than swampfire. I mean, plants can be harmed by acid, so, goodbye swampfire or any other methanosian when in contact with goop.He also has shape- shifting abilities, can shoot, spray, or hose his slime that can be acidic or adhesive, can fit through anything, and, theoretically, can self- duplicate or grow into a large goop. Think about it, with his regeneration, his leftover slime can be sentient because that leftover slime is still ben, and the omnitrix might make another anti- gravity disc for the leftover blob. But that's just a theory, AN ALIEN THEORY, and no, I'm not matpat, I just stole his line.

Goop is the best alien ever. I mean seriously he is made of acid and goo he is the BEST! You can not damage him! PERIOD

Goop attack by just shooting slime to vilgax which he should not be in this list because he sucksss! His fighting skill sucks

It is the best alien it should be first the most powerful alien who produces dangerous acid su

20 Atomic-X

Atomic-X should be highernas its ability to use toxic waste is good, it can do ANYTHING and lets face it, NO ARGUING! In the end its just wayto op to be 20th

I think he should be number 1 because Atomic-X once defeated Vilgax

He is good and should be higher on the list below possibly alien x.

He is awesome half made of the strongest alien in universe

21 Vilgax Vilgax is a fictional character and one of the main antagonists of the American animated TV series and media franchise Ben 10 created by Man of Action Studios and produced by Cartoon Network Studios.

A powerful villain which if it weren't for articguana he would have defeated ben 10 and ben 10,000

Even if he was an alien he can't find his place in the top 30

He is very foolish and could not beat Ben 10 at any limit

I hate octups

22 Heatblast

I love Heatblast, because he's super powerful. Also, my favorite element is fire.

He made a fire tornado, and can reach the temperatures of the sun!

Heatblast has been my favorite alien since I was three years old.

He beat vilgax

23 Four Arm

Well four arms is faster strong because he is faster than humunousaur and smarter then rath

Because he was chosen for a feat of strength when competing.

Whenever ben needs to lift, crush, wrestle with someone he will use fourarms

Very strong alien but also overrated as hell.

24 Gravattack

Gravattack can control gravity to manipulate the weight and motion of objects, allowing him to suspend and levitate targets in the air, send them flying back or fourth, or slam them down to the ground with hand gestures. His control over gravity allows him to change its direction, allowing him to telekinetically send targets flying upwards or across the air as if they were falling. He can also place objects into an orbital track, causes them to fly in circles at various speeds. When using his powers, he emits an aura of hazy energy. He can even form this energy into walls, barriers and domes.

Gravattack could move a planet and a sun, I'm pretty sure he'll soon be able to move a solar system

He could just move his hand and defeat any villain and should be number 3

He is so cool he can lift up alien x or crush him with gravity he is probbily my favorite ben 10 character

25 Evil Way Big

Super intelligence, super strength, enhanced durability and cosmic rays I say no more
