Strongest Ben 10 Aliens

The Top Ten

1 Alien X

Alien x can do anything. He can fix every thing. His power is unbelievable. He is the strongest of al

Ben is afraid that alien x may be too powerful to control. And only uses in dire situations

alien x has extreme power which allows hin to destroy any thing in his way, but because of this immense strenght he freezes for a long time

Alien x is the best!

2 Ultimate Way Big

Ultimate way big is basically tripled the size of way big and all the abilities are better.

Ultimate way big is the most powerful of all because he has the ability to fly and is three times bigger than the old form and can shoot from his arm instead of crossing it

He is big enough to throw waybig

Ultimate way big is the ben 10 strongest and largest alien

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

He is every alien! He should be number 1!

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

He is everything

4 Ultimate Humungousaur

Best ben 10 alien and my favourite

One ultimate humunasour was able to take on hundreds if not thousands of Regular humunasours

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

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

V 22 Comments
5 Atomix

Atomix can destroy anything.

Atimix is most powerful as he overpowered negative ultimate aliens

It's powerful than ultimate way big

I think it should be number 2 cause atomic has literally has only lost one fight and Ben usually reframed from this form due to its destructive nature

V 40 Comments
6 Waybig

Way big threw vilgax into space and toppled a giant vilgax

way big can cause an earth quake just by punching.

way big is the biggest alien

he is the biggest alien that use in strong aliens like huge vilgax

V 25 Comments
7 Diamondhead

He can reflect all energy attacks and can go toe to toe with strongest aliens.

I feel he should be much higher as he can regenerate making him invincible

Diamond Head is the best alien in ben 10

Diamondhead is awesome

V 21 Comments
8 Ultimate Echo Echo

Defeated ultimate kevin levin, superpowerful

Very easily defeated Kevin in ultimate episode when kevin absorbs ultimatrix

I literally have never seen ben lose a fight with this alien

Ultimate Echo Echo can knock almost anything out easily

V 17 Comments
9 Eon

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

He is villain! Dude

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

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

V 1 Comment
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.

I think heat blast is better

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

Upgrade is aswame upgrade ca do eney thing

The Contenders

11 Rath

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.

I believe Rath is physically the strongest alien. Not to mention he's my #1 favorite alien lol

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

V 15 Comments
12 Clockwork

I thought his name was clockback for the longest time

He can't destroy alien-x as alien-X doesn't need time and it won't matter if time is stopped or not Alien-X will never move but even when it is frozen you cannot make a scratch on alien-X

Clockwork can beat ultimate waybig 100 times over. He can stop time and use literally and resource at hand!

Clockwork should be much higher

13 Feedback

He's Awesome! He can absorb the Big Bang's Energy.

It is very gethu

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 can turn anything into electricity then kick everyone's ass

V 26 Comments
14 Benvicktor

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

He is avery strong and full of electricity

That is so not true

15 Humongausaur

humongausaur is strong enoung to bench press pick up truck. and his strenght only increase with his size

He's getting bigger and stronger

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

He is the tremendous dinosaur

V 13 Comments
16 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 A POWER ABSORBING, LASER BLOCKING, INVINCIBLE CLONE. did you see how IN THE GAUNTLET he took on every single attack by cash and wasn't harmed at all. He must be made of crystal. All his energy bolts sting the baddies. No matter what attacks him he will survive.

He is awesome he is the original feedback but 10 times better he brought ben back to life and then HE CAN FLY feedback can't do that he is just a cheap remake of chromastone

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 might look a walking compost heap. but he's the one of ben's strongest alien

swarp fire is powerful alien because he never broke

Swampfire is cool in omniverse

V 6 Comments
18 Big Chill

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

He is the best

Big chill can pass through solid matter and drop the temperature of anything he choose to nearly absolute zero

I love how he talk and also I think that big chill could beat up ultimate way big because he can invisible and go through anything

V 5 Comments
19 Goop

there's more to this giant glob of goo than meets the eye. goop is able to change of his body at will

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

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

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

V 8 Comments
20 Atomic-X

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

Atomic-X does not need to negotiate with itself and it has the plasma powers of Atomic, he should be the best seriously

He can do anything he has all the power of bens most powerful aliens and since he's half Atomic he doesn't need to debate

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

V 7 Comments
21 Vilgax 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.

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

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

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

22 Heatblast

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

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

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

He beat vilgax

V 4 Comments
23 Four Arm

The four arms is great alien

Best alien

4 arms, mean double the punch, He could fight any monster and win! The strongest by far.

I love four arms he can kick everyone s butt

V 22 Comments
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

His power is he can end gravity

GRAVITY POWERS, just send the others aliens into space using the power.

25 Evil Way Big

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

26 Fasttrack

He is way better than xlr8

He is the fastest

Xlr8 is faster then fastrack because ben knows more abilities of xlr8 than fastrack...He known xlr8 more t han fastrack.

27 Ultimate Alien X

Alien x is the most power full alien

Shld be 1 cause alien x is waker and where is ultimate swampfire should be in top 3

If alien x went up to vs ultimate ooohh he will be wrecked

How is non ultimate better than ultimate

28 Brainstorm

He is very intelligent and can make electrical storms

He can made storm just by thinking
He is very intelligent
He can open his brain and produce shockvaves

29 Ghostfreak

He can defeat rath as he can get inside rath and defeat rath

He can take over other people and turn completely invisible. He also has telekinetic powers and can survive even when he's just a few bits of dna... How is he 27 should be at least top 15

He can be invisible and go inside everything

He can move through people and can scare his apponents to make them forget what he's doing.

30 Articguana
31 Jetray

the manta-like jetray can move throught air or water at several times the speed of sound

Jet is not that powerful but he is reliable. He can fly and swim at the speed of light and can also survive in the vacuum of space

32 Gwen Tennyson Gwen Tennyson Gwendolyn "Gwen" Tennyson is a deuteragonist of the Ben 10 franchise. She is the human/anodite hybrid Plumber, the paternal first-cousin of Ben Tennyson, and (along with Kevin Levin) a frontline member of his team.

Gwen is not even an alien she sucks

She has the power of magic need I say more

She can use her mana for protection, levitation, flying and picking up things!

Gwen should be number 6

33 Armodrillo

This mechanical animal is able to pass throw rock like we pass throw air and is able to cause earthquakes

Just imagine how much it must hurt to be hit by a fist that can create earthquakes.

34 Ultimate Feedback

He is waaay better than alien X

He is better than regular feedback! Actually he is better than alien x his color and his style he awesome dude! He is one of best alien in Ben 10 history! He sucks attacks two times faster he is even taller then before isn't it awesome

35 Ultimate Rath

Ultimate Rath is OP

How many times do I have to say this,"there is no power greater than omnipotence"meaning to say no alien is more powerful than alien X and that's a fact

He is like a wrestler

Ult rath is the mist powerful alien ben ten ever had because he has no weakness he can defeat alien x very easily

V 1 Comment
36 Ultimate Spidermonkey

What the he is better than feedback and atomix. He should take their place.

What is stronger than eon

They made him weaker then spider monkey

They didn't

37 Professor Paradox

Professor paradox has total control over time, even IF he loses in a fight, he can rewind time over and over again until he wins, yes, I can understand that alien X is better, but I chose paradox because he's like the ultimate version of 'prince of Persia' and I love prince of Persia. I love anything that talks about controlling time and all of that!

He is a meddling time traveler has been seen warning ben and gwen in troublesome times

Hey parradox is the best...

How is Gwen higher in the list than PP? He should be on top next to Alien X

38 NRG

He can melt any thing. And if he puts something knits full head it can swim.

Once he is out that suit he is invinsable

Wait a minute. He should be number 2 strongest alien. I know that atomix is what you think is the second strongest, but when he battles this hothead, HE CAN ABSORB HIS ATTACKS. HE IS NOT JUST GOING TO FILL UP HIS STOMACH, HE CAN INCRESE HIS POWER. ATOMIX CAN'T ABSORB ENERGY, BUT "NRG" CAN, because HE'S "NRG"

He is swaggy

39 Ultimate Invincible Alien X

Alien x is more power ful with his ultimate form he should be no1 instead of simple alien x

He is the can duplicate powers and can make himself more powerful

If he really is invincible then yeah sure he should be the best

If he exists definite

40 Kevin Levin

This guy can absorb anything and redirect it however he wants osmosians are bye far the most dangerous species even an anodite would die if they touched them and they would have all their powers because they are made of energy they can kill any alien if they want, it does not matter how strong they are. Need any more reasons?

Kevin levin should be number 10

He is the strongest
He should be at first
Cause when he absorbs ultimatrix he gets the power of all the aliens
Alien x too!

41 Shocksquatch

Shocksquatch got amazing strength

42 XLR8

He is awesome in defense but very bad in offense

Wow that dude can make a whirlwind with that kind of speed he might even beat usain bolt

A classic character with a faster speed in my opinion.

He can made tornados and walk and 500 km per hour
Very fast
And my favourite

43 S.A.M.
44 Ken 10

The ben 10 of the future

45 Ultimate Chromastone

I've seen Chromastone be strong and everything but I can't wait intill I see Ultimate Chromastone!

He is the strongest alien that ben had he is stronger than alien x he is so power ful

46 Ultimate Swampfire

Ultimate swampfire is the best. Alien x,ultimate waybig,ultimate humoungousour is very good but ultimate swampfire is better than them

Ultimate swampfire is the best. Alien x,ultimate waybig,ultimate humoungousaur is very good but ultimate swampfire is better than him.

Ultimate swampfire is stronger than regular swampfire. he shoould be in 11th place.

47 Ultimate Big Chill

It is very good alien I like it it deserves a chance in to 2

He can freeze anything

48 Ultimate Heatblast

Ultimate Heatblast is more stronger then the original Heatblast.

49 Spidermonkey

resembling an earth monkey, this multi-limbed alien has superhuman agility

50 Ditto

Ditto can turn into as many aliens as he likes

Ditto (a splixon from the earth-like planet halthor) has agility, a sence of humer and cam form an army! Echo echo is just a copy ( plus when echo echo times out he just makes more bens, but ditto will NOT time out unless they are all joined! He has always been my favorite (but before I descovered him it was upgrade, diamond head, then stink fly)
