2 Ultimate Way Big

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

How is way big higher than ultimate way big ultimate way big can do every thing that way big can do plus more can way big fly no see and alien x is like number 20 you need to make sariina and belakus agree first wich is like the hardest thing in the world to do

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!

4 Ultimate Humungousaur

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

He is the best he can even defeat way big he should be the third

The power

5 Atomix

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?

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.

Awesome awesome awesome. TELL ME ONE GOOD REASON WHY ATOMIX ISN'T AWESOME, HE IS THE BEST. NUCLEAR ENERGY IS BETTER THAN BEING INVINCIBLE HE COULD SHRED EVERY LAST ATOM IN OMNIVERSE. THERE IS NO ONE BETTER THAN HIM, JUST WATCH THE VIDEOS. HE IS STRONG AS WELL, IN FOR A FEW BRAINS MORE, HE KICKED HIS TEAM INTO THE SKY WITH ONE LEG. Atomix is epic

BOIII ITS ALIEN X WHO IS CURRENTLY NUBER ONE PLUS THE POWER OF ANOTHER ALIEN BISHHH U TRY AND MATCH THAT

7 Ultimate Echo Echo

Ultimate Echo Echo can knock almost anything out easily

Ultimate echo echo sound wave is op making his enemies fall unconscious or even worse deserves to me in the top five or more

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

Ultimate humongosaur
Diamond head
Big chil
Swampfire

8 Diamondhead

Diamondhead is made of hard crystals and can morph his arms into effective rudimentary weapons.

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 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

Diamondhead is awesome

V 18 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

Eon was AWESOME

Too bad they had had to ruin him him in Ben 10 Race against time 😡

Yeah I'm still mad about that

V 1 Comment
10 Upgrade

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

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.

If he can morph into anything that makes him insanely powerful

Upgrade is aswame upgrade ca do eney thing

The Contenders

11 Rath

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

Rath is amazing if any alien tried battle him rath would win by a mile.

Rath is a angry aliens and that is my favourite alien and his claws, his claws are so power full

Lemme tell ya something alienx you want a piece of rath you will gett it

V 12 Comments
12 Clockwork

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 should be much higher

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

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

13 Feedback

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 and take energy away and dish it out 10 times stronger

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

V 22 Comments
14 Humongausaur

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

16 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

He looks so awesome. It is like he is a powerful chrome stone.

CHROMASTONE can absorb most of the radiation coming on him.
And he is also physically very powerful so can easily fight of any alien.
HE SHOULD BE THE SECOND MOST POWERFUL ALIEN AS HE CAN EASILY DEFEAT ATOMIX
CHROMASTONE HAS THE STONE OF PETROPIA WHICH ENABLES HIM TO ABSORB UNLIMITED ENERGY AND CAN EASILY ABSORB ALL THE ENERGY OF ATOMIX AND THEN REPEL IT BACK TO HIM,
DESTROYING HIM INTO PIECES
AND SO CHROMASTONE IS THE MOST POWERFUL PRACTCAL ALIEN WHICH CAN DEFEAT EVEN VILGAX AND SO SHOULD BE THE SECOND MOST POWERFUL ALIEN OF BEN'S OMNITRIX

17 Swampfire

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

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.

18 Big Chill

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

He can change the temperature of a place and is invisible

I make a correction there.actually below 0 degrees,like minus 100 degrees!

V 3 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 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

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

V 8 Comments
20 Atomic-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

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

V 6 Comments
21 Four Arm

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

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

He has FOUR ARMS! 1

22 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.

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

23 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’s my favorite and one of the most appeared alien and think he’s funny and cool

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

How is non ultimate better than ultimate

It should be number 1

He is the 5th best

He is the my best 👽 alien because he do all things he

V 3 Comments
28 Ghostfreak

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 defeat rath as he can get inside rath and defeat rath

He can be invisible and go inside everything

He is strong

V 3 Comments
29 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

30 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

31 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.

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

Gwen should be number 6

Gwen is not an alien she is a character

Gwen is the 6th most powerful character next to alien x, dagon, paradox, verdonna, and sunny

32 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

33 Articguana
34 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.

35 Ultimate Rath

He is like a wrestler

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

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 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

37 Ultimate Spidermonkey

What is stronger than eon

They made him weaker then spider monkey

They didn't

He is not here is higher! ¡! ¡!
!

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 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!

40 Shocksquatch

Shocksquatch got amazing strength

41 XLR8

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
Cool
And my favourite

42 Ultimate Invincible 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

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

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 Spidermonkey

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

47 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)

48 Ultimate Swampfire

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

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

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

49 Ultimate Big Chill

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

He can freeze anything

50 Nanomech

Its most dangerous attack is bio-electricity which can damage giant species and it first appeared on the movie " Ben 10 Alien Swarm"
