The Top Ten

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
[Newest]It is the strongest alien ever.

2Ultimate 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
[Newest]He is the best

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
[Newest]Way is very big alien and he is very powerful

4Ultimate Humungousaur
His very big and can shoot missiles a shot gattling bullets
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 the best he can even defeat way big he should be the third

5Ultimate 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 very powerful.
He can change to every alian just by saying it.
After all he can change to all alien.
He is every alien! He should be number 1!
[Newest]But yet he can't beat alien-X

6Ultimate Echo Echo
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!
Ultimate Echo Echo can knock almost anything out easily
The sonic plate is awesome
[Newest]He can blows any aliens ear with his sonic ear

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.
[Newest]Alien X created the entire universe and everything in it with just a blink

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!
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
[Newest]He is very strong and he has crystal powers

humongausaur is strong enoung to bench press pick up truck. and his strenght only increase with his size
Humongasaur is strong enough to hold way big
The strongest at ultimate
He's getting bigger and stronger
[Newest]No alien can beat alien-X

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
It can suck opponents powers
He connects with Ben the most and beat a giant malware who even way big couldn't defeat
[Newest]He and take energy away and dish it out 10 times stronger

The Contenders

11Four Arm
4 arms, mean double the punch, He could fight any monster and win! The strongest by far.
Well four arms is faster strong because he is faster than humunousaur and smarter then rath
I love four arms he can kick everyone s butt
[Newest]Because he was chosen for a feat of strength when competing.

swarp fire is powerful alien because he never broke
swampfire might look a walking compost heap. but he's the one of ben's strongest alien
Swamp fire should be way higher

Ben victor has an electric body that is a good advantage for his body
That is so not true

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

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.
Let me tell ya something!
I am so not gonna leave alien-X on top and will soon beat waybig he is just a chump!

His power is he can end gravity
Gravattack could move a planet and a sun, I'm pretty sure he'll soon be able to move a solar system
GRAVITY POWERS, just send the others aliens into space using the power.

there's more to this giant glob of goo than meets the eye. goop is able to change of his body at will
It is the best alien it should be first the most powerful alien who produces dangerous acid su
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
[Newest]Goop also throws out acid and can melt metals

18Big Chill
Big chill can pass through solid matter and drop the temperature of anything he choose to nearly absolute zero
He can change the temperature of a place and is invisible

Absoultely epic can upgrade anything including your face
Technomorphing on a planet scale says it all

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 number one when he's in a fight he can just slow down time and beat everyone up
If you can control time your over powered

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 unlimited heat abilaties and could melt anything with supernova melt downs mostly when he is 5 years old

He is very intelligent and can make electrical storms

23Gwen Tennyson
She can use her mana for protection, levitation, flying and picking up things!
Gwen is not an alien she is a character
Gwen should be number 6

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

He can move through people and can scare his apponents to make them forget what he's doing.
He is so strong he escaped the omnitrix! <3ghostfreak

Shocksquatch got amazing strength


28Echo Echo
he may be small but this living amplifier packs some serious power echo echo produces steel shatering sonic waves
He can attack with multi sonic waves at a time. He can also multi himself.
He can make a sonic wave and can make ma ny copies of himself

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

30Ultimate Spidermonkey
They made him weaker then spider monkey
They made him weaker then spider monkey
They made him weaker then spider monkey

31Kevin 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?

32Ultimate Feedback

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

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

35Ken 10
The ben 10 of the future

36Ultimate Alien X

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

38Professor 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

39Ultimate Swamp Fire

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.

41Ultimate 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

42Ultimate Big Chill
It is very good alien I like it it deserves a chance in to 2
He can freeze anything


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

45Ultimate Rath
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
Ult rath is the most powerful alien of ben ten ever. He can defeat alien x very easily

46Ultimate 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

Ben-wolf has superior leg muscles and can jump incredibly high as high as the "yenodoshi"

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)

49Ultimate FourArms
He is ten times stronger than normal forms he has extra weight now he can defeat humangasore easily

50Ultimate Terraspin

51Ah Puch
May still be alive but can take on original ben ten, gwen, the forever knights and grampa max in a hasman suit if only the roof stayed up



54Grey Matter

55Water Hazard
Water hazard is the strongest. He can destroy anyone by pouring water and controll it. He should be number 1
He is the prisoner of aquqguana. His power itself the water he can even defeat spider monkey and chromastone, I think he should be given eighth place.

Wait, Wildmutt wasn't on the list before this? Wow! Wildmutt can jump really far, has great hearing and smelling abilities (which can sometimes be superior to seeing), etc. He also seems to be able to rip a chunk out of almost anything. Wildmutt may not be the strongest, but he certainly deserves a spot in the top 20.


58Ultimate Swampfire

He should escape from the watch and have a omnitrix and become a better hero the ben 10 and his real name should be reptilian

An gloop of technology which came from baily (he can turn into some amazing weapons
Ship is basically a mini upgrade so if upgrade is on the list so should ship.


62Coach Finn
Much like a transformer he is a robot in disguise and has two shoulder plasma guns (with a whole team of robot people a robo president too)

A robo-rhino created by dr animo with an electric net an a plasma horn charging at high speed



66The Mummy

67Galvanic Mechamorph

He can create a black baem that can absorb energy from any living creature until nothing is left by becoming very powerful.

The Most powerful villain and has powerful mystic powers is a bit like shuma Gorath

70Eye Guy
Can see from every degree (360)
He can see and

Stink fly should be number one. He shoots goo and flys

72Rook Blonko
He has the proto tool which obviously could do anything he should be number 1


Rumble is the best

"Are you kidding lodestar can influence anything metal he should be number 2 on this list"

If there's someone Cald shadow he can be a shadow in places And he can strech as a shadow he can hont people it would be awesome for someone cald shadow thanks people

Although only a very short appearance the yeti, where in the episode where ben 10 meets terraspin, almost beets four arms up in the north pole
He's cool and brain storm helps him by destroying the hypno head band that dr animo used to defend himself

He deserves to be number 1 even though he's not my favorite character he has all the abilities of the great ben 10 himself

79Forever Knight
He should be 76th

80Evil Way Big
Super intelligence, super strength, enhanced durability and cosmic rays I say no more

81Ultimate Aggregor
He deserves to be the best even if he is a villain
