Ten Best Ben 10 Aliens


The Top Ten

1 Diamonhead

I have never heard of Toe Pick. Who the heck is this guy? I think Swampfire should be higher and that Diamondhead should be either 1 or 2. I would say that Swampfire deserves to be number 3; Waybig, number 4; Cannonbolt, number 5, and Toe Pick number infinity (you see, I looked up a picture of Toe Pick and he looks like a bad guy, so get him out of the Codon Stream, Azmuth! ). This is just my opinion, everybody, so if your don't agree with me then so be it.

Diamondhead is the best! He is made of hard diamond and can make as much as he wants! He can detect any kind of crystal under ground! He can regenerate any body part. Even if he exploded by a bomb, he would still be able to regenerate back together. He can take large boulders of diamond from under ground and launch them at people. This guy is crazy, not to mention that he can turn his diamond hands into long swords or guns that shoot lethal diamond blades

Diamond head has to be number 1 not toe pick so please change it! Diomond head number one alien!

He is so awesome and the fact he can absorb and reshoot lasers and encase anything in crystal makes him even better

2 Xlr8

This dude is awesome I love him he is so fast he's just wow!

This alien is super fast. He can win ANY race!

HE is the fastest alien from the omitrick and with his super speed he can give a super fast punch faster the punch the bader it will hurt.

Xlr8 is the best in style. He is so fast just like wind. Love this alien.

3 Heatblast

Heatblast is my favorite alien. He deserves to be the first in the list. He could so beat Xlr8 in a fight. Diamonhead may be a challenge but I think Heatblast could still beat him. He could even fly and his moves are more fatal than most aliens. This alien is Ben's first and most used alien. He is also the one Ben has most control with. Also who doesn't think an alien who could use fire or no be fire isn't cool. This reason is why I think this alien is most strongest and the alien that is Ben has the most experience with.

I think heat blast should be no.2 or 1 I understand that Xlr8 is very fast but still Heat blast doesn't have much of a problem with the fast enemies there is also a episode where Ben gets a cold and the only one of Ben's aliens that get they're abilities changed was Heatblast I think heat blast would have been stronger if he was ice but to tell you the truth I don't know if he would beat Xlr8 as fire but as Ice I don't see why he couldn't freeze fast enemies.

When I first saw this alien I immediately went crazy! I mean look at it! It's a living fire alien. Also heatblast has the most badass moments and many screen time and it's Omniverse design is way cooler! And let's not forget he's the first ever alien to be introduced in the whole been 10 franchise!

4 Alien X

It can control everything with it's mind. That's it.

His mere thoughts can become real and he once recreated the universe when it was destroyed, he is omnipotent and can warp space and time to however he wishes, but 2 voices must agree to do it.

Ben's strongest alien is alien-X. In episode"the forge of creation" kevin mentions that it can just blink an you will be gone so it deserves to be the strongest.
It is so strong that it doesn't have an ultimate form because it can do everything even make a copy of the entire universe and everything in it.
It doesn't have an ultimate form because there is nothing else that can be added to it it can already do anything.

Strongest alien

5 Ghostfreak

Ghostfreak is creepy, moves his eye in the black lines in his body, and was awesome.

Of course, the whole "true form" thing, and him becoming a villain was dumb, but still the best alien.

Ghostfreak can go through walls and moves his eye in the black lines and he can go inside people and he is one shadowy ghostfreak

Ghostfreak is my favourite alien. I basically like creatures which can move through things. - Animefan12

Ghost freak is creepy, powerful, and wayyy better than Diamondhead, who is just shards of diamond-like material. He actually broke once and I just don't get why he's one

V 21 Comments
6 Fourarms

He should have been higher up on the list. He can lift things several times his weight - chima23

He was always my favourite

R you kidding me? He must be at number 1 or 2. He is super cool. Ooh-yeah!

He's just cool my dudes

V 18 Comments
7 Swampfire

A walking plant with regeneration powers and fire blasts. It smells gross 2.

Swampfire ROCKS Man!
I can't believe it isn't in the top 10 list
This should be at the top

He is like an improved version of heatblast, he does not only produce fireblasts, he can also generate plants, throw explodig seeds and regenerate himself. Should had made the top 10

My favourite ailen

8 Wildmut

One of the best designs of a character I've seen! It's also different from the others and it's mare likely to exist in real life (not all beings are humanoid! ). Original powers too that are awesome kid of make me remember daredevil! Classic alien deserve better ranking

Why isn't Wildmutt in the top 10? He just looks awesome, for starters, but he has superior smelling and hearing abilities that make up for his lack of sight. He can climb well, jump high, bite things to death ( if he wanted to) and much more. Yay Wildmutt!

He isn't the strongest but he still is awesome. He has hearing and smelling abilities. He is also a good climber, jumper and he has jaws that can rip things - chima23

It actually looks like an alien! Nobody speaks English in space, and there aren't enough nonverbal aliens! Imagine the potential conflicts and storylines that could've propped up!

9 Upgrade

Upgrade is my favorite alien because he can merge with any technologic machines to upgrade them and make 'em stronger he can also shoot lasers out of his eyes which is very awesome and cool not to mention he can transform into liquid to get out of any sticky situations also his stretching makes him a very hard opponent to attack and hurt anyways upgrade is my favorite and I'm glad he made it into number 9

Upgrade may seem to be only of any use around technology, but his stretching allows for him to, like goop, dodge attacks and get through small places. Upgrade may not be invincible like goop, but goop relies entirely on his anti-gravity projector. All in all, upgrade is an amazing alien.

Upgrade can merge with anything and can make it better he can also shoot laser from his eye he is just awesome I like him and he should be at 1 place he can upgrade any thing and he is the best alien

He's the goat

V 26 Comments
10 Atomix

He is the second most strongest...

I think he is the best he looks so cool to so I really think he should be number one.

An awesome alien and one of the best and the strongest alien I very seen

I agree He destroyed billy billions tower.And killed the evil version of ultimate spider monkey and fried Him like A piece of toast in a frying Furniss.

V 17 Comments

The Contenders

11 Waybig

Waybig can cause an earthquake with a one punch... His punch can overwhelmed any enemy alien

this is the best because he's huge strong and can blast powerful beams

The biggest alien that Ben ever had

Look at that size!

V 41 Comments
12 Rath

rath is the most strong and funny alien of this list, he look like a fusion of hulk and wolverine rath is the best

Rath is awesome. He's so funny. He makes the show more entertaining. Also, I like when he says "Let me tell you something." I like when characters are stupid and aggressive.

Rath is like a WWF rip off. He talks like Hulk Hogan 'LET ME TELL YOU SOMETHING' and calls people with long weird names like The Rock (Dwayne Johnson). And he also uses wrestling maneuvers.

Let me tell you somthing the top 10 users rath should be number 1 rath is the funnist and most loved by ben 10 fans this is raths website you don't just come in to raths website and make him number 12

13 Feedback

Feedback is a pretty sweet alien, he can absorb electricity through his plugs and shoot it back out, he's also athletic and can move easily and quickly and moves faster on electric wires

Feedback looks like a beast first of all. He is ben's favorite alien and is super cool looking an confident. Plus he like an electric ninja. His powers are to absorb, channel, and shoot back energy

He is fighting with the best style and he is the most confident

He’s ao amazing no wonder he was bens favorite alien in omniverse he held a universe creating/destroying bomb the only other transformation that has done that is alien x

V 27 Comments
14 Stinkfly

He can shoot snot out of his eyes what's cooler then that.

Stinkfly! You Suck as Your Yuck!

WHY so low people I just wanted appreciation for him!

Wow look at the time. gotta fly

15 Cannonbolt

One thing about this alien is that it has no special powers. It's an alien that can roll up into a ball and do just about anything a normal ball can do with a hard protective shell that can bounce off certain attacks. Plus, it was the first of the original aliens to get an ultimate form.

Cannonbolt is pretty much an oversized bowling ball.but he is still really awesome I just love it when he rolls up into that shell of his and I like ultimate cannonbolt even better I mean what isn't't cool about a giant rolling ball of metal that has super speed.

There should be an infinity trix like ultimate trix and cannon bolt should be fire cannonbolt...

He is my favourite alien as he could deflect lasers and also can escape from fights
he is cool.he can also withstand high temperature.

V 9 Comments
16 Blitzwolfer

I only have 5 words to summarize his paragraph...BENWOLF IS JUST A BEAST!

Benwolf, blitzwolfer both are very cool.

Benwolf is defitely the best alien EVER! His jumps are crazy! He can do that sweet sonic blast thing. He's also strong and fast. He's got built in weapons (claws and teeth), plus he can aim his sonic blast at the ground to jump even higer! This alien is number 0ne or two in my bok, even though ben never really named it yet.

Benwolf should be no. 2 right after swampfire.

17 Humungousaur

He is one of my favourite aliens

He's the strongest after way big gives me a feeling similar to hulk

Hi is my favorite alien

He is the best alien to go to when Ben has a tough situation requiring high physical strength. - AidanYYao

18 Articguana

This alien is one of be 10,000's he can withstand temperatures of -50 and below, can emit a visible co2 breath and can freeze objects like big chill

He can freeze anything with an awesome blast. It was also revealed in Omniverse that 16 year old Ben unlocked him. He can even make useful sculptures out of his ice like a slope!

He breathes ice like a dragon breathes fire, he appeared in ben 10 thousand and can freeze almost anything, including magma.

This alien was the strongest in Ben ten wrath of psychobos the android version

V 8 Comments
19 Eye Guy

He can shoot freezing blasting beams from his eyes and he has lots of eye's and is yellow eye but his face has only ears and mouth and wears black pants

Eye guy is one of my top favorites. He can shoot lasers out of any of his eyes. He should be more up the list. He should have appeared more on the show - chima23

Although I love eye guy but he isn't worthy enough for number 13 I think grave attack deserved to be on this number more

He is better than wildmite and ripjaw and even better than wildvine

V 3 Comments
20 Big Chill

It can turn invisible, freeze things, lower the temperature to absolute zero. And fly.

Big Chill is my favorite alien. But not in ominverse because of his huge stomach.

Switched from Ghost Freak to Big Chill when I first laid eyes on him. I mean, come on, the dude's intangible, can handle temperatures from both extremes, and his ultimate form is so hot it's cold. Not to mention his design is just so coool

Should be in top 10. Just an amazing alien

V 18 Comments
21 Toepick

Toepick can scare anyone.

Toepick sucks his only power (isn't even a power) is scaring people. They can just close their eye's

Toepick is so powerful that he can also lose ultimate way big because of his scary face.

People say toepick can defeat alien x. Alien x could beat anyone he can blink and you can die. He can do anything.

V 15 Comments
22 Rip Jaws

Its awesome perhaps my favourite because I am a swimmer

Ripjaws has always been my favorite and is one of the most underrated aliens of them all.

He's my favourite too and it's sooo sad that ben was rarely ever ripjaws in the original episodes. I think that Goop, Big Chill and Ben Mummy are pretty underrated too.

23 Ultimate Rath

Most fun character, agile, strong and even though he rushes into everything his dialogue makes him funny. I look forward to Ben transforming into him all the time

He is better than Rath

Ultimate Rath has 2 claws have you seen rath? Well if you haven't his claw can just slice through things without rath even doing it ex: On the episode Primus in Alien Force azmith transformed into rath and the claw cut through the boulder but azmith only put the claw into the boulder! So em 2 Claws...? Help all existance?!

Yeah let me tell ya someing people(with my claw)I am the best alien of all time

24 Fasttrack

Fasttrack is speeder than xlr8. This alien is one of the beautiful alien. I like it

His personality is like Quicksilver from Marvel

Why is this alien so high?

Remember me the methed out feline alien who is so forgettable but still XLR8
Is better

25 Ultimate Echo Echo

Only ultimate echo echo defeated ultimate kevin11

Ultimate Echo Echo is the best ultimate form, and one of the most powerful aliens too. His sonics disc allow him to attack from far away and he can even kill someone with sound waves.

I believe that because of his cloning ability and the fact that he gets louder for every time he should be number one.

An ultimate of my favorite alien and looks like soundwave from transformers

26 Ultimate Big Chill

Ultimate big chill is awesome! The best catch phrase ever! "So cold it burns! " 2 in 1! Amazing! And the babies are so cute! It can freeze up to 100 people at once or create a sheild/dome, it's freeze causes damange without fully destroying its enemy to which the point that it passed out. This Alien is awesome!

It ghost like picture scare me but its fire freezing power is cool


Its fire red body and icy fire is awesome

27 Astrodactyl

He's pretty awesome because he can shoot energy beams from his mouth and plasma whips from his hands. His powers are just like jetray's from Ben 10 and Starfire's from teen titans.

He's my favorite alien

28 Chromastone

BEST ALIEN EVER PUT ON BEN TEN! HE IS AWESOME! He looks really cool and his attacks are so good. VOTE FOR CHROMASTONE!

Chromastone can absorb energy

Chromastome has the power to absorb and utilize a lot of energy at a time. Beyond this, his other abilities -- flight, extreme, durability, and "energy intangibility"-- make him outclass his other notable energy absorber: Feedback.

Wow I hove wondered

29 Ben 10, 000

Ben 10,000 is the best one cause he is better than Ben 10 and Ben 10 transforms to any alien but Ben 10,000 has a variety of 10,000 aliens.

Ben 10,000 is like the best.

Duh has 10, 000 ALIEN forms

He has 10,000 aliens plus a biomnitrix to mashup his aliens.

Plus he is the most powerful as he has alien x too

30 Spider Monkey

He is like a quadruped Spiderman; always swinging around on his solid steel webs, he is always laughing with a great sense of humour and has 4 hands, but he has a small and fragile body.

SpiderMonkey is extremely flexible, and can swing and jump just about anywhere, he can climb and shoot web too.

A spider and a monkey combined that can walk on walls and shoot webs.

Stronger Than Spiderman

31 Ultimate Humungousaur

This alien is even more like a dinosaur than humungousaur.

The guy can shoot rocket from his fists

32 Ditto

Ditto is the funniest and coolest alien. He can clone himself, but each clone acts on its own will, causing him to argue with himself. A lot. He is the perfect combination of clever, annoying, and ridiculous, that makes him absolutely hilarious, like the Animaniacs (Yes, I love the Animaniacs, sue me.) He also fights VERY well, pummeling his enemies into oblivion, and has a creative weakness ("ow! I stubbed my toe! " "Ow! I felt that to! ") Lastly, I just want to say I could quote Ditto for forever. "How about a little one-on-one?...make that, 'one-on-none! '" "We promise we won't bother Gwen anymore... But we didn't say anything about him! "

The way that Ditto's one of the only ones that can clone himself, not to mention the AWESOME way the Ditto's kick butt, is a rocking alien (or aliens! ) you would not want to mess with!

Ditto is a comedious alien with an interesting and induvidual personality. Or aliens. It's hard to tell when you can divide yourself by an infinite number. But being voiced by Rob Paulsen does give it some extra brownie points. I absolutely love the way that although it has power in numbers, it can't really do much if one of it's copies or selves are eliminated, making it the perfect weakness for an otherwise invincible alien. But all my blabbering aside, it's one of personal favorites.

I have always loved every second of Ditto Screan time and I wish we'd gotten some of him in Alien Force and Ultimate alien, Echo Echo may be stronger, but Ditto's habbit of arguing with himself at time's is just fun to watch

33 Upchuck

I love this alien, he is the best! He don't eat to live, but lives to eat! I really don't know why he isn't on the top ten...

He's the best ever

34 Lodestar

He controls metal

This aleins personality is magnifying an he's able to control metalic objects

35 Eon

He will just kill everyone

Diamond will kill him

Eon is not an alien
He is just an alternate evil version of Ben Ten who came from a parallel universe

I wonder what ultimate eon would look like?

Eon is awesome.

36 Diamondhead

Why are there two diamond heads? This is so stupid and dumb.

I agree

37 Eatle

He should be top 20. He is Upchuck and Rath in 1.

Hi is cooler than upchuck

He is pretty cool

He is based on a beatle and he is like upchuck

38 Ultimate Cannonbolt

I love ultimate cannonbolt because when he rolls up, he has spikes all over him. That would hurt any dnalien in his path. He is awesome.

He's even immune to radiation as shown in "Too Hot to Handle."

39 Jetray

He is so awesome plus he's as fast as xlr8 or maybe even faster!

His laser's attack the nervous system, making extremely dangerous to animals.

It has laser beams with it's eyes and it can fly.

Jet ray can fly the fastest and can stick a perfect landing out of hyper space

40 Goop

He is a puddle of goo, with a hover device that shapes him, he is pretty strong and can squeeze through small places, also when he's hit he can instantly come back and kick ass!

It is the best alien ever! And if you don't think so your horrible

Come on guys, you know goop is a lot more dangerous than swampfire. Goop should take his place

The best alien

41 Ultimate Spidermonkey

Ultimate spidermonkey is defiantly one of the best aliens out there.

stinkarms is cool because he flys and he has muscles to smash through walls he can lift a truck while flying he can shoot slime while lifting a trampoline he can jump so long and fight while he is flying he can rip ghost freak of his body and smash ghost freak through a wall so far that he is in light so he can die he has a tail from stinkfly he has four eyes
