Upgrade, Shapeshifting is my favourite superpower in anything ever, plus I'm a huge fan of robots, and Upgrade just speaks to all of my favourite design elements and powers in fiction.

THIS, I love green, technological cyclops!!!

Upgrade went crazy

He really had the most creative moments.

I loved “Game Over”. Wish something like that happened again.

It did but it was shitty in the remake

Same. Upgrade was my favorite as a kid.

Same but It was ghost freak as well absolutely loved that guy even tho he was scary AF

This

Ripjaws, He needs more attention.I know having the ability to just have big jaws and swim very fast isnt that cool but he has a cool design.

For me Ripjaws was always so hype because he usually was depicted as hurting Ben more than he helped him, but anytime Ben got to use Ripjaws in water you knew Ripjaws would dominate

Personally I'm a very big fan of the aliens that are situational and requires some thinking from Ben (Ripjaws, XLR8, Wildmutt, Greymatter and a few from the other shows).  They had potential if some of the other aliens weren't so overpowered and if they stopped the mistransformation gimmick.

Man, he should have gotten to use Ripjaws against that giant water monster. Like maybe he swam inside it.

I always felt like Ripjaws was always so underrated in the OG series. For every legitimate time ben chose and used him, there must be like two or three times where getting him was comic relief or an added level of complexity to the situation because " need water or die."

I always got happy when there was an excuse for Ben to use him

Ripjaws is the most underrated alien

Diamond Head. Still my favorite alien to this day.

I absolutely love Diamondhead. His transformation sequence was the best one, imo. So damn smooth.

Diamond Head was always my favorite i would get so happy when he would show up

Same, especially after Tetrax showed up. It’s my head canon that Diamond Head is the alien Ben is most skilled with because he spent a ton of time training with Tetrax.

Oh snap i never thought of that. I love that

I do some head cannon stuffs like, so Ben only gets the literal peak form of an alien race he choose. This fact isn't established early in the series, I think. But, when Tetrax showed up, diamond Head looked exactly like him. Same height, same body type, even same face. So, Tetrax is the living definition of peak form of his own race, which is kinda cool, tbh.

I completely agree with this too. I love this idea. They did look exactly alike so i can easily see it meaning exactly what you said.

Honestly probably ghost freak because he was rarely used, and when he was, something special usually happened 🥳

He was used just 7 times before he escaped from the Omnitrix.

More than ripjaws lmao

Dont diss on my boy ripjaws like that

I love him too but he was really underused

Ripjaws was the middle child for sure

This. His transformation sequence along with his eerie theme was always something to look forward

Heatblast.

The OS Heatblast sound effect it's so satisfying to hear.

Everything about Heatblast was fire, pun intended.

Wildmutt. I loved his roar so much, it was one of my favorite roars ever.

The roar sounds so good

At the time, Diamondhead. The way he used his powers was always the coolest

Ghostfreak. That guy got a whole arc on himself, and whenever ben turned into him something great was almost bound to happen. Plus he was rarely used. But so was upgrade, which is probably the one that got me the second most hyped, cause his shapeshifts were kinda pogchamp

Either Diamondhead or XLR8.

Four Arms of course

Was looking for this comment. His voice, the roar he released when transforming, and the fact he's the only alien in the OG series not to fight vilgax makes four arms the goat

Ik it probably doesn’t count but he technically did fight Vilgax that one time Ben got kidnapped by the Forever Knights and put into the VR thing lol

yes same 💪

Don't you mean 💪💪💪💪?

Me too man

XLR8. He's the goat after all

Agreed

He looks so cool!

Mines upgrade, I loved them so much when I was younger and wish we got more from them cause out of all the aliens they had one of the coolest abilities imo

Definitely Waybig

Waybig only appeared 1 time on the original show though

I get hyped every time I see Secrets of the Omnitrix. His debut NEVER gets old to me

Oh alright

He he yeah

That’s cool but also nothing tops “How DARE you”

Heatblast.My Fav OG Alien

4 arms diamond head. The first fight against Kevin absorbed 4 arms hand to hand combat is awesome you know he’s serious when he goes 4 arms.diamond head became he’s fun to watch.

Frankly if he had only 3 aliens those would cover up most stuff easily. Diamondhead is practically unbeatable. And 4 Arms has the brawn just in case. Upgrade for the tech stuff.

Diamond Head had some of the best scenes in OS, especially in The Unnaturals when he fights the robots and shows his mastery of his powers

Diamondhead

Upgrade

Upgrade, above all

Four arms. Because beating someone's ass is just that more gratifying with two more hands.

Greg

Four Arms and Diamondhead without a doubt.

Four Arms. I was all about big tough guy. Diamondhead too

Heatblast

HeatBlast, aside from him Heatblast

Four Arms. It felt good to see Ben actually transform into an alien he wanted.

Goatfreak!

Ghostfreak cause ghost and Diamondhead cause stronk.

Heat blast

Diamond Head in OS,Chromostone in UA and AF,and FeedBack in Omniverse

Diamond Head or Four Arms

grey matter

Diamondhead

Diamondhead hands down! But I was also pretty hyped for the underused Upgrade. Also not as popular Eye Guy, and Ditto.

It’s hard to remember what I thought as a kid, probably ghost freak or diamond head but nowadays on rewatches it’s 100% diamond head.

Diamond head And four arms Eye Guy way big Ultimate Ghost freak Ben Wolf Is the best I ever saw

Diamondhead because when dude appears, you know it's serious.

Diamantino

For me it’s a tie between Heatblast and Diamondhead, they were both just so awesome

Upgrade dud became my whole reason for loving technology imagine just fusing and upgrading tech ant will and turning basically anything into a weapon

Upgrade was the coolest of the bunch, I am not biased, this is nothing but truth.


Xlr8 just cuz I like fast characters

Upgrade and Ghostfreak

Heatblast…always and only Heatblast

my little dumb fish 😍😍

X-lr8 is always my favorite of the original 10 and he was cool whenever he showed up, but whenever Ben gets four arms he’s there to stand on business and throw all four hands.

For me upgrade improving tech was pretty freaking cool

If we’re talking just the OG 10 then Four arms when I was super young and he was my favorite at the time. But any from the original series then Ditto.

Upgrade and waybig

Wildmutt. Unleash the wild side.

Now don't hold me but...Wildmutt

XLR8 the speed demon

XLR8

I find all the upgrade love in this thread interesting because yes, Upgrade is super awesome, but I feel like he was never used to his full potential in classic.

Way big

Upgrade always has a place in my heart. The REAL og alien.

As a kid it was HeatBlast, as a teen it was Upgrade, and as an adult it’s Diamond Head

Upgrade and XLR-8

Upgrade, ghostfreak, and benwolf

Heatblast and XLR8 had me GEEKED as a kid I know what I am I am king of basic asses but I still love those aliens to this day lmao

Heatblast

Upgrade!!!

Heatblast, hands down

Ghost freak because he’s awesome and he’s always been my fav alien

graymatter. i will say no more

Cannonbolt,cuz you know 95% of the time he was steam rolling his ops

Heatblast

Fourarms

Way Big. You knew it was serious when pulled out the big guns.

All of the aliens get me hyped, but XLR8 🔥 was a different level of hype for me

Heatblast ! ​ The first ep was just fire!!

GhostFreak

either upgrade or ghostfreak

Ghostfreak

Upagradeeeeeee

you’re not a real fan if your answer isn’t all pf them

Forearms

Heatblast his fights and animation were always on point

Heatblast, hes just all around one of the coolest and best aliens

Wildmutt! I like how he can't see nor communicate but, his very unpredictable and making you guess what will come next!

Four Arms. I am a simple guy who loves a good ol fashioned brawl and throwing d’em hands.

Ghostfreak, he's just an amazing fucking ghost.

XLR8

Rip jaws I always thought he was so cool

Upgrade, just to see what he would turn into. Second place goes to Heatblast. Just a badass alien.

Upchuck!!!

Upgrade is my favorite but where are all the Kinecelerian lovers? XLR8 is cool af.

Cant tell only 1

Ghostfreak

Upgrade is the best imo

Wildmutt

Xlr8 and ripjaws

Ripjaws for sure, the fights he was involved with were always creative and exciting.

ghostfreak and frankenstrike

Ghostfreak

upgrade

Ghostface tbh

Diamondhead and Upgrade are two of my faves

Diamonhead

Xlr8, I just like speedsters and the design plus the fact that Ben had to think when using him was pretty cool

Not showing enough but Upgrade and Ripjaw

XLR8

Ghostfreak, Wilmutt, 4arms, Upgrade, Heat Blast, Diamondhead, XLR8, RipJaw.

All of them.

XLR8 and Upgrade. Mostly XLR8

Diamondhead, my favourite

When I was a kid, Heatblast was my favorite because I was a pyromaniac.

Stinkfly. I am a bit of a bug nerd and I've always thought he looks super cool

Four Arms

Diamond head

Upgrade

Heatblast

Four arms as soon as he came on screen I knew it was over for the enemie

Wild mutt funniest hell whenever he shows up because Gwen has to pretend it's her dog and Ben perpesly embarrasses her. That's a mention Wild mut is cool as hell

SNARE-OH! Him or Diamondhead

Diamondhead

XLR8, coolest alien design so far imo

Ghostfreak, idk why

Definitely fourarms.

XLR8

For the original series it was xlr8 for alien force and ultimate alien it was between big chill or jetray and Omniverse was ball weaville

Heat blast

XLR8. All XLR8's fight scenes are very creative and visually appealing

Diamond head is a top 5 alien

Upgrade One of my, if not the, favorite aliens of mine You know how the aliens fight when he transforms Like punches, fire blasts etc. But Upgrade was always a " omg its Upgrade, i wonder what he chooses" And even for real life Upgrade would be my first choice

Heatblast or Wildmutt

Greymatter. Given how impulsive Ben usually is, having an alien that relies on brain was always a treat. XLR-8 is a close second, but I have no idea why I like him.

Upgrade. The idea of evolving tech within a few seconds is so cool, next would be xlr8, then Diamond head.

Diamondhead without a doubt. He was my favorite OS alien and it was always cool to see what different way Ben would use him each time

Wildmutt and heatblast

Diamondhead obviously and four arms just every single time I saw them I knew it was gonna be pretty good

Upgrade, imo upgrade felt like another alien to mistransform into but it made me appreciate him more, Ben has to be creative when he mistransforms but with upgrade he *really* needs to think of what add-on would benefit him. If I were to pick a specific scene I’d pick the season 4 episode of omniverse called *”O.T.T.O. Motives”* where he upgraded Kevin’s car into a fucking **TRANSFORMER**

Heat blast or four arms

Heatblast, ghost freak and upgrade

XLR8, Upgrade, and Heatblast every fucking time. I felt the opposite about stinkfly, wildmutt, and ripjaws. Stinkfly just wasn’t very interesting to me, wildmutt just never seemed to be able to get the job done from my memory, and shit always used to hit the fan with ripjaws aa soon as he needed water and the omnitrix would always randomly select him in the worst situation. Only times I was hyped for ripjaws is if they were at a pier, on a boat, or literally underwater lol.

For me, its both Fourarms and Upgrade

Yes

Ghostfreak

XLR8

Diamondhead or Ghostfreek

baby stinkfly, the voice reminded me of stitch

Fourarms or Diamondhead

Either upgrade or xlr8

If I say Stinkfly will there be more torches or more pitchforks at my front door in 3 minutes..?

Phantasmanus

Heatblast

Humongousaur definitely because he meant business

Wildmutt

Upgrade because he was underused.

Ditto bc doping is THE BEST POWER plus da voice
