Allen O'Neil being best boy for 20 minutes straight 

Three reason why Allen never die, 1) his loyalty to morden is beyond anything 2) he promise to his wife that he will come back home soon, that why he refuse to die 3) the games need him and the fan also love him cause he is the best boy

Allen: "See you in hell." Me: "So that was a f**king lie."

How are you still alive ? Allen O'neil: I have no idea.

It's appropriate that Allen on his own is more powerful than Allen piloting a giant mech.

Allen O'Niel: C'MON BOY! Eri and Fio: 😞

this one voice actor recorded 5 lines and created a legend that persevered for over 25 years

Dude, the fact that Allen is so freaking buff to where he can continuously hold up half of a gigantic mech. Man's be STRONK!

HE CAN BREAK THE METAL SLUG IN TWO... WITH HIS BARE HANDS !

This guy literally never give up

3:23 Allen helping Marco (Tarma, Eri & Fio) against the clones was an awesome moment, MS3 is always be the best MS

This man really just threw a grenade at his own comrade and said "go home to mommy"... I guess he could tell that guy wasn't bringing it

Allen : Gets eaten by an orca in X/2 Everyone seeing him on 3 and beyond : "Didn't you die ?" Allen : "It was greatly exaggerated."

1:45 if you're wondering how did he come back from this then you didn't know, he ate the killer whale not the other way around.

Allen: Allow me to just lift half of a giant robot.

Enemy: *is a girl* Allen: "Come on, BOY!"

1:47 that was not his bone. Thats the whale's

Just wanna remind y'all that this man never dies because he's too loyal to Morden and always promises his wife that he'll get back home (I remember there being actual concept art of his wife). Allen is like Dominic Toretto from Fast and Furious. Nothing gets between him and FAMILY!

11:24 once the robot loses it's legs the dude carries the giant robot, that's badass

The best boy, the best sergeant, the best father and the best soldier in video game history

Morden: * turns into a pretty girl * Allen: *busts into a jeep with his machine gun, thousand grenades and a homing missile cannon that can turn into a fucking pizza cutter in the battlefield* (Too bad he doesn't have hp and atk upgrade slots)

Ah yes, they merged Terminator with Rambo. Now that's badass!

Allen O'Neil got one of the most badass melee animation imo . he slaps you once and you are done for . i actually used to think he pull off his ammo belt from his machine gun and use it as whip .

The fact that we get to fight junior it's an honor. He even dismisses the machinegun and goes for the slashing mode. Junior surely takes up to his pappa

I'm used to being able to say "HERE COMES DA BOI!", but I can't say that about Allen... Allen is no boi. He is DA MAN!

He's the only character that doesn't look chibi. His sheer manliness stopped the artist to chibi-fied him

11:35 Allen rescued General Mordren after Jupiter King blown up. Nice. 12:55 O.o

11:35 - Am I the only one to see a display of *_FRIENDSHIP_* in this scene? Besides, Allen has a wife: I'm pretty sure he's straight.

*Alternative Title:* Allen O' Neil being a badass that he is for 10 minutes straight.

if Rambo was a Bad guy: Allen O'Neil

Allen O'Neil is a Chad. Don't change my mind

The fact that Julia doesn't say "c'mon boy!" Or have her own laugh makes genderbent Allen a huge downgrade

Always found funny how the terminator Allen dies with a Contra: hard corps sound.

I know Alen is never die.... He just Immortal on his nickname ... But he cannot stand with Abigail :V Tired being called Bald head

3:43 Allen: YAHAHAHA!!! "Burst shot" YAHAHAHA!!! "Burst shot again" YAHAHAHAHA!!! "Burst shot again" YAHAHAHA!!! 3:49 Fat Marco: STOP LAUGHING! I HAVE TO SAVE MY FRIEND!

*Playing as Either Fio or Eri* Allen - _"C'mon, Boi"_ Fio and Eri - 🤷‍♀️

YAHAHAHAHAHA!! COME ON,BOY! GO HOME TO MOMMY! YOU'RE MINCEMEAT!!

Honestly, we need Allen o Neil in Kof 15 as guest character with two more Metal Slug guest characters! That'll be awesome as hell, man!

4:07 Damn.. Fio is immortal..

I imagine if Allen was Kratos, saying "Come on Boi!"

1:45 I think that wasn't Allen's bones being spat out but the Orca being made to regret eating Allen as it is forced to spit out the bones from previous meals while Allen escapes from its stomach. Notice that only 6 bones in the human body correspond to those bones (the ones in the upper arms and both segments of the legs) yet the Orca spat out far more than 6 bones. 5:41 Did they really have to put the weapons there? Also, why did you include Allen's son and future daughter-in-law?

I like how the rebel army has really interesting weapons and stuff

The Heavy: Finally, worthy opponent. Battle will be *legendary!*

With such iconic lines like “Go home to mommy” “Cmon boy” And don’t forget “See you in hell”

We should all strive to be a little more like Allen O'Neil.

Allen when with pretty morden: Isnt this cute Me: Wait a minute, what the hell

Every metal slug fan are dying inside in this moment 20:51

Got killed many time even got eaten by whale but he always coming back like frickin terminator

The Code J version makes Allen looks too easy :V Look at that bullet speed (it's a damn machine gun)

Allen in metal slug attack: *kills about 50 Marcos, Fios, Eris, and God Will know what else at the same time* Allen in every other game fighting agains 1 Marco: Guess i'll fake dead

Allen : come on boy Eri : whut? Fio : whuuuut?

Dom Toretto: family? Allen: definitely. *MANLY HANDSHAKE.*

Allen O' Neil Machine gun:Big When U got the Machine gun:Smol

Regular Army: "ALLEN??? AGAIN? We thought you were dead!" Allen: "I was"

How to finally defeat him once in for all: *Send a picture of 096’s face*

I really wantmore games with graphics like metal slug, the realism in the animation just feels comforting to me for some reason

"Perhaps the heaviest things we lift are not our weights, but our mommies" -Allen O'Neil

Allen O'Neil: I can do this all day.

1:28 Best part

Aunque técnicamente es uno de los malos, es uno de mis personajes favoritos de la saga

Allen is more durable than SCP-682.

God the MS3D VA's are weird, The guys who did Morden and Allen did a great job though.

He only have 3 lines. "Go home to mommy." "Come on boy" "See you in hell" Occasionally he grunts and udder sounds of pain, but I think there is also the quote "You're dead meat", but it is very hard to discern in the airplane fight. He also laugh quite often too.

Damn, Allen. I just want to ask, how strong is Allen O'Neil? I asking because he can lift half of Super Jupiter King by himself.

He's not the best boy, he's the best god. He's an immortal entity 🙏 I'm not making this up he seriously never dies

1:28 팀킬 ㅋㅋㅋㅋㅋㅋ

Allen o'neil is the definitions of "Idiots never die" Only... he's actually super smart

Allen can tank A LOT bullets without any protection

분명 다른 무기를 들면 메탈슬러그 세상을 평정하셨을 분이지만 비겁한 수를 싫어하던 참된 군인이었던 탓에 그립습니다 ㅠㅠ

You know, this makes me wish they'll add a rival character like Allen in a Cuphead DLC or sequel. Basically a mini-boss in the run-and-gun levels that has almost the same moveset as you.

1:29 soldier: I thought we were friends :'v

Every new MS title is another level of Hell that Alan will see you in

Ah yes. Giant pizza slicer. I think i know what he will do after battle retirement

Allen O'Neil is just heavy weapons guy change my mind

I never even knew he had a name. I just call him the machine gun guy

5:33 Best part

This is one of the best TAS I have ever seen

I always found funny in attack how in an event it shows some scientist kills him (again how many times does he die) and the next time we see him in there is as "immortal". I think this guy is like kratos a man unwilling to die and returns back to the land of the living to fight you again

1:44 That shout, man🤣

가만보면 참 충성심 높은 호탕한 아저씨여. 등장할때마다 웃으면서 등장하시고 말이여. 적이면서도 밉지가 않네요.

4:42 Allen o'neil straight up became the terminator

Now allen is a super soldier that would never dies easily because of his loyalist and honorest to his general morden.

I used to think he was saying “De human power” but after. While I learned it was “See you in hell”

”戦車より硬いおっさん（公式）”キター！！

its basically dwayne johnson by: Korone ch watch her playing metal slug you will see how fun it is without the seriousness

man he's litteraly to good he can't even die lol

H E A V Y M A C H I N E G U N

Thats why I need Allen in KOF XV along Morden and his son. To rival Ikari Team

Allen O’ Neil more like Chad O’ Neil

Allen, the definition of. Whats death?

アレン軍曹はモーデン軍の憧れ

Allen: Come on boy! Fio: Excuse me?

El Rambo de metal slug 🤣 Era muy difical matarlo con 1 sola ficha me acuerdo cuando era niño

1:43 - See those bones? Those are NOT Allen's bones. Those are the orca's.

Bro love your videos always a big fan, but if I can add one suggestion, if there is timestamp for each character type it very good and informative for new Metal Slug fans like me.

Allen didn't die to the Orca he simply ripped and punched his way out of it's Body.

"Local man literally too loyal to die"

El es mi personaje favorito de metal slug lo vi por primera ves con mi papá en metal slug 3 en las máquinitas

Besides the video how on earth did eri disguise herself as a rebel soldier? Unless....... DID SHE SKIN A REBEL SOLDIER?! Now that's going into the abyss of the iceberg

Allen's laugh alone can bring end to famine

Never thought that kyo would be holding a gun.
