[Intro Chris Evans & Mark Ruffalo]
Captain America: Now might be a really good time for you to get angry
Hulk: That's my secret cap, I'm always angry

[Verse 1: Bukshot]
In my opinion I'mma tell you what I'm thinking 'bout
I don't bite my lip for no one I thought you done figured out
That I'm a living weapon yet this bomb is ticking loud
I'm about to detonate like a grenade with the pin out
I know they mental's weak, these Jedi play some mind tricks
These haters jellyfish, they swear my ocean's spineless
You see these Underground Avengers I conspire with
We so deep off in these trenches our career is timeless
See I'm connected to the corners of the underground
You don't wanna rumble in the jungle we don't fuck around
So fuck the industry, my attitude is shut 'em down
We'll show these bitches how we play and that we're tunnel-bound
I know that you can't stand the truth and won't admit this
I'm a factor in these streets and I'm on top my business
The way you think is how yo name got on my shit-list
Before I'm done I'll bend it over and you can kiss this

[Chorus: Jelly Roll]
Since they let me out the cage I'mma beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
King Kong on 'em (king kong on 'em)
King Kong on 'em (king kong on 'em)
I'm gon' beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
King Kong on 'em (king kong on 'em)
King Kong on 'em (king kong on 'em)
I'm gon' beat on my damn chest
King Kong
[Verse 2: Claas]
Yeah! Bitch I'm back, time for business
They never saw it coming, told 'em I had a hitlist
Now I'm getting ridiculous, n***as 'bout to go missing
I'ma take this over with drama I'm young and reckless
I'm right now beast on a mission, bitches I'll bite down
Other rappers trynna get loud like muffler just pipe down
Monster with that energy, kill ‘em call me that red bull
Sicker than these bitches, the beat is sick, 'cause y’all dead too
This shit's a movement and I'mma do it the best
Why the fuck you think we squaddin’ and now I'm pounding my chest
The wicked we never rest aiming for that success
I'm captain, I got a scar that's embedded up in my flesh
This merger is not a test, it's countdown into what is next
So buddy best call it Fury cause we about to impress
Yeah, ha
I said we about to impress
Everybody's 'bout to get on the wagon ride the express, yeah

[Chorus: Jellyroll]
Since they let me out the cage I'mma beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
King Kong on 'em (king kong on 'em)
King Kong on 'em (king kong on 'em)
I'm gon' beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
King Kong on 'em (king kong on 'em)
King Kong on 'em (king kong on 'em)
I'm gon' beat on my damn chest
King Kong
[Verse 3: Boondox]
I'm 'bout my business
Nobody wanna fuck up, end up on my hit-list
And I'm 'bout to rid this world that’s perpetrating counterfeit bitch shit
I'm poor that kick though
Run up and ditch your body, leave your body with a big hole
Sick dude with a sick flow
I'm crazy, I'm madness
Like walking with no big toe
Beast mode like King Kong
Mo' murder my theme song
You feel a little froggy jump Kermit up
He all over your ass like a green thong
Beat on my fucking chest
Strap on a fucking vest
Gorilla cap peeler, take a shot of Tequila, you wanna rumble in the jungle well be my guest
I'm jumping out the bushes just like it was '09
Like Bane left Wayne up on crutches Batman a broke spine
You're falling down on your knees, forgiveness, no time
The ice I got in my veins will leave you snow-blind
Avengers on a mission, they gon' be a strong collision
These haters keep on wishing they ain't make the wrong decision
I got a proposition, more like a premonition
Call up the mortician
Busting heads is a tradition
[Chorus: Jellyroll]
Since they let me out the cage I'mma beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
King Kong on 'em (king kong on 'em)
King Kong on 'em (king kong on 'em)
I'm gon' beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
Since they let me out the cage I'mma beat on my damn chest
King Kong on 'em (king kong on 'em)
King Kong on 'em (king kong on 'em)
I'm gon' beat on my damn chest
King Kong
