[Verse 1: Iron Man]
You know it's Iron Man, the iron one
And that's with or without the suit
Guardian of the human race
And I bring in all the loot
A mastermind to tell the truth
The Captain simply can't compute
A test tube hero
So you know where you can
Stick your boot
The one and only Tony Stark-
Yes sir, it's my given name
Made it to the top of the hill
But wasn't given fame
Earned my reputation
And you only took a shot
So you may be my elder
BUT IRON MAN IS YOUR POPS!

[Verse 2: Captain America]
Lets take it back to '41 when I was
Fighting with the Axis-
Powers, I'm powerful
And Tony Stark would be practice
The first super solider
The first on the front line
I'll beat a metal bitch down
I don't need a punchline
(Yeah)
Put on the suit
You'd still be a dead man
And by the time I finished
You'll be pissin' in a bed pan
The teams need a leader
And you're cut, so don't suit up
The captain makes the calls
AND YOU COULD NEVER FILL MY BOOTS UP!
[Verse 3: Iron Man]
I don't need to fill your boots
I'm the Iron Man, damn it
Leader of the Avengers
Even thought I didn't plan it
Became a protective S.H.I.E.L.D
And Guardian of the planet
Standing tall above the rest
And little Stevie can't stand it
I'll go Super Sonic Flight
Mach 3 in your face, Cap
Outdated, outmatched
Think it's time that you face that
Rising to the challenge
In the future like before
BUT YOUR AN UNGRATEFUL BITCH
SO WE CAN GO TO CIVIL WAR!

[Game Audio]
Iron Man: They don't call us Earth's Mightiest Heroes for nothing

[Verse 4: Captain America]
Let's go to Civil War
I've already been in the trenches
And you're an pampered punk
Ask Pepper, she'll be a witness
Created the villain Ultron
Stark, you're such a fool
But wait, you can fix anything
Since you are a tool
Unbreakable like Vibranium
Spare you if you're lucky
But keep talking trash
You'll get your ass kicked
By me and Bucky
I'll crush your metal heart
And let you die a slow death
Humming hail to the chief
AS I WATCH TAKE YOUR LAST BREATH!
[Verse 5: Iron Man]
This Star Spangled prick needs a lesson
And I'm gearing up
Iron Man backhand-
I can see you tearing up
Drop you to the ground
From the top of Stark Tower
No serum that you've got
Will ever equal Stark Power

[Verse 6: Captain America]
Wait
Let's not forget
It was me who spared your life once
Lights out for Iron Man
With one more right punch
I had to go rouge
But the Cap is still in action
I'm laughing at what's left
Of your sad Avengers faction

[Verse 7: Iron Man]
Hold up
Cap, it's gone too far
Thanos is on the way
It's time to team up once again
Avengers need to save the day
[Verse 8: Captain America]
Stark, I agree
I've had enough of our fightin'
Let's put the weapons down
And destroy this Mad Titan
