(Battle starts at 0:20)
=== Samurai Jack: ===
I fail to see how this slacker's worthy of battling me
I'm slaying entire armies while you're busy fighting off bullies
In this battle, you'll be shot down like your friend by that terrorist group
Slaying you like Aku, spitting bars like a rhythmic haiku
Perhaps it would've been better if you actually faded from existence
That way no one would have to suffer your incestuous film until the end
I've slain enemies more powerful than me, you can't best this Samurai
And despite your name, McFly, it's clear that you're not even close to being fly!
=== Marty McFly: ===
I think staying in the future is making you Mad, Jack
How is it that it took you 50 years to finally go back to the past?
That's heavy, man. I returned to my time period in less than a few days
I still have a girlfriend, while the only one with the hots for you faded away!
You're going to be in deeper shit than Biff and his friends
Watch out, 'cause this battle's getting wilder than the entire Wild West!
My raps are like lightning! I reign supreme when it comes to pop culture fame!
You don't know Jack, Samurai Jack, not even your own name!
=== Samurai Jack: ===
Your rhymes are fouler than the farts of a dragon
Should be considered an unspeakable evil, you teenage has-been
Don't need 1.21 gigawatts to drop powerful raps
I wield a sword crafted by gods, your hoverboard can't compare to that
An almanac's all it takes for your story's history to be rewritten
I'll give you another chance to diss me, if you aren't too chicken!
=== Marty McFly: ===
Nobody calls me chicken! Your foolishness is something I'd agree with Aku!
You're always by yourself, with your only friend being a loud, rude brute!
You'll be knocked back from my disses, man, like I'm the amplifier!
Your flow's slow as your show, while mine's faster than 88 miles per hour!
No need to perform seppuku, 'cause you just got killed by a guy from Hill Valley!
But, hey, at least your rhymes weren't as disappointing as your series finale!
WHO WON?
WHO'S NEXT?
YOU DECIDE!
EPIC-
