Information on the rapper

Master Chief Petty Officer John-117, or simply Master Chief, is a fictional character and protagonist of Microsoft's famous science-fiction video game series, Halo. He is a cyberneticaly-enhanced supersoldier, part of the SPARTAN program, and throughout his journeys, he is assisted by his personal Artificial Intelligence construct, Cortana.

In the year 2525, in the first Halo game, John arrives on an ancient Space-Ring construction, built by an ancient race called the Forerunners, more than one hundred thousand years ago. This Ring, called Halo, was built to destroy and contain a virus called the Flood, which feeds on intelligent life forms. An alliance of alien races called the Covenant wants to re-activate the Halo Ring, like the Forerunners did, for they believe it is a portal to a Religious Journey. They accidentally release the Flood and the virus starts attacking the Humans and the Covenant. On Halo, John has to fight both the Covenant and the Flood to save humanity.

In later games, the battle continues on other Halo-Rings and Earth. John later faces the Didact, a last remaining individual of the Forerunners, who wants to turn humanity into machines, to prevent the Flood from feeding on them. The story still continues.


Stand clear. I'm Master Chief Petty Officer John-117, but you can call me Master Chief. I'm a cybernetically enhanced super-soldier that survived the SPARTAN-II project, but all you need to know is I can kill you in the world of Halo any way I please. My MA5C Individual Combat Weapon System? Ready. A BR55HB SR Battle Rifle with frag grenades? Locked and loaded. How about plasma grenades? Or my hands? Either way, it'll be quick and painless. I also have a sexy A.I. friend, Cortana, who tells me everything I need to know to do my ass kicking. Sure, I always wear this helmet, but don't get it twisted, underneath I'm one sexy super soldier. And yes, I'm also cybernetically enhanced for the bedroom. Wake me, when you need me.

Appearance in the battle (cameo)

Nice Peter vs EpicLLOYD:

Master Chief was hinted to be in Season 2 at the end of the battle.


Verse 1:


Cortana says you're Greek, so why don't you stick these lyrics up your ass?

They built a monument to my sins. You're the soldier they need you to be.

Ain't no way that you can beat me; even my initials spell MC!

While you and your companions were all camping in a canyon,

Took a campaign to your house and showed your queen my plasma cannon!

They should've thrown your rhymes over the cliff because they're sickly.

You will not enjoy this, but it will be over quickly.

Verse 2:

You got a bad case of no shirt there, Fabio Flintstone.

Your whole plan got messed up by a hunchback with Down syndrome!

300 asses need a kicking; give more teabags than Lipton,

So why don't you quit your bitching? My trigger finger's itching!
