Master Chief

The protagonist from the Halo Series by Bungie. He could totally kick you ass. And you know it.

Master Chief kicked the Flood's ASS in Halo 1, 2, and 3.

Master Chief is the name of the rank that John is, his spartan number is 117. He is the playable character in both Halo: Combat Evolved and Halo 2. Hes a badass character, hes so badass that he just has to walk on screen and you can feel the badassness radiating from his badass aura of badassness. He doesn't need to walk on screen and snap some necks or crack some skulls to look like a badass, he just walks on screen. Okay, enough of my undying love for the most badass video game character.

Master Chief is a badass.

Master Chief

If you're playing Xbox Live, and you just so happen to come across someone with the name "Master Chief," you've been blessed.
Now, there are plenty of people that go under that name and then add excrutiatingly long numbers, but if you see the original "Master Chief," consider yourself a child of good luck.

I was playing Halo 2 yesterday and I met the original Master Chief, so I think I'll go gambling today.
