Question 511: A dead Ringer

The following picture is a morphed one, consisting of two personalities originally. It was produced and promulgated on the day of the release of the game Halo 3, morphing the personality __X__, whose head and armaments were used with that of __Y___, whose body was used.
__Y__ can be found at the proverbial bete noire of MIT.
The reason for this atrocious amalgamation given by MIT was that they both share the same name ___Z___.

1) ID XYZ
2) ID what the shared name is between X & Y

ANSWER:


1) X- MASTER CHIEF F HALO
Y- JOHN HARVARD


2) Z- THE NAME JOHN




Under the name John Harvard plays Halo 3, MIT released this prank in September, 07.
The Background:

During the night prior to the release of the heavily advertised Halo 3 video game, MIT hackers transformed the statue of John Harvard into the Master Chief character from the game. In the game, the character's real name is known only as John. John was wearing the signature helmet from the game and was also holding a gun from the game. The hack was removed by around 8am.

The back of John's MJOLNIR helmet read "Master Chief in Training" and his right shoulder had a Beaver emblem. The Assult Rifle was labelled as having a remaining bullet count of 2E and said "Eng Div" on the butt of the rifle
