[JagermanXcell]

The Ultimate Co-Op weapon Human Slingshot from MGS: Peace Walker.

What can I say, I've always wanted to travel places quick while saluting and transforming into a rainbow man bullet of destruction and fireworks.

Tough one.
The Stealth Cruiser from FTL: Completed the game with her and have a soft spot for stealth ships.
Baneblade Superheavy Tank from Warhammer 40k: Despite the impracticality of the thing, 11 barrels of Hell is easy enough to end an argument.
The Merc ship Riddick steals at the beginning of Chronicles of Riddick: I love the design.

Spoiler: REAPER MORPH!

A fully moddable body with lots of space for weapons and lots of armour.
