Mark II... it's something Otacon came up with for a little gadget that helps me in my time... A robot that can hold items and shock people, as well as scout out for enemies... he can do a lot of useful things.

It actually stands for Metal Gear Mk II, but I just call it the Mk II for short...


[...] It's a little weird to explain anymore unless you can understand all that, so, uh... Just a machine name.
