This is an old one, but it's one of my favorites so I will reup it here!

if you care wtf is going on: Their world was invaded by computer virus spirit things (a thing i made up which I call machinae because i'm clever unoriginal) and Metal (the fellow on the right) got possessed by one. His 'soul' got sealed in the Machinae's dimension while the spirit pranced around in his nanite body (god what a douchebag) and it took RK fOrEvEr to hunt Metal down (not for lack of trying), but he eventually did! and then it seemed the only feasible way to get Metal out of that dimension was for RK to take Metal's data into his own body. Apparently that isn't a very good time. RK proceeded to keel over and MS2 had to drag his ass back home.
