Panel 1: DIB is in a techy science lab of SCIENCE(!) belonging to PROFESSOR MEMBRANE; it’s clearly a place he’s definitely not supposed to be. The main scienc-y thing that he stands next to is a large techy pod.
DIB (1): If the calculations I borrowed from dad are correct…
DIB (2): …Zim being his own worst enemy combined with whatever it is from my brain that drives me to save humanity in spite of itself…
DIB (3): …should give me a Zim clone that will defeat him for good.
Panel 2: DIB pulls a lever.
Panel 3: A lot of steam and light pours from the techy pod.
Panel 4: The pod opens up and a cloud of dramatic smoke covers the floor. Inside the pod is a copy of ZIM, but with your traditional goatee and mustache. He also has a large smile on his face.
DIB: (Minimized) Good Zim?
Panel 5: MIZ is outside the pod and looking toward DIB. His smile has turned sinister.
DIB (1): You don’t look very good.
MIZ (1): That’s because I’m not.
DIB (2): I’ve created an evil twin? But Zim’s already evil!
MIZ (2): Exactly.
Panel 6: Close-up on MIZ.
MIZ: I’m his evil-er twin.
