(W/A/CA) Aaron Alexovich. Special oneshot from original series artist (and I nvader ZIM character designer) Aaron Alexovich! When Zim, master of fear, gets spooked by Dib, hell do whatever it takes to prove he isnt scared of anything! Or that Dib is scared of something! Or that GIR is scared of everything! ANYWAY! ZIM is the master of fear here, and thats the MOST important!.
