The Dark Pickle used to be Pickleboy's imaginary self-image, how he would envision himself fighting crime. Pickleboy was immensely surprised when the Dark Pickle showed up in reality. The truth of the matter is that at the end of season 1, Doctor Z, the master criminal, cloned Pickleboy with a sample of the hero's DNA and created the Dark Pickle, who is much more effective than his original counterpart. The Dark Pickle starts out as evil and then changes to good after some soul searching and a brief romantic encounter with the Amazing Megan. The Dark Pickle and Pickleboy share a telepathic link which becomes active in their dream states. That is how The Dark Pickle came to design himself the way Pickleboy envisioned himself.
