Zoroark is the mysterious Pseudo Legendary Illusion Pokemon. This dark type pokemon is as cunning as it is deceptive.
Illusions = Chameleon Arch?Edit
Zoroark's speciality is the ability to take on the appearance of something else, whilst its capabilities remain fundamentally unchanged. This deception is entirely undectable. The transformation happens on what is essentially the cellular level. The entire genetic structure of a Zoroark is presumably transformed!
Now, we know time lords have a similar means of disguising themselves, via a Chameleon Arch; a device which rewrites the entirety of a Time Lord's DNA structure, creating the perfect illusion. It's quite clear that Zoroark's illusion ability is some sort of advanced variant on the technology of The Chameleon Arch.
Furthermore physical similarities may be seen between the two characters. Zoroark, while clearly a later regeneration still retains the shoulder pads, stance, and intellgience that so defined The Rani.
