OK,
I have just been shouted at on messenger because of the above post.
A self-defeating paradox occurs when a future event affects a past event to render itself invalid. For example if i go back and shoot my grandad then i won;t exist so cannot shoot him!!
K9 is an Ontological paradox which basically a time loop.
K9 was designed around an inherited circuit board. The circuit board was from K9. There is no evidence of originality or anything. K9's existence is dependent solely on his existence.
