That is all you Runners are. Following those with the charisma or alleged intelligence to lead you around. Robbie Boy, Zero, M, and Strahm fit the bill for the most part. Thus there is a small army of Runners emulating them. Why do I bring this up? Because this is the only reason any Proxy should really fear Zero. Runners who believe in Zero's ideals and are tracking down other Runners and Proxies. Amusingly enough Zero seems to have absolutely no idea that they exist. Oh well. If he did know, he would just kill them all anyway. Maybe. His body count is less than impressive, and his victories in straight up combat are not very intimidating.
Since I assume Zero is watching this blog, and I LOVE watching people become conflicted... Zero, if you were REALLY dealing damage to Him, or His servants, why did He stop Rika from killing you? The answer: You are dealing more damage to Runners than any proxy ever before has. You are their Hero and quasi-messiah, and now you are hunting them down, trying to kill them for simply being victims of a horrific monster. The average Proxy is a mindless puppet, a faceless goon, or an obviously evil psychopath. Redlight, Rika, Conaghan, Alder, Al(x)ne, ME... We were hated from the very beginning. But you. You were loved and respected. Now just another tool for Him. You have hurt them in ways WE never could have. And I thank you for it. Zero, the Greatest Proxy who ever lived.
