We all know that Wily BUILT Zero, but did he design him? There are many evidences to support the fact that he was designed by Light, and not Wily.
1. In RM7, Forte steals some things from Light\'s lab, which possibly could have contained plans for Zero. Notice that soon after 8, in power fighters, Wily shows the plans. The time between these two events is not very long and could have a significance.
2. Zero\'s design is very similar to X\'s. Their personalities are very similar, but Zero is more inclined to fight because of his rewritten program segments.
3. Zero has \"Wily seizures\" at odd times. When a computer has a hardware fault or the OS malfunctions, it blue-screens and crashes. This is similar to what happens to Zero. When Light possibly created Zero, he could have encrypted portions of the code to prevent Wily from hacking it. Wily, thinking these segments were part of personality or movement drivers, did not notice these segments of code. Thus, when his system starts up, the Wily code executes and he is very violent. Eventually, his system runs over the encrypted code and executes it, causing a system conflict. The Light portions try to overwrite the Wily portions and cause Zero to lose controll. The Zero we see in his past memories was under control of Wily\'s programming, while the Zero we see throughout the series is under the original Light programming. His flashbacks are instructions left by Wily that are barely there.
4. Light knows Zero. When Zero appoaches certain capsules, Light addresses Zero by name and even gives him armor on one occasion. How could this happen if Light had not designed Zero in the first place.
5. There is known to be an anomaly in Zero\'s system. His ending in X6 could very well be a flashback. 100 years passes between the original and X series, so this makes sense as to why X7 exists. The Zero series has done the same thing as the X series did. We will most likely never see a crossover between the two series.

There are unanswered questions. I have answers that might fit.
