Nazo is a half real character. The reason why is because he was first discovered in Japan and then released to the United States but he has nothing to do with Sonic the Hedgehog at all. They did make videos of him. You can find the following three at the Related Link.

According to the Sonic Team, Nazo the Hedgehog was intended to play a large role in Sonic X (the TV series) season 4. For why he was cut is unknown. There are 2 fanfics (fan fictions) of Nazo the Hedgehog entitled "The Power of Nazo" and "Nazo Unleashed", of which both were created by the same person. These, however are, of course, fan-made, and are possibly untrue. The only reason Nazo was discovered is because of the picture Nazo.jpg. This was implied as Nazo's given name. This is questionable because "nazo" in Japanese means "mystery". Nazo, right now remains a "nazo" until Sonic Team decides to revive him. That will only happen if the popularity of Nazo rises and demand for information or a game introducing him would convince the developers. The problem is: How do we get the attention in order to make them do so? There are rumors that Nazo is a fan character, which are completely untrue. As stated previously, he was supposed to be a main character in Sonic X. There are rumors that Nazo was cut because developers couldn't think up a storyline for him.
nazo is an ultimate life form so like shadow is age-less
