Since Time Travel means automatically that a character can exists a billion times and even more just by going one millisecond back in time and taking the past version with you. Time Travel does not work at all in any points of being logical, especially in the Universe of Sonic the Hedgehog. (Warning, the following words are now only the opinion of the Administrator).
Silver the Hedgehog is a character who came from the “Future” and even though its confirmed by SEGA that he indeed is from the future, it is very unlikely that this could work.Even though Sonic the Hedgehog 2006 isnt canon when it does come to its plot or Silver’s and Blaze’s origin, it has some elements which do lead into some character development, for example that Shadow the Hedgehog and Omega did start now to work for GUN.He did not die in Sonic Adventure 2 he was saved by Eggman and recovered. The Shadow who appeared for the first time in Sonic Adventure 2 is the same Shadow who also did show up in all other Sonic Games.What we know though is that all non-human characters become much faster mature than humans.
Its unknown at what age the character are considered to be mature enough to be viewed as adult. Keep in Mind though that Sonic and his Friends are non-human, they have a complete different age system and play by other rules than humans do. To the Point of Sonic Adventure, all the characters aged a bit.It has some differences though compared to the versions before, like you can play Sonic the Hedgehog 3 levels with Knuckles, or use Tails in the Levels of Sonic & Knuckles. Sonic the Hedgehog 3 and Knuckles is a game which contains Sonic the Hedgehog 3 and Sonic & Knuckles.In the original version you see also at the end of the game an image that shows up with Tails on it saying “See You Next Game” as reference to Sonic the Hedgehog 2. More evidence is manifested when you take note that the idle and some running sprites are the same as Sonic 1 in addition, the spin dash took a different form. In Fact Sonic CD’s concepts and its project already started directly after Sonic the Hedgehog 1, and was planned to be released before Sonic the Hedgehog 2, but it was delayed. Some People consider Sonic the Hedgehog 2 being the second game in the Main Timeline, but that is incorrect.The 7th Chaos Emerald was later discovered in Sonic the Hedgehog 2. Neither Classic Sonic nor Robotnik knew about the 7th Chaos Emerald in Sonic the Hedgehog 1.There are up to 150 different cards to earn each has a different exciting function.

All characters perform Homing Attack and Spin Dash missions to collect items to increase their level. Sonic Rivals 2 has up to eight characters to choose from, including five from the previous game and three new characters. From here the fight for Chaos Emeralds stones between the two forces begins. That’s why the Silver the Hedgehog and Espio realized their mission – to save the world, the only way they could do that was to find the seven Chaos Emeralds to lock the beast “Ifrit”. At the same time, on another planet being destroyed by “Ifrit”, people are very worried about this issue. To complete his plan, Eggman Nega secretly hired Rouge the Bat to continue searching for the remaining six Chaos Emeralds. However, to take “Ifrit” into the current world, it takes seven Chaos Emeralds. Along with the greed to dominate the world, steal the beast, Eggman Nega has once again disguised himself as a doctor to facilitate the theft of the Chaos Emeralds. Since ancient times, people have propagated that if someone owns the beast “Ifit” will become invincible.
