sonic cant turn into super sonic because they are two different charaters
Metal Sonic is not a platable character by conventional means. The only unlockab;e character is Super Sonic. However, a version of Metal seen in the opening (as he transforms into a rocket) has been made available through hacking the arcade machine. It is important to note that this is the only way that it is possible to hack the game- the Gems version does not have all the leftover data from unused characters. This version of Metal is called Model 27 or Rocketmetal. As for the true Metal, it is also possible through the methods, although Rocket is the one that usually gets the credit.
