If anyone as anything they want to add to this please tell. Still doesn't make sense why Shadow ends up on a field and is looking at a city.
Then in the Shadow the Hedgehog game if you wait for a long time during the final fight with black doom where your Super Shadow/ Hyper Shadow (whichever you prefer) you'll hear Robotnik say that the Shadow your playing as is the one from Adventure 2 and he says that when Shadow fell at the end and was thought to have died, that he sent one of his robots to catch and save Shadow. Metal Sonic could use Chaos Control because he copied Shadow's data. But if he's a robot then that doesn't make sense. Now I think in Heroes they get the concept of clone and robot mixed up but if you listen to rouge I think she means that the Shadow in that one is a clone which would make sense why he can use Chaos Control. Then in Heroes if you beat Team Dark, Rouge finds all the pods with Shadows in them. The multitude of fake Chaos Emeralds and Sonics intense anger allowed him to. Why Sonic can I don't know but he just can. Shadow, Sonic, and the Biolizard can use the Chaos Control. It was designed by Gerald Robotnik to only work with Shadow, but.
(too much free time) The Shadow in Adventure 2 is the real deal. Chaos Control is the main ability of Shadow the Hedgehog, which mainly comes in the form of energy generated by Chaos Emeralds Although Shadow the Hedgehog is the first user of Chaos Control in Sonic Adventure 2, the oldest user of Chaos Control is Black Doom, having used it to warp the Sky Troops into the Glyphic Canyon.
