there is mecha sonic who is kindove like metal sonic
nope
They only appear in sonic underground
If you mean by any other type of sonic games,yes in sonic rival 2
No. Well it is not proven that Sonic did have any other siblings besides Sonia and Manic who were later on discarded by the Sonic team along with Sally Alicia Acorn, Antoine,and that walrus guy plus a number of robots including the chicken guy and his friend who were later on edited on to Deco and Boco (Sonic X) who were edited on to this crazy light bulb guy(Sonic Unleashed).
Yes I'm not saying hype but you can unlock other chracters besides sonic and tails
Shadow,Rouge,Cream,Eggman,Eggman's 2 Robots,and 3 other Characters.
yes, my brother has completed the whole game. To get metal sonic you have to get every single emblem and finsh all the other story modes
Shadow is not playable, and no other Sonic characters besides Sonic himself are.
Metal sonic doesn't love shadow he only has his mind set on Amy. But shadow loves metal sonic after his dear sonic was killed along with egg man when the egg breaker self destructed. Shadow loves metal soic because he reminds shadow of his dear sonic metal sonic finally gave up and got together with shadow they are know mown as metal sonadow.
In the first one...no but in the the second one he has alternate outfits
to fight metal sonic in sonic heroes, you have to beat all of the other team's stories, and once that is done, in story select (when you choose the team you want to play as in story mode) keep on going right and you'll see a team called LAST with metal sonic on it. (this is kinda hard.)
Metal Overlord, Metal Sonic after having absorbed the energy of Chaos, Shadow and some other people.Although personally, That last answer did give me the giggles.
