Shadow is a black and red hedgehog with a horrible past the only thing he was created for was to destroy the humans on the A.R.K , Maria ,the grand daughter of Proffesor Gerald Robotnik dies due to the g.
u.n men , as a result the Doctor only wants revenge creating Shadow, soon after being re-awakend by Eggman and fighting in the a.r.k they soon learn what shadow'
s motive was all along so when
Amy convinces shadow ( sa2b version) that he should
help and after a little memory with Maria to
help boost things up shadow teams up with Sonic to
help the humans save
earth I personally believe shadow is waayyy better than sonic since he would give up anything to
help his friends and even though he's tough on the outside he's really kind and gentle in the indside so there's my definition of shadow the hedgehog (ps.remember kids he's mine ;D)
