Tracker The Hedgehog - Alternative Shadow

Like with Speed, Tracker's DNA was altered. He is completely blind thanks to the scars on his face he got in a fight with Xavier. Yet, he has some kind of transformation which works much like Dark Super Sonic and increases his remaining senses about the 3x of the normal. Demon Tracker, as this form is called, is a destructive monster, who'd even go far enough to kill his own friends. The aliens that attacked their homeworld are called "Begoman" and are a Warrior-Race, who cause massive destruction all over the universe. Most of Tracker's and Speed's friends (including Amelie, Ember, Brace, Xavier and Swift; Swift managed it to escape somehow) were killed or enslaved when the Begoman attacked. Due his altered DNA, Tracker has the ability to control Nuclear Energies, which is also the reason behind his Demon Form.
