Sonic and the others raced through until they stopped seeing Infinite, Tempest and a mind controlled Twilight.
Mane 5: TWILIGHT!!!
Sonic: NOOOOOOO!
Infinite: So much for the princess of friendship.
Infinite glares at Sonic, who is really made at him. Everyone looked at him as his eyes went white and his fur and muzzle went black as his quilts were up like his super form.
Sonic: Now dark HOW DARE YOU YOU BASTARDS!!!
Classic looked at his modern counterpart. Shadow couldn’t believe what he was seeing as the rest gasp in shocked. Sonic charged at Infinite but avoided him as he hit evil Twilight causing her to gasp in horror. Twilight’s armour of the Storm King was gone as her eyes went back to normal.
Twilight: Wh-what happened? looks up to see Dark Sonic fighting Infinite gasps SONIC!
Sonic turned to her as he was surprised.
Dark Sonic: Twi……light?
Twilight: It’s alright Sonic. I’m back now.
Sonic turned back to his normal form and hugged as their friends smiled at them. And now they turn to Infinite and Tempest.
Tempest: growls The next time we meet……
Infinite: You would all be too late.
The two laughed evilly as they soon disappeared alone with the Storm Creatures and Eggman’s robots.
