Sonic is hit hard by his metal counterpart... or would have been anyway, had he not anticipated his arrival and sped out of the way. Although it was a bit close for comfort there with the timing.
Standing back up a ways from Metal he'd smirk at the robot's actions and throw some sass back at him.
Metal, buddy, it's been almost an entire generation since I last turned you into scrap. I was starting to miss getting to kick your butt. Nice catchphrase you got there, but you should really try and copy something more fitting. Oh, how about this? "I'm a dumb robot that wants to be trashed by Sonic the Hedgehog." I think that'd work out better for ya, don't you?
Sonic would casually pace back and forth while giving his response. When finished, he would begin charging a Super Peel Out.
It's looking like nothing but a bad future is waiting for you at the end of this Metal. Hope you're a bit better than last time.
With that, he'd burst from his position with speed the untrained eye couldn't process. For Metal, it would just be a warm up for when things really got heated up. Running around the catwalk, if Metal didn't follow, he'd circle around and jump to homing attack the robot.
