If I remember correctly, it is Knuckles who can climb, and not Sonic.

Anyway, Zero could use the arena to his "advantage" but anyone who has played a Sonic game knows that complex changing and rotating environments are where Sonic is at his best. Sonic's overwhelming speed and agility would surely catch Zero off-guard. As !K_A! stated before, most of Sonic's enemies are robotic so he clearly has the strength to bust Zero open with ease. And if Zero even gave Sonic the chance to go Super Sonic or even Hyper Sonic, he'd be totally fucked.
