Zoro Clashed with Shark (Hody), followed by Tiger (Fujitora), followed by Dragon (Kaidou), so He is 100% gonna Clash with OP Devil & OP God,
And seeing how He performed against those, i'm certain that Imu is gonna be super Shocked by Zoro's Power,
You can even notice that Zoro ended up Underwater against Hody (He sank the Place) but He Blitzed him,
He also ended up caught by Fujitora's Gravity, but He Countered it,
And also ended up in the middle of Kaidou's Tornado but He Countered it,
So Zoro will end up Caught in Imu's Power whatever it is, and He will show him why such thing won't Stop him,
We might see Upgraded Version of Daibutsu Giri & it's gonna baffle Imu.
