You guys should get ready for Imu being used to Hype Zoro very soon,
He obviously won't Defeat her, but He will prove himself to be a Nightmarish Opponent,
We saw Zoro vs Shark (Hody) Clash in Sea Arc,
Followed by Zoro vs Tiger (Fujitora) Clash in Land Arc,
Followed by Zoro vs Dragon (Kaidou) Clash in Sky Arc,
Next is Zoro vs Devil (Imu) Clash in Hell Arc,
He gave both Hody & Kaidou a Permanant Scar, while Fujitora only got a Warning Attack (Cuz He wasn't Arc's Main Villain),
Meaning regardless if Zoro gives Imu a Scar (Like Hody/Kaidou) or only force her to turn Defensive (Like Fujitora), both scenarios indicate that Zoro is soon gonna be able to do what all these Top Tiers failed to do combined. (Threaten Imu's Life)
