Orochi's Fruit. Imagine having to kill Zoro 8 times, when he has 8 heads to use 8 swords?
Lol get absolutely fucked verse, Zoro with Orochi's Fruit solos everyone not named Mihawk and Smoker in the East Blue.
Hybrid Zoro, if he had 8 heads and still had his arms, could use 10 swords. Just ridiculous.
