User blog comment:TheRealD/What's even the point of Mansherry at this point?/@comment-10543621-20150124052419

She'll be useful to patch everyone up after the fight is over that's for sure. To me, what I gather from the reveal of Mansherry's powers is Sunny crew is probably not gonna be back on Dressrossa at all even after everything is over, including Doffy being defeated.

We all know Luffy always gets completed messed up after he finishes his boss battle. He's often on the verge of death. With an enemy as powerful as Doffy, that's almost certainly going to happen. Although Law is present as well, but I imagine they're both gonna be completely screwed over and near dead after Doffy is brought down. Chopper being still on Sunny, and no where near to treat their injuries would mean that Mansherry would be an extremely convenient person to have around.

That's all I see from this. Probably Luffy and Law are close to dying, SHs are desperate, calling out for Chopper to no avail since he's not around, an in comes Mansherry to save the day.
