Bad, where is your Usopp Golden Pound?

But dont worry you have Zoro Lion's Song to beat Monster Chopper with another Princess Vivi 5* Level 72+ as Captain.

^^

I didn't know when I evolved my ussop and what other units should be apart of the ls zoro and vivi?

you should also take diable jambe sanji with you for the fourth stage (use his special). The others should be your best quicks with the highest attack. Also not Level 72+ Vivi, but 73+

Mystogan can you explain why we need a Level 73+ Princess Vivi 5* and not a Level 72+ Princess Vivi 5* to beat Monster Chopper 40 Stamina with another Zoro Lion's Song as Captain?
A friend of mine says that serves a Level 72+ Princess Vivi 5*.

^^

As there are many questions about Vivi's Level i will explain it in detail:
As we know chopper attacks all 3 turns,so many question why they need a specific level.
Moster chopper attacks with 10072 damage each three turns. With lion song the damage would be reduced to 2014,4 damage. Vivi on level 72 only heals 2005hp. So if the situation comes that chopper hits you with his attack and after the attack he drops under 20% health, he will attack with his special in the next turn, which means you need a vivi that can heal you in one turn to full hp. Back to the top vivi 72 only heals 2005 so you will need a vivi level 73 or higher to heal back to full hp.
(Vivi level 73 should heal about 2020hp)

Beautiful explanation just that I was looking thx Mystogan.
^^

thx Ciro.
I just want to add a alternative version for those, who won't be able to bring her to level 73 in time:
As I metioned before, the situation can only take place one time in the fight. So if you see monster chopper is getting near the 20% mark, just start saving up some meat (so much that you can compensate the lack of vivi's recovery). It will take longer but you will be able to survive the hit. 
Improtant: This is only for those with a Vivi that can heal minimum 1848hp
because monster chopper will hit you under 20% every turn with 9240 damage, which is reduced 1848 damage

Couldn't you bridge this time with using Ussop? Or would Chopper attacke even Ussop use his special...
It was just an idea from me, but I think it doesn't work (otherwise this would be already known)

@masi576
Yeah it works using usopp. But using ussop the whole time will lenghten the fight more than just saving a piece of meat for a few turns, so I would prefer the meat version. But the best option is having a vivi 73+.
