Lmao HELL NO. In one piece they do shit on their own most of the times. It's not nakama power if they are fighting enemies together. It's nakama power when *****s are fighting 1 enemy then saying "with the power of friendship WE WILL WIN" then they do.
Check it. Re-watch one piece and you will see that them *****s always fight by themselves. I rarely see one of the important chars fight 2ormore v 1 person.
We must be watching 2 different series.
I can give soooo many examples:
I could go on and on and on and on. And then I could give you about 5 fights (I doubt they even did a 2 or more v 1 person more than 3 times; but lets use 5 as an example, even though we know it's not that high) out of 636 episodes where they fought together. Then I could also show you that nowhere did they rely on nakama power to get through their struggles.
Also, don't misunderstand the meaning of nakama power.. It means "we're friends so lets use our imaginary friendship strength to beat an opponent". Nowhere in OnePiece has that ever happened nor will it ever happen.
