I don't care what power he has there is no feasible way gajeel could ever even get the interest of kenpachi. Furthermore only zeref max power (and it is really iffy), possibly acnologia true form and natsu end that 7 flame thing could even damage kenpachi and no one from the cast there except ichigo could defeat him.

I think it's OOC of Nami to attack Hitsugaya, considering her actions in Punk Hazard. She has a sore spot for children and would be the last member of the Starw Hats to attack a child unless it's for comedy purpose. She would eventually if her crew is in a risk, but she wouldn't be the first one to volunteer.

So when are you going to do it?

Why Orihime not helping with the healing. She's there with them, it's not like her to not help.

I think oh shit would we the right words for the end of the chapter

SHIRO - CHAAAAAN
HE SHOWED UP, HE SHOWED UP, MY HITSUGAYA TAICHOU SHOWED UP I'M SOOOOO HAPPPPYYYYY

A great story, but you're not giving the characters their proper strength. An example of this would be Ace and Natsu's fight. If it was by skill and fighting ability, Ace would kick Natsu's ass all around the New World. Same with Erza and Shanks. Shanks is a Younko for a reason-meaning he's one of the four strongest people in the world. Erza wouldn't be that strong. My last example would be Angel knocking Luffy out. I know for a fact that that won't happen. Ever. If Lucy could defeat Angel, then it wouldn't take two people to defeat her. Overall angel is one of the weakest villains in Fairy Tail.
But overall, I love the whole idea and I love how you wrote it besides the part that I wrote about above c:

aww...Kenpachi didn't even take off his eyepatch.

(OPINION) ...feels bland, you just throw the characters into the place with little entrance, barely any explaination on how they got there, they act way to casual when each group meets each other, the 'evil' person is there for two seconds and you throw the group into an instant fight seconds after the start of the second chapter and 'evil person' introduction. the plot doesn't make any sense and i feel like this wasn't thought through enough and it doesn't have the tone, your spelling and grammer is alright and your paragraph spacing is ok but thats all thats going for it.

interesting start

ME GUSTA INTERESADO!

That's not a real sentence by the way, but this looks very interesting! And its completed too ! I look forward to this!

Well the fight it self was quite interesting except the end when they suddenlu got up and defeated Shanks and Mihawk... That just seems so far fetched! Especially if they were hurt that badly! I kinda expected at least 2 vs 1 or something like that since those two were really something that you don't want to mess with (no matter how strong you think you are) when they're in a bad mood! It felt more like their true will just didn't allow them to continue fighting at "full" strengt and just allowed Erza and Ichigo to win...

don't you think that putting them against Shanks and Mihawk at this stage is kinda extreme (unless you plan to make them quite weak...)?

Yet another logia user that fell without a real fight... i mean he was stabed like he was a mere weakling witch we all now he's not supposed to be :/

Umm the fight was going on quite well except that it ended in a sec... i mean what kind of fight ends like that ? Not to mention how the hell was Natsu even able to hit a logia user witouth haki or sea prism stones? Natsus attacks, not only shouldn't have done any damage but had to went through Ace as well...
