Your story is very similar to this fanfic: Fairy Tail: Get A Bigmom Template At The Start. Well at least the first few chapters are pretty much the same if you put aside the fact that the MC is different. (Google translate)

I know it's difficult to create a story, but there's a lot of difference between a fanfic with an original and creative plot (even if it's bad) and one where the original work is blatantly copied (as in this case). It's okay to support novice writers but not those who just copy and paste. (Google translate)

Seriously? Having the mc join the straw hats is already a bad point for this story; but on top of that the 'author' copies the original dialogues letter by letter? This is absurd. Many Chinese fanfics that follow this same theme do the same, and each of them can be summed up in a single word: Rubbish! (Google translate)

Kushina in this ff:

My only problem is the performance of the mc. He mimics Black's style due to his identity as Tenryubito, but was it necessary to mimic Bigmom's traits even when their experiences are totally different? I just hope that the mc has his own personality and not an amalgamation of various characters. (Google translate)

I agree. I think it's not an exaggeration to say that I understand an MTL novel better than this ff. (Google translate)

Not just Pokemon fics, most Chinese fanfics pretty much destroy the essence of the original story. The authors change the background of the story, the personalities of the characters, the power levels and so on. (Although in many Webnovel fanfics this also happens) And they also like to transform worlds like One Piece, Fairy Tail, Naruto and so on into something that looks more like a Wuxia/Xianxia story. (Google translate)

Thanks for the chapter!!

I know, as the author said this ff is wish-fulfilment; but what I mean is that in most fanfics the MCs let Orochimaru live. I read one where the MC was a Saiyan but Orochimaru still used his DNA to make clones and stuff like that. It's probably because I'm a bit paranoid when it comes to scientists. (Google translate)

Thanks for the chapter! This is a personal opinion: I don't like it very much when the mc of any naruto fanfic lets Orichimaru live when he has the chance to kill him. Characters like Orochimaru are very insidious and difficult to predict. I know that as a scientist he is very valuable but unless the mc can control him I think getting rid of him is the best option. For example, the final sentence of the chapter is like some kind of 'Flag' that foreshadows some kind of event that will negatively affect the mc or his loved ones. (Google translate)

The forced plots have already begun! I mean, just as the mc sends clones all over the world in search of his clan members, why doesn't he think of leaving several clones in the village to supervise when he's not around? This situation with Kushina was easily avoided but due to the 'plot' it ended up happening just like in the original story. Hopefully the author creates better plot twists in the future and not something as clichéd as this. Thanks for the chapter! (Google translate)

Are you fckng serious? Because if so, I don't want to imagine what kind of decisions you will make in the future. (Google translate)

I was going to start reading the first chapter but decided to check the reviews first. Thanks for leaving this review!! I personally detest hypocritical protagonists and those with a 'Japanese' mentality; they are really annoying. (Google translate)

The truth is I don't know if it's misinformation or not because I didn't read the novel up to that point, but several readers affirm that it happened.

This is from one of the reviews of his other fanfic, Endless Path. So don't be surprised if something similar happens in this ff. (Google translate)

I only hope that in the next chapters we will see a better development of the mc, because until now he has not proven to be the genius of his past life. I mean, during this 'conflict' with the Straw Hats he wasn't very smart at all., from the beginning it was obvious that luffy and the others weren't going to have a good impression of him. Thanks for the chapter! (Google translate)

Well, Mito put a seal on the mc... basically the mc can't think or do anything that could harm Kushina, he can never leave her and if the time comes he must give his life for her. Basically a slave. If you want to see other opinions read the comments of chapter 6. (Google translate)

The original name of the story is 'A Badgers Champion' by OrionB15. It has 51 chapters but the author has not updated since August of last year. (Google translate)

No, that's not what I mean. The mc is like a babysitter for the alliance, he solves many of their problems. What doesn't make sense is that the mc can solve those problems before they get much more chaotic, but one way or another he always waits until the end to intervene. (Google translate)

This fanfic is extremely boring. It's basically a bad retelling of the original story, only there's a 'mc' who is supposed to help Luffy but in the end it doesn't change anything. (Google translate)
