Was Gam really able to defeat those trainers before him? Nidorana is poison and ground type if I remember correctly, you could have taught her mudslap or mudbomb to counter thunder or thunder wave. You are going to tackle a gym so you should have planned a proper strategy. Heck! Even rock tomb can slow down Staryu's speed. Plus, knowing that Nidorana doesn't have any long range attacks and is slow when compared to Staryu, why did you even choose her? No offense but this chapter is absolute crap, plot vice.
I understand the need for character growth but this is not proving that Mc isn't invincible but rather it shows that Mc is a complete idiot contrary to his behavior in the previous chapters. The problem here is that the point you wanted to convey to the readers is poorly portrayed. You could have made him lose normally after all Misty is a gym leader but the decisions made by the Mc are just downright poorly written. This is constructive criticism, take it as you want to. The only reason why I am even bothering myself to list this is that your novel has lots of potentials and your writing style is quite good.
Monster_Paradise:Well, you weren’t paying attention to the previous chapters, I already said that his Pokemon had leveled up during the Rock tunnel. Nidorina is at level 18 just like staryu. This is to prove that the main character isn’t invincible, and that victory plot won’t be on his side all of the time. You must be looking for an invincible Mc, who is probably Op, well that isn’t here. Nidorina is only a poison type and not a ground type.
I can somehow understand both sides. I personally found this fight not very good but not because the Mc lost but because I felt that his strategy was much worse than in his last fight which confused me a bit. but i think that sometimes the opinion of the readers doesn't make sense if they don't try to remain objective. It is sometimes more important whether you think this fight is logical and the Mc acted logically for his character. For example, I personally don't see any problem with the defeat of Alex in my novel, even though half of the comments were about the mistakes that Alex made. If you look at these comments with an open mind and think that they are very subjective, you don't always have to agree with the opinion of your readers. You have to decide for yourself.
