If a character struggles for 12 hours, and just on the very last part of the fight he decides to show a power that he has been hidding for hundreds of chapters and by some coincidence of destiny that transformation is precisely what he needs to beat this specific villain , that is a classic asspull right there the author just did, and this is what we are arguing about here. Gear's transformations make absolutely no sense and Oda just keeps pilling them over everytime Luffy struggles for HOURS with the same stupid flashback saying he fought monsters in the wild.
Oda just keeps adding new transformations because he knows people get exited over them, thats why Akira Toriyama didnt stop adding new hair styles for his super sayians up until now. Remenber when there was no need for stupid transformations in one piece? yet you could clearly see the characters getting stronger? That was much better.
BTW, "dumb" is not a bad word, soo chill out with your language filter captain america.
