I donât think itâs author favoritism, or at least.just that..Levi, Erza.and  Kenpachi especially, are fan favorites. And itâs pretty much considered too âriskyâ to kill off fan favorites as the magazines that contain these mangas lose money because fans drop/lose.interest in the manga because their favorite character has diedâŚSo I wouldnât just blame the mangakas..It could also be the editors pressuring mangakas to focus more on certain charas cos of their popularity.
I have serious doubts about how much that applies to Levi. While itâs true that fan popularity saved Sasha Braus, who was the most popular character in the entire manga? More popular than Levi himself? Iâll tell you who, the Colossal Titan. That was an icon, the biggest symbol of power and futility in the series. That did not stop Isayama from killing him off--nor was he prevented from killing off Erwin Smith, another fan favorite.
Hereâs an easy way to tell if Isayama in particular is favoring someone. One of the biggest themes in the story is how, when set up against impossible, unstoppable foes like the Titans and Titan Shifters, no amount of bravery can hold up forever and youâre not guaranteed a glorious, admirable death--even if youâre a seasoned, hard veteran, the death you get may involve you screaming for help and being torn to pieces, be too scared to act properly, or just plain having a very unglorious death. It happened to Squad Levi one by one, and it even happened to Mike Zacharias, probably the most skilled human soldier there was after Levi. The sheer horror of their fates made holding up their dignity a very unrealistic concept. Again, this applies even to the Colossal Titan.
Now tell me--can you see a death like that happening to the heroes? Levi in particular? Or Mikasa? You canât, can you? Hell, when Erwin died, he went out fighting no matter how futile it was, and gracefully accepted his own death. Even when Armin died, he faced a very, very painful death via being steam-blasted with enough heat to burn his flesh off with more dignity than pretty much anyone in the series had mustered, and pain tolerance was never his strong suit.
Thatâs how you know. The unclean, unsightly or undignifying fates donât apply to the heroes Isayama likes, only the villains or non-villain characters he doesnât care for.
Now, I canât say when it comes to Kubo. I know Kenpachi Zaraki was a massive fan favorite (for reasons I canât fucking fathom, seriously I donât get it), and that may have prevented Kenpachi from getting the death he very much had coming. But nontheless, that doesnât excuse what happened. Kenpachi could easily have been put up against opponents where his powers would have been more believable--despite how stupid his fight with Nnoitra Gilga was, that was indeed what Kubo had in mind. He matched the bladed direct combat specialist with another bladed direct combat specialist, as against any of the other Espada Kenpachi wouldâve been pretty damn helpless. Gremmy Thorneaux was not an opponent Kenpachi could stand against. Any number of the Sternritter--there were 27 of them--wouldâve made a better match against Kenpachi. Fan favoritism may have been what assured Kenpachi staying alive, but it is not what wrote the fight scenes and battle match-ups. If Kubo wasnât going to keep Kenpachi in fights he could realistically win, he should instead have given him a realistic loss. Neither happened, which is why I think itâs author favoritism.
And Erza? Not even arguing that one. Erzaâs fan popularity doesnât even begin to excuse the way sheâs been played since Tenrou--thatâs all Mashima.
