BTW, to respond to this earlier post about other-series protagonists, I disagree with some of these takes.
I prefer protagonists that are beatable regularly in general, and moreso that train and don't rely on MacGuffins.
Yusei was a Marty Stu who cheated with his Signer abilities, as was Yusaku with his unfai advantage.
Yugi cheated with Ancient Egyptian artifacts.
Jaden cheated with a pendant, an insider at Industrial Illusions giving him free OP cards that weren't released to the public at large, and Duel Spirits.
This I agree with. Yu-Gi-Oh protagonists have always held onto MacGuffins as secret ingredients to their plot armors and is not uncommon. Yuma is arguably the only exception since he started off the series as very weak (and even then, eventually fell to having a MacGuffin IIRC).
Naruto and Boruto cheat with forbidden powers.
This is where I start to disagree.
Especially with Boruto.
While Naruto was bestowed with "forbidden powers" upon birth via Nine Tails, im not seeing how he cheats with them. Naruto started his series off, again, very weak and was fodder amongst everyone. He had to train in order to master Kurama's power, which for much of the series was treated as something that could prove fatal to him if he could not master it. There's a difference between being handed a power and becoming invincible, and being handed a power you need to actively work towards in order to master. Naruto is the latter.
Boruto is even more an exception here since unlike his dad, Boruto doesn't rely on any special ability. He doesn't have a huge arsenal of power like Naruto did as a Jinchuriki, he is a regular ninja with regular ninja limitations, and thus, can't win every battle just by powering through every opponent. He has to rely more on skill and intelligence than brute force. The only special power he has atm is Karma, which he has no mastery of and doesn't use as his main weapon.
Deku cheats by leeching off an ancient forbidden Quirk.
Again, this is the same as above. Deku needed to train to even use O.F.A. in the first place, and for much of MHA, it would destroy his body when he used it since he could not handle its power yet. On top of that, Deku doesn't win every fight he's in with O.F.A. and like Boruto, use's intelligence and planning to help get out of his situations.
Ichigo cheats by going Hollow.
Agreeing on this. Ichigo...is a mix of everything pretty much.
Avatars cheat with the Avatar State.
Very much disagree on this one too, for the most part.
It's made painfully clear in TLA and LoK that the Avatar State is something only fully realized Avatars are able to access and use
properly after first mastering the elements. The only times its been used as a kind of "Get Out of Jail Free Card" is when Aang randomly went berserk with it.
And even then, the series itself specifies that being killed in the Avatar State is pretty much a permanent end to the Avatar, so it's not some invincible ability.
Hence why Goku, Saitama and BoBobo-bo Bo-bobo are better than Ash, who is better than most of the other main character cheaters.
Because they and the few others TRAIN TO EARN their reality-busting bullshit without MacGuffins, Ash has trained his MacGuffin, while most other anime protagonists cheat via MacGuffin, and are too incompetent, goofy and/or weak without them.
Again, disagreeing with this since some of the people you mentioned above, do in fact, train to earn their powers as well.
And as someone earlier mentioned, what made you think Goku earned Ultra Instinct? Or Super Saiyan God? Or even Super Saiyan? The latter he activated just because Krillin died, and the former he got through outside help, then it magically became a permanent part of Goku's arsenal of powers that led him, somehow, get to Super Saiyan God Blue. At least Vegeta didn't need help to get the form within his repertoire.
