The more I look at the sequence of this fight the more it feely like your typical, classic Dragonball back-and-forth where you get one side hyped up in one chapter only for the return ball to completely squash the opponent in the next. It is so apparent and on the nose that I cannot even tell anymore if Nakaba is doing that on purpose or just falling into the typical shounen trap because that shit sells.
Could all be a red herring but the entire lore as well as concrete, measureable feats for Lancelot that aren't just hype and vibes are so all over the place that Nakaba makes it feel strangely non-committed? I don't know how to put it into words better. For example, you have these ancient chaos beings who should know what they are talking about when it comes to the capabilities of Chaos, Cath hypes Lancelot as so strong that he couldn't take him even with Arthur's portion of it (take that statement as you will), the LotL says him handling her infinite magic makes him the strongest or whatever, bla bla. It's all lore and hype and then Lancelot steamrolls but once he faces someone of Sins-level or their general ballpark Lance somehow falters or struggles and seems inconsistent and the reasoning for that is never given as something clear and defined but rather left as guess-work for the audience to squabble about because, might just be that physical strength isn't his forte, right? It's all thanks to the magic amp, bla bla. Or now he is hyped up as this destroyer of worlds who first dominates Zeldris and makes him utter statement like being stronger than the old DK or almost being unable to react to Shining Road and this chapter Lance slowly falls apart and yet again we are left within our own headspaces figuring out the reasons with our own headcanons...
And I mean, don't get me wrong, that's probably how it should be. If an author explains away every little detail it gets super dull, braindead and boring as all hell. But in Lancelot's case I feel like it's a tad too much of the opposite, Nakaba never seems to want to commit to one canon explanation for anything regarding who and what he is and what he is truly capable of, how much is truly his own strength born from talent and effort and how much is strength granted to him or - justified or unfairly, depending on how you see it - taken from an external source he never should have been the master of (this refers to the Lake and mastery of chaotic powers should by all means and rights solely lie with Arthur, I'll die on that hill.)
It's SUCH A HEADACHE.
