I like Isekai and OP protagonists, and I like it when the protagonist overwhelms the puny natives... Like how Ainz and gang in Overlord just massively overwhelms everyone with their ridiculously OP combat abilities... or how the protagonist in Release my Witch, overwhelms the natives with his OP "modern" tech...
And I especially like the parts which are written from the point of view of the puny "ignorant" natives who are getting stomped, and haven't got a clue about what they're really dealing with, and their often sensible, yet hilariously wrong judgements...
Also... While I don't think the OP abilities really need to be "earned"... For example, the protagonist asking some "god" for some cheats, and being granted said wish for no reason in particular, with which they then stomp the puny natives, is just fine... As is some gamer getting mysteriously isekai'ed as their OP video game character, with its OP abilities intact... I hate it when some random nobody gets isekai'ed, as their random nobody self, and then start displaying some distinctly non-nobody abilities, which it turns out, they actually had all along...
Like some guy from our modern world, overwhelming some warriors in a medieval world, in a sword fight, because they had practiced some kendo as a hobby at some point in the past... OR how in Release that Witch, the protagonist was an impossible "know it all", even before he got his "cheat".
