@Glomoro can you really predict what happens next over the "eat-and-gain-powers" trope? the answer is no. it's a tool that allows an author to show his/her creativity, what they find interesting, what they find cool. there is for sure a list of things authors can use and reuse, there is a difference in their creative potential. let's take the "suddenly go to school as an OP mc" trope. what can really happen with this "tool"?
1. mc doesn't learn jack shit
2. all the mob classmates go "omg, this guy is so incredible, where did he come from?"
3. random lady classmate gets her ladyparts wet from how strong mc is
4. there's a tournament among the mob classmates and the mc (omg, who is going to be the winner i wonder?)
that's really all you can get from that. again, the fantasy genre in general has a bunch of things that are reusable, but some things let authors show their creativity, while others are just there for the mood or whatever. the school thing is one of those things that just shows lack of creativity and laziness.
