Thank you for the evaluations. I think that the text is fine to add then, although I think that it should be slightly modified for easier readability. Is something like the following fine instead?
"Characters that inherit their powers and abilities from a significant amount of other notable characters in their verses shouldn't list powers from these sources as "All the powers in the series", "All powers of group x", or similar. For one thing, this can easily be incomplete due to that not all of the relevant character have been indexed, but it also becomes much harder for our visitors to find all of the implied powers from the recurrently wide amount of involved pages that they would have to check through. Instead such cases should directly mention all of the respective powers, along with the justifications for inheriting them, their reasoning, and which characters that they come from."
