The chances are, whether we like it or not, the Apollyon-object class will become mainstream, just as Thaumiel did. Some people have suggested not using it at all, in which I reply ''No''. The reason why I disagree with this opinion is because there are already objects that fit 2317's definition of Apollyon (I.E.: 2700, 2399, SCP-871, certain interations of SCP-2998, etc), and that if they don't like the overuse of the Apollyon object class, they could headcanon it out.
Even if there are actually ''poorly'' written Apollyon-class SCPs in the future, the site has dealt with ''poorly'' written SCPs before, and will probably continue to do so for as long as the site continues. Using this logic, the ''Euclid'' object class shouldn't be used because Duke (SCP-083-D) was classified as Euclid. Others will argue that the Apollyon object class will become stale, to which I once again respond with a ''No''.
As I stated earlier, there are SCPs that fit SCP-2317's definition of Apollyon, and they are all unique for their own reasons. SCP-2700 was unique because in addition to focusing on history and science, the creator of SCP-2700 (I'm not going to spoil who it is) actually had a reason for building it: This universe was imperfect. What made SCP-2399 so terrifying had to do with the narrative of ''Hey, we could have died several hundred years ago; now that thing that failed to kill us (Maybe) wants to kill us again.''
I'll continue later, I have to go. Please, don't be afraid to go too hard.
