Yes, but they're too numerous to list here. Especially since I don't have all the Lore on Grunge down. A good rule of thumb is to try and not do anything that breaks the general themes.I know. I’ll call them something else. Any limits on the history we can add to the world with our characters?
For example; if your character's nemesis attained some sort of power that would actually jeopardize the world of Grunge, they probably would've been taken out by either somebody much stronger, or a group of marginally weaker people working together, almost certainly unrelated to the Kamen Rider Subnarrative, ie; the "Bucket of Crabs" analogy.
Basically, if it's something that the world would need to revolve around in order for it to happen, it probably didn't happen. There's no "Progenitor of All Power" or "One True Chosen" stuff.
