I actually was one of the people that looked at every new starter addition the moment that announcement went up because I love that kind of minutia, and I saw no issues with Null being added*. It's a manufactured Pokemon that there are theoretically many of, particularly in VR where the addition of Alolan Pokemon is not related to the plot of the games and is not in adherence with canon to begin with. They're appearing on a completely different set of islands and, in the case of some, regions they aren't native to when the whole point of Alola is that it has a unique ecosystem. So arguing 'well this particular thing is video game canon' when this game has always played fast and loose in order to retain continuity and be a good panfandom roleplay experience is kind of being needlessly pedantic, I feel.

Null being added as starter you have to justify to obtain is perfectly in-line with its status as a pseudo-legendary and the suggested nerfs and completely different VR backstory are in line with that status. It is not a one of a kind Pokemon. It is not, with these suggested nerfs, all that powerful. There is no way for any character to know IC that it's special in any way other than being an experimental man-made pokemon, which is worlds different from a proper legendary and won't take away from the ~mystique~ of true legendaries any. It's kind of baffling to me that you're this insistent about something that really doesn't effect anyone negatively and is being handled with grace and thought by the mods.

*(I should clarify -- if it had been up to me I wouldn't have added Null as a starter either, but aside from shrugging my shoulders and being like 'huh' I didn't think much of it.)
