how come no one talks about the interesting precedent Bloodmoon Ursaluna gives?
It's a new form of the original but essentially a completely new pokemon. It doesn't have the same stats (distribution or number), it has its own ability and signature move, and plays differently than that original
it could have just been a brand new legendary pokemon but its not

we've seen "special" pokemon that are alts of regular ones before like red Gyarados but this is completely different. its not like they made red Gyarados a super charged special attacker

Why haven't we seen more special versions of mons that aren't just regional variants? What new ones would you like to see?
I think an Onyx variant that's given stats it deserves would be cool
