I honestly have no idea why they come after the Legendaries in the Pokédex. They are termed "Pseudo-Legendaries" because they have the strength of Legendaries. Maybe it's done to mark them out as different, as destroyers xD. I think Larvitar is rarer, since you can catch Dratini with a FISHING ROD xD.
