>>31494523Dude, what?
>>31494530Yes, sub-legendary is a class within legendaries. They are indeed "straight up legendary." Game Freak was just marketing shit, they don't bother categorizing the specifics to casuals who probably don't care otherwise.
The whole "sub-legendary" categorization is primarily by the players, pointing out the Legendary pokemon, who despite clearly being legendary, are allowed in post-game battle facilities/online multiplayer under normal rules.
And gen VII does define them quite clearly,
>>31494339It is very likely that all of the previous Trios/Quads will have green backgrounds in the gen VII national Dex, and thus will be in the same category as the UBs/Tapus, which are also obviously legendaries.
So, once again. Sub-legendary are just legendaries that for whatever arbitrary reason Game Freak thinks are balanced enough for post-game facilities/online play.
