I think a lot us agree that Zygarde is one of the most cucked legendary EVER (unless Sun and Moon has something for him in the postgame which is doubtful knowing GF laziness)

But what other legendaries got cucked?

Raikou
>Suicune got Crystal mascot role and a movie
>Entei got a big movie role
>Raikou had no movie, just a shitty special nobody cared about

Arceus
>God Pokemon
>With such a strong position lore-wise it was reduced to be a simply event legend even though it deserved its own game

Phione
>Had no movie
>Stupid way to obtain it
>Outshined by Manaphy
>Nobody cares :(

Meloetta
>First event mon to not have a movie, just a shitty Pikachu short and small role in main anime

Other ideas?
