Moltres: You're not supposed to be an legendary, because you don't have any unique designs and appearance just like other Legendaries or Mythicals. Not an bird. You're not belong to our group. I know you are considered as "The Legendary Pokémon" according to the Pokédex Entry, but your rarity are not.

Arcanine: No I'm the legendary! >:( Just take a look at the picture!

The picture was the Bird Trio(Articuno, Zapdos, and Moltres) and Arcanine?
