Pokemon that aren't really what they are.

[reshikrom]

Topic is self explanatory.I don't think meloetta should be a legendary.What actually makes it a legendary?

 

[HumanDawn]

"Its melodies are sung with a special vocalization method that can control the feelings of those who hear it." A pretty damn legendary ability.

 

[Faye Scarlet]

What makes Articuno, Zapdos, or Moltres a legendary, other than they're slightly stronger than regular Pokemon? Meloetta has some sort of story behind him, right? The Bird Trio didn't get much story at all IIRC.

 

[The Outrage]

What makes Pokemon pseudo-legendaries? Oh right, fan-made categories. Meloetta on the other hand is confirmed legendary (well, illusory Pokemon which puts it more along the lines of being a cryptid than physical god).

Also:

Many famous songs have been inspired by the melodies that Meloetta plays.

Meloetta's possible origins based on this:
Muse|Aoid (Aria forme)|Terpsichore (Pirouette forme)
