never.
It depends what you mean by "hero Pokemon"

How does society's definition of a hero evolve throughout history?
Recruit Palkia.
well you grow up
hello, you can evolve Pokemon after you beat the game. then after you will graduate from the guild. you will find luminous spring. the hero Pokemon and partner cant evolve because of a "distortion" in space. though team members can evolve. after you beat pre ending and pro ending you will be able to evolve your partner and hero. Hope this helped!
you have to finish the game then do a mystery misson
its something to do with the space
Give him large ears and eyes, and a pair of wings.
Yes, but only when you recruit palkia and unlock luminous springs. Then, go to luminous springs, where you can evolve your hero and your partner
It Evolved prior to the episode Staging a hero's Welcome!, When it was traveling with May in Jonto!
To evolove any Pokemon that isn't the hero or partner, you must defeat Dialga and have passed the guild's exitting test. To evolve your hero/partner, you must defeat Darkrai alongside cresselia and reach the certain level (which you probably should have to beat Darkrai) or obtain an item (if needed; only for pikachu and skitty) to evolve.
