Eshu

Eshu (エッシャ, Essha), sometimes referred to as Eshi (画師, Artist) is a mysterious figure within the Pokémon world, having created a good amount of legends around his person in recent years. He became known due to his unexplained actions of 7 years ago, where he would challenge each and every Gym Leader but forfeit every match when he was just about to win. This portrayal of arrogance infuriated many trainers, but for some reason anyone wanted to challenge him couldn't get a hold of any information on who he was or where he was going.

After this, Eshu wasn't seen again for years. Every now and then, a lone trainer would come across him on their path to becoming a Pokémon Master. He would accept every challenge, console them when they lost and offer food to them and all others, as well as point out shelters when the nights where uncomfortable. A protector of travelers somewhat, even these trainers would find that as soon as they arrived at their beds and turned around to thank Eshu, he was already gone. Interestingly, Eshu also is often present whenever a Pokemon is about to die, going as far as putting wild Pokémon out of their misery when they have no chance of survival.

A few weeks ago, Eshu made his first public appearance in seven years within the capital. Though few remember who he is, much less recognize him, he no longer makes any kind of move to conceal his existence. His motives are unknown, but there doesn't seem to be something particularly evil on his mind. In his own words, Eshu much rather prefers to "watch from the sidelines".
