With the coming of the new games, i've seen a lot of people wishing for non-friendly rivals like the ones we had in XY. However, a good number of anons dislike 'edgy' and 'mean' rivals like Blue and Silver,

I get that a rival must be competitive and push you to your limits. But what does really make a good rival? His/her backstory, interactions with the player, development, pokemon team?

Finally, who's your favorite rival?
