paul: he technically does what most(if not all people do on wi-fi): uses powerful pokemon and does not use pokemon that are weak.

he also check their power with the pokedex, it is similar to how we check our pokemons nature and if it the right one: we keep it. if it not the right nature then we either release it or get another one with the nature we want

harley: he is a good character in a wierd way as he is unique as I do not think any character so far is like him.
