i really dont understand all the ev n iv stuff. even in natures. i even read it and its still confusing. Do u know where i could find plain english?
IV's are sort of like a Pokemon's genes. Depending on the value of a certain IV, the corresponding stat will be above or below average. Some people like to get really high IV's, but this can take forever. If you're a little interested, just keep catching/breeding a Poke for a while and then compare their stats to each other, then begin training the one with the best stats for its purpose.
EV's are the fruits of training. By fighting fast Pokes, your Pokemon learns to become faster, etc. By beating a large number of fast Pokes, your Pokemon will be a lot faster than others of its species who fought, say, strong Pokes. Each Poke gives EV's when it's beaten (refer to the charts on Serebii.net) to every conscious Pokemon that fought it. For every 4 EV's (to a maximum of 255) in a stat, your Poke gets one extra point to that stat upon level up. The Macho Brace doubles the EV's received for the equipped Pokemon, as does Pokerus.
Every personality affects a Pokemon's stats in a positive and negative way (or not at all). For example, a Timid Pokemon would be rather jumpy, resulting in its speed being boosted by 10%. However, as it's easily frightened, it would be reluctant (perhaps even terrified) to go up to a Pokemon and strike it, meaning its attack is weakened by 10%.
