Shut up its awesome, or maybe you should've caught an awesome sandile when you had the chance.
Riceball: IVs are individual values. They're the reason stats are different between pokemon. Each stat gets a value between 0 and 31. The higher the IV, the higher the stat will be. There's some equation that determines what the actual value of a stat will be, involving a pokemon's base stats, IVs, EVs, and level. You know that little descriptor pokemon have now like "Likes to Thrash About?" Those tell you its highest stat, and there are five possible values that stat's IV could be. For example, I have a Galvantula that Likes to Run. So speed is its highest stat, and the highest IV possible is 28. Talking to the IV guy, who says its speed is fantastic, I can conclude that it has a 28 Speed IV, so it'll be pretty darn fast.
