Why is it bad?... I got this from the oak clinic... but its wrong information... kinda. depending on the indervidual values (iv) and the effort value training, the pokemon stat growth can varry alot, and i mean alot!. Obtained this from http://www.serebii.net/games/ivs.shtml and iv tried it my self(i know its another site but its for evidance). Calculating the iv of a pokemon requires some maths and it shows u it on that site above (move it here, its not (c)). If u catch/breed a pikachu with an iv rating of 27-31 for spec attack (31 is max) and ev train it for spec attack u can easily get a pikachu with an spec attack rating of 400-500 and if it holds a light ball the value will be doubled.... get the drift? The only thing that should worry you now is quick attack/extreme speed which can be counted by having a nature that +def and/or a little def ev training and rock/ground types but if u have surf... With stats like that u can actualy own a lvl 100 anything with a thundershock. if u dont have surf pikachu well.... you wont have a whole party of pikachu. Ops... forgot to mention to change that clinic advice.
