First of all, this amazing database was not made by me. Peterko from Smogon Community made it, and he has granted me permission to post the link here.
Second, I have only posted the link, not the actual database, to follow Peterko's wishes. Please do not complain about this.
This database shows the stats, natures, moves, etc. of almost all the Pokemon in the Battle Frontier (Lv 100).
As you can see, it is EXTREMELY useful and took a lot of effort from Peterko. You can use it to calculate your Pokemon's speed to outspeed a certain Pokemon, or check your opponent's moves...etc.
(And yes, I did rate it five stars myself, so that more people would notice it.)
