Base Stats
When you look at your Pokemon's stat page, you'll see 6 different numbers. These numbers tell you how good your Pokemon's HP, Attack, Defense, Special Attack, Special Defense, and Speed are. But there's another set of numbers behind those stats called a Base Stat. The Base Stat determines how good your overall stat will be. For example, Alakazam has excellent Special Attack because its Base Stat for Special Attack is very high. But it has bad Defense because its Base Stat for Defense is low.
Hit Points (HP)
HP tells you how much life your Pokémon has. Pokémon with low HP cannot survive very long. When a Pokémon's HP meter reaches 0, it faints and cannot battle anymore until it is revived.
