Charizard
Snorlax example:
Damage = ((((((2*15)/5) +2) * 70* 42/20) / 50) + 2) = (8 * 70 * 2.1) =1,176/50 = 23.52 +2 = 25.52
So, after you do this, then you do STAB, Type and RNG for Crits.
Damage = ((((((2*Level)/5) +2) * Power * Atk/Def) / 50) + 2) * Modifier * Item Boost
Modifier = (Crit(1,2) * STAB * Weather) * Type
Modifier = 1.5 * Type
