Critical hits ignore the halved Attack from {{status|burn}} and all stat modifiers. This includes beneficial stat modifiers as well, making it possible for a critical hit to sometimes deal less damage than a non-critical hit, if the user has at least doubled their Attack/Sp. Attack or the target has at least halved their Defense/Sp. Defense. | Critical hits ignore the halved Attack from {{status|burn}} and all stat modifiers.

In this generation only, the probability of landing a critical hit is based on a Pokémon's base {{stat|Speed}}. For most moves, the probability of landing a critical hit is approximately <code>BaseSpeed / 512</code>{{tt|*|(BaseSpeed ≫ 1 ≪ 1 ≫ 1) / 256}}; for example, {{p|Clefable}}, with a base Speed of 60, has about | In this generation only, the probability of landing a critical hit is based on a Pokémon's base {{stat|Speed}}.

As with move accuracy in the handheld games, if the probability of landing a critical hit would be 100%, it instead becomes 255/256 or about 99.6%. | As with move accuracy in the handheld games, if the probability of landing a critical hit would be 100%, it instead becomes 255/256 or about 99.6%. | ||
In {{g|Stadium}}, critical hit probabilities are determined with a different formula, <code>(BaseSpeed + 76) / 1024</code>{{tt|*|(Base Speed + 76 ≫ 2 ≪ 1 ≫ 1) / 256}}. Compared to the handheld games, this causes Pokémon with a base speed of lower than 76 to land critical hits more often and Pokémon with a base speed of higher than 76 to land critical hits less often. As in the handheld games, moves with a high critical-hit ratio are eight times more likely to land a critical hit, giving a formula of <code>(BaseSpeed + 76) / 128</code>{{tt|*|(Base Speed + 76 ≫ 2 ≪ 1 ≪ 2) / 256}}. The effect of Focus Energy now correctly increases the critical hit rate, by changing the formula to <code>(BaseSpeed + 236) / 512</code>{{tt|*|(Base Speed + 76 ≫ 2 ≪ 2 + 160 ≫ 1) / 256}}; this stacks with the use of a high critical hit rate move (<code>(BaseSpeed + 236) / 64</code>{{tt|*|(Base Speed + 76 ≫ 2 ≪ 2 + 160 ≪ 2) / 256}}). While the 1/256 move accuracy error was fixed in Stadium, the probability of landing a critical hit is still capped at 255/256. | In {{g|Stadium}}, critical hit probabilities are determined with a different formula, <code>(BaseSpeed + 76) / 1024</code>{{tt|*|(Base Speed + 76 ≫ 2 ≪ 1 ≫ 1) / 256}}.
