Legendary Pokémon

Real Accuracy

The accuracy of moves as presented in a Pokémon's stat pages in the game or our Attack Database is slightly different that the real accuracy of the move; perhaps you have already noticed by yourself that even moves with 100% accuracy can miss sometimes. Any move with an accuracy of 0, such as Swift can never miss but moves with an accuracy of 100, such as Bite have a real accuracy of 99,6% and therefore there's 1 chance in 250 that they will miss. In order to find a move's real accuracy just multiply with 254 and divide with 255.

Power

• If Hit Point's Individual Value divided by 4 has the remainder of 2 or 3, then P₁ = 1, else P₁ = 0
• If Attack's Individual Value divided by 4 has the remainder of 2 or 3, then P₂ = 2, else P₂ = 0
• If Defense's Individual Value divided by 4 has the remainder of 2 or 3, then P₃ = 4, else P₃ = 0
• If Speed's Individual Value divided by 4 has the remainder of 2 or 3, then P₄ = 8, else P₄ = 0
• If Special Attack's Individual Value divided by 4 has the remainder of 2 or 3, then P₅ = 16, else P₅ = 0
• If Special Defense's Individual Value divided by 4 has the remainder of 2 or 3, then P₆ = 32, else P₆ = 0
• The qualifying Individual Values for a remainder of 2 or 3 when divided by 4 are: 2, 3, 6, 7, 10, 11, 14, 15, 18, 19, 22, 23, 26, 27, 30, and 31.

• If Special Attack's Individual Value is Odd, then T₅ = 16, else T₅ = 0
• If Special Defense's Individual Value is Odd, then T₆ = 32, else T₆ = 0
• Type's Value = (T₁ + T₂ + T₃ + T₄ + T₅ + T₆) * 15 / 63
