>>16748164not that furfag but here is how it should goes:
252+ Atk Parental Bond Mega Kangaskhan Power-Up Punch vs. 252 HP / 0 Def Fur Coat Furfrou: 106-126 (29.9 - 35.5%) -- guaranteed 4HKO after Leftovers recovery
then, fur is faster, cotton guard is up:
+2 252+ Atk Parental Bond Mega Kangaskhan Return vs. +3 252 HP / 0 Def Fur Coat Furfrou: 162-190 (45.7 - 53.6%) -- 2.3% chance to 2HKO after Leftovers recovery
well, asuume first dmg will be 32%, leftovers heal means it is 26%.
then with cotton guard, takes assume 50%, leftover heals means it is 54%.
congrats, now you got your dog to 20% health and you did hurt khan at all.
now you can:
go for another cotton guard, but you will ded
+2 252+ Atk Parental Bond Mega Kangaskhan Return vs. +6 252 HP / 0 Def Fur Coat Furfrou: 100-120 (28.2 - 33.8%)
