Like most fans of Pokemon They will know, in their games there are many movements of different types that can be physical or special. However, there is also a very special type of movement called fulminating blows
(also known as ONE-HIT K.O. in English, abbreviated as OHKO). These are movements that weaken the target in one fell swoop, regardless of the difference in levels or statistics between the attacking Pokémon and the one receiving the hit. These movements have in common that their initial PP (Power Points) are 5, and their accuracy is 30 (the lowest of all). This is so that obviously these movements are not abused, because they would quickly end the battle (in fact they are prohibited in the competitive field).
This effect is produced by the following movements:
Guillotine
Fissure
Perforator
Polar cold
Same destiny
Mortal Sing
Self destruction
Explosion
Legacy
I want a cure
Sacrifice
We leave you a video where you can see them all in action in Pokémon Sword and Shield:
