Over Power Anime & Game Character Skill

Hello guys, just passed in my mind and like to shared with you what do you think the most over power anime and Game character skill that you have encounter until today ?

for me :
Ains `Oal Goan from anime Overlord hes strategic and skills are way too OP
DBz im guessing most of you know about this anime no need to explained more further :D
One Punch Man - why i put this anime on third list is just unrealistic but its fun to watch something that beyond your imagination

this is just some from my list. how about you ?
