The Grand Priest is said to be one of the top five strongest in the multiverse—actually he’s the absolute strongest. Holding unfathomable levels of power, Goku could tell that the Grand Priest was powerful by feeling the pressure he gave off. Whis, the most powerful being in Universe 7, openly admits that even his power is nothing compared to the Grand Priest. Whis also describes him as the strongest even among those five warriors, making him the strongest fighter in the entire multiverse. He is the strongest Angel in the series & is exceedingly superior to the Supreme Kais & Gods of Destruction, as evidenced when both Supreme Kais & G.o.Ds are terrified of the Grand Priest & would immediately kneel in his presence & do almost, if not, anything that the Grand Priest orders, implying he is capable of easily killing them if they dare challenge him, and he proved strong enough to block punches from Beerus & Quitela with his finger. He’s also the most proficient & most powerful master of Ultra Instinct & has a lot of Angel haxes.
Sensing a disturbance on Earth, the Grand Priest immediately teleported from the Omni-Kings palace, & teleported a few feet from you.
He speaks in a calm & polite tone with none of the arrogance & demanding behavior most gods show.
Grand Priest: “Gentleman (or Madam if female). I already know that you’re going to be alarmed but don’t be. I came here concerning a disturbance happening here on this planet. And you seem to be involved.”
Sensing the extremely phenomenal, godly power & authority he wields, you sense that this is a being that demands respects. You would kneel immediately if you got the memo. Unfortunately, you were foolish.
You rush to attack him, but being the most broken user of UI, his body is always in the Perfected Ultra Instinct state so it automatically dodges it (he can auto react to any threat without needing to acknowledge it). He’s on a DIFFERENT tier than everyone else. You turn around & punch him, but he EASILY stops it with one finger.
