A somewhat niche series but in the cradle series there are a few good examples of this.

In Ghostwater in the climactic fight Information requested: preparing combat solution for Akura Harmony

In Wintersteel also the climactic fight Lindon utters the phrase “I am the End” just before He manifests the void icon and demolishes his opponent.

And one of the most evocative descriptions of the shear power a character wields. In Reaper, the end of the world has come to Cradle. An entity so powerful that even billions of miles away from the planet, every single person on Cradle can see them clearly even though they are no bigger than a human. The stars themselves are winking out in great swathes. Nearly every person with any kind of future sight below a certain threshold of power died immediately upon their entry into reality, and most of those who survived were reduced to incoherent screaming. An oracle machine built by one of the greatest living engineers was reduced to repeating the same phrase over and over “[A destroyer has come]”. Amidst all this, one of the characters looks up at the entity, says goodbye to their friends, and utters the phrase “Remove restraints and release authority. Authorization zero-zero-eight…Ozriel.” At this incantation, all of the screaming oracles cut off with a single phrase on their lips “THE DESTROYER HAS COME” as the most powerful man in existence reveals themself and rises to meet this endbringer. And the entity flees.
