From Elfen Lied (NOT anime/manga accurate for simplicity)

The world's greatest hero...

Gnarl has chosen you to be the Overlord

Milleena (pick your poison from which game) stalks you

The best detectives on the planet

Sister of Alex Mercer

King of the kaiju

You have wandered into the garden of Ku'Gath

After much trial, you meet the Prince of Perfection himself

The Storm Hawks' carrier pilot
