* Φθείρω (phthairo): This verb means "to corrupt," "to destroy," or "to ruin," often referring to gradual decay or deterioration. It wouldn't necessarily imply violent destruction.
* Ολλυμι (ollumi): This verb means "to destroy," "to perish," or "to ruin," often implying complete annihilation.
* Απαλλυμι (apallumi): Similar to *ollumi*, but often implies a more complete and utter destruction.
* Διαλύω (dialiō): This verb means "to dissolve," "to break up," or "to destroy," and often suggests the breaking apart of something.
* Καταστρέφω (katastrephō): This verb means "to overthrow," "to ruin," or "to destroy," implying a more violent and complete destruction. This is probably the closest single-word equivalent to the general English meaning of "destroyer."
To choose the most accurate translation, you'd need to specify what is being destroyed. For example, "destroyer of worlds" might best be translated using a phrase incorporating *ollumi* or *apallumi*, while "destroyer of insects" might use *phthairo*.
