Most powerful weapons system (EU)

Disregarding obvious mentions of Centerpoint station, the Star forge, The death star, and Palpatine's weapon systems. What are lesser known weapons/ships in the EU that caused widespread destruction/devastation? Who shut them down and what stories do they occur in? Could they ever have been used for defense rather than offense?

Sun Crusher

Sun Crusher
Mass Shadow Generator
Dark Reaper

As well as the "Five Brothers", the five planets in the Corellia System.

Corellia
Talus
Tralus
Selonia
Drall

All five have planetary repulsors under the planets surface and can push, pull, or blast anything in orbit into oblivion.

The Executor was a pretty big one.

Jar-Jar Binks,

Actually Star Destroyers in general are pretty beast weapons platforms...well among other various roles, one of the best capital ships in SW mythos.

Oh, the Malevolence from TCW.

Ascendant Spear, Voidstar, Star of Coruscant, Vong ships in general.

They are all super weapons....
