Pentaray

The Pentaray was a weapon developed by the people of Solturis.

It fired a combination of Alpha, Infra, Omega, Ultra and Beta rays. It had not been used in one hundred years prior to the arrival of the Daleks, who stole the weapon and substituted a fake Penta Ray in its place. Geltis offered to give the Daleks the operating key, but then turned the weapon against them. After Geltis died, Jareth used the Penta Ray to destroy the Daleks. (COMIC: The Penta Ray Factor)

An artifactual recreation of the Dalek City, based inside the Dalek Dome and created by psychoplasm, had a display of the Pentaray in a room displaying Dalek enemies and victories, indicating that it later somehow came under Dalek control. The Dalek Emperor passed through this room while wondering if his reality could be a fabrication. (COMIC: Liberation of the Daleks)
