Light wave sickness: Difference between revisions

'''Light wave sickness''' was a sickness fatal to the [[Dalek]]s but not fatal to [[Spiridon (species)|Spiridons]]. The Daleks conquered [[Spiridon]], hoping to discover the secret of the Spiridons' [[invisibility]] and reproduce it for their own use on an army kept in [[suspended animation]]. Only one Dalek used it, but it died from light wave sickness. The Dalek was examined by the Third Doctor. The invisible Dalek was discovered by the [[Third Doctor]] and a group of [[Thal]]s. With each invisibility experiment, the Daleks became more proficient with becoming invisibility though it was enough to satisfy the [[Dalek Supreme (Planet of the Daleks)|Dalek Supreme]] when he arrived on Spiridon to release the army when it was time to begin the invasion of the galaxy.

After being the Daleks' prisoner for many years to try and restore the Spiridons' invisibility so that the Daleks could duplicate the process, the [[Seventh Doctor]] released a contagion that gave the Daleks the light wave sickness. This destroyed all the Daleks occupying the planet, while affecting the Doctor with the light-wave sickness until he returned to [[The Doctor's TARDIS|the TARDIS]], the TARDIS's dimensional stability keeping his cells immobilised until they overcame his cellular paralysis.
