Mot slutet av Valerian och staden av tusen planeter ser vi kommenderar Arün Filitts K-Tron robotar uppdelade i två grupper. En grupp är med soldaterna djupt ned i rymdstationen, medan den andra gruppen står strax utanför kommandocentret.
At the crucial moment, based on orders from Commander Filitt, both groups of K-Tron start shooting up the humans. At both locations the soldiers seem incapable of defending themselves from the K-Tron.
It is only deep in the station at the Pearl's lair that the K-Tron are destroyed - by Valérian. Only his pistol has the fire power to destroy the K-Tron (which raises other questions - how come Valérian's pistol conveniently packs such a punch, and how come he shoots so well?)
But there doesn't seem to be an equivalent of Valérian at the command center, yet at some point in time the shooting by K-Tron stops.
Så vad höll sig till gruppen av K-Tron på kommandocentret?
