Data-pod
The Krulius had several data-pods, each one contained one alien lifeform. The data-pods stored the alien lifeforms in quasi-digital suspension.
The alien lifeforms were taking from specific locations in the galaxy. Within the Krulius collection were a Sontaran, a Bane, a Raxacoricofallapatorian and a Graske.
The data pods were on a space ship, which hit an asteroid and was going to crash Earth. The Krulius safed the aliens within the data-pods by uploading their digital bio-data into the world wide web, using a digital bio-converter. The aliens were later tracked down by Mr Smith, Rani Chandra and Clyde Langer and released. (COMIC: Monster Hunt)
