Biography
Grugger, his aide Brotadac, and his marauding band were hired by Meglos to bring an Earthling to Zolfa-Thura. Once there, Meglos made a deal with Grugger, promising him power in return for the Tigellans' Dodecahedron.

Grugger took him to Tigella to steal the Dodecahedron from their underground city on his home planet of Zolfa-Thura. Grugger and his party stayed with their ship. They captured Romana and had her lead them to her ship. However she led them in a circle before initiating a Bell Plant attack upon them. Grugger broke free as did his party. They then attacked the Tigellan city and managed to beat back the defenders.

Together with Meglos, they left for Zolfa-Thura. Once there, they set up the Dodecahedron so that it could fire a powerful blast. Grugger requested that Tigella be that target, angry over the loss of life sustained there. The Fourth Doctor reverted the controls so that Zolfa-Thura was destroyed along with Grugger. (DW: Meglos)
