While often assumed to be the leader of Spyrius by fans, there is evidence to suggest that at least in the UK, LEGO intended the Spyrius Droid to be the leader of the faction. At the very least, the Spyrius Droid was featured much more prominently and usually shown in commanding roles.
LEGO catalogs in the UK referred to set 6939 Saucer Centurion as "Spyrian Sovek with Major Kartofski". Additionally, the Summer 1994 issue of Bricks n Pieces magazine included a short story that again referred to "Major Kartofski and his Spyrian cohorts".
As fans had assumed the "Spyrius Chief" minifigure was the leader of Spyrius, this led to some confusion as to who Major Kartofski was. However, the "Spyrius Chief" minifigure is not in set 6939 - only the Spyrius Astronaut and Spyrius Droid are.
The Spyrius Droid was featured very prominently in all advertising for the theme, and was shown commanding raids on Unitron in a TV commercial and small comic in catalogs of the time (which even specifically showed him in command over the Spyrius Astronaut, who was piloting a larger robot). Additionally, the UK catalogs tended to name a single character from each Space theme, and then use that character as a representative of the theme next to the theme's bios. Space Police II was represented by Captain Magenta, Ice Planet 2002 was represented by Commander Bear, and Spyrius was represented by the Spyrius Droid. All this makes it highly likely that Major Kartofski is the name of the Spyrius Droid in the UK, and not the name of the "Spyrius Chief".
