This article is about the Life on Mars alien. For the Anacondrai general, see Arcturus (Ninjago).

Arcturus is a Martian minifigure from Life on Mars. He appears in 7317 Aero Tube Hangar, along with four other Martians - Vega, Cassiopeia, Riegel, and Mizar.


Arcturus wears a red suit and had red eyes. His skin is a different shade of green than most of the other Martians, and this skin shade is unique to him.


Arcturus was a spy for the Canyon Martians, who were plotting to steal all of the Biodium so Riegel would surrender Mars.


  • Arcturus is one of only two martians to have a different skin colour than Dark Turquoise, the other being Riegel.
  • He is named after the third brightest star in the sky.
