Altair is a Martian with a light green suit. He has orange hair, and appears to be the only Martian to have hair. He drives the Red Planet Cruiser. He also appears in the video game, LEGO Racers 2 in the Martian base telling the racer how he hid a golden brick nearby.
In the January-February 2001 issue of LEGO Mania Magazine, he was described as such: "Altair is one of the younger Martians. He listens to strange music and drives his RP Cruiser too fast. Even so, he is one of the best pilots on Mars. His name, like the star Altair, means 'The Flying Eagle.' "
