The Blue Star is an object that appears in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. It is one of the Extreme Gears constructed by Miles "Tails" Prower so that the rest of the team could keep up with Sonic the Hedgehog during their missions. The Blue Star itself was especially constructed for Sonic, in case that Sonic wanted to try them out.
The Blue Star is designed as a metal-plated blue hover board with a yellow stripe ringing around it and a grey foot panel with striations.
After Sonic returned to Freedom HQ, beaten and bruised by the Babylon Rogues, the hedgehog was at a loss of how to stop this group, who had promised to come to attack Knothole the next day. Tails, however, presented a solution to this problem, by giving themselves their own Extreme Gear, the Blue Star included, so they could face the Rogues on even grounds. Sonic complimented Tails' work on the Blue Star, and Tails pointed out that though the boards were prototypes they were all functional.
The next day, Sonic arrived on the Blue Star outside of Knothole, along with Tails and Knuckles on their own Extreme Gear, and managed to intercept the Babylon Rogues with their Extreme Gear. Face to face, Sonic squared off against Jet the Hawk on the Blue Star, which eventually resulted in Sonic and his team defeating and driving off the Babylon Rogues.
