When the doctor was located, Sonic was about follow him on foot when he was given the Blue Star II by Tails, saying that he had prepared it in case something like this happened. Thanking Tails for the new Extreme Gear, Sonic used it to pursue Eggman. As the same time, Sonic met Jet the Hawk, who was after the doctor as well. Seeing this as a rematch for the finals, Sonic engaged Jet in a race to the doctor with the Blue Star II, and eventually claimed victory.
As an upgraded version of the original Blue Star, the Blue Star II strongly resembles the latter. Like the Blue Star, the Blue Star II resembles a blue board with a recess on the front, a yellow stripe ringing around it and a grey foot panel with striations on top. However, the Blue Star II has a sleeker and longer shape than the Blue Star, with double exhaust ports on the rear, the yellow stripe running more along the outer edges and has white highlights alongside its foot panel.
As a Board-type Extreme Gear in Sonic Riders, the Blue Star II is well-balanced in its attributes with average statistics, an average rate of fuel-consumption and is suited for general riding.
Like most other character exclusive Extreme Gears, the Blue Star does not possess any unique abilities. In comparison to the Blue Star, the Blue Star II focuses more on speed, but lacks greater movement control.
