Sonic Blast, known as G Sonic in Japan, is a platformer for the Sega Game Gear released in late 1996. It was released in North America and Europe in November 1996. The Japanese release was on December 13, 1996, making it the last Game Gear game released in Japan. It was also released in Brazil for the Sega Master System by Tec Toy, SEGA's Brazilian distributor. The Master System version suffers from worse graphics, due to the system's limited palette. The full width of the screen was not used in that version, leaving a gap on the sides; similarly, the HUD was not shifted to reflect the change in screen resolution. Because of its large size (8 megabits), it won't run in the earliest Master System models.

While this game was released at the end of 1996 in the same month as the similarly named Sonic 3D Blast, it is worth noting that both games have little in common (in fact, the game has more in common with Sonic and Knuckles in terms of gameplay elements). No enemies, levels, or bosses, are shared between the games. The story is also completely different. Sonic and Knuckles join together to collect five of the Chaos Emeralds and confront Eggman at Silver Castle.

A prominent feature of this game was its rendered graphics, which had become popular in Nintendo's 16-bit hit Donkey Kong Country. The character graphics also took up a big portion of the screen.
