The Sonic Badge is an object that appears in the Sonic Boom series. It is a special award which is used to unlock levels in the game.
The Sonic Badge is a blue hoop with a small white star and wing on both sides.
In Sonic Boom: Shattered Crystal, the Sonic Badges are used to unlock the levels featured on the World Maps, with each level (except for Seaside Beach, Tails' Workshop, Sonic's Shack and Sticks' Burrow) requiring its own specific amount of badges. The amount of Sonic Badges needed for each level increases as the player processes with the game.
To earn a Sonic Badge, the player must fulfill one of three different objectives given for a level. These include clearing the level, collecting all six of its Blueprints or finding all five of its Crystal Shards, the two latter objectives being exclusive to adventure levels. However, the player cannot earn more than one Sonic Badge from each objective. A total of thirty-four Sonic Badges can be obtained in the game. Obtaining them all will unlock Amy's House on Seaside Coast.
- The Sonic Badge is based on the Sonic logo on the title screen of the Sonic games for the Sega Genesis and Sega Game Gear consoles, like the original Sonic the Hedgehog.
- The Sonic Badge shares a similar design and function as the Emblem: both are based on the Sonic logo, can be collected, and unlock rewards.
