Blaster

Blaster, known as Pon-pon (ポンポン) in Japan, is a Badnik created by Dr. Robotnik. It can be found trundling around first time from Sonic & Knuckles. They appear to be based on a Hercules beetle, although they resemble and behave similarly to Blastoids at Hydrocity Zone. Like TechnoSqueek, they can be found in the original Sonic the Hedgehog 3 manual despite being reserved for a later appearance.

Sonic & Knuckles
In Sonic & Knuckles, Blasters can be found at Flying Battery Zone, where they start fire small projectiles at the player from their horn-like cannon, which harmlessly bounce off any shield type. Blasters also move slowly which does make them less threat. A simple Spin Jump is enough to permanently dispatch them.

Sonic Lost World
Blasters make a appearance in Sonic Lost World, where they can be found at Desert Ruins Zone 2. During the game, it turns out that badniks, including Blasters, got hijacked by the Deadly Six. In the stage, they are moving backwards on the route at medium speed. Instead of shooting projectiles, they will shoot honey to the game screen, obscuring the player's vision. The honey will eventually disappear from the screen and the player is able to destroy Blaster by performing the Homing Attack.
