A new series of Sea Urchin type robots which were developed based on the "Orbinauts" & "Spike Spinners" featured in Episode I. The blasting flames of the burners are certainly dangerous, but those fires will spread widely in oily places. Take extra care.

Flamer (ボーラ Bohla?), is a variant of the Orbinaut Badniks created by Dr. Eggman that appears in Sonic the Hedgehog 4. Compared to other Orbinaut variants, Flamers have a slightly different appearance with yellow and grey color scheme. Flamers also have cyan facial section and four spinning flamethrowers instead of spike balls.
Flamers can only be found at Oil Desert Zone where these badniks can temporarily ignite the oily floors with one of their flamethrowers, creating fire waves that spread out on both sides. These are sections in the zone where these enemies move very often, so it's recommended to move carefully if the player can see it. Because of their flamethrowers, the player can have a hard time to avoid Flamers. Despite that, it is possible to defeat them with a Spin Jump, a Rolling Combo or combo attack, which can be activated by breaking the golden monitor.
