Flashers are rather small Badniks comparing to other models. Based off of fireflies, they have a small red head with two grey antennae and two eyes with black dots for pupils. The upper part of their body is black, while their underside is flat with an electric bulb covering it.
Flashers appear exclusively in the Mystic Cave Zone where they float around. Most of the time they are found in corners, narrow routes and can even fly through walls. Unlike enemies like Whisps, they do not usually move around in groups. Their flying pattern is also rather erratic.
When Flasher stops in one place after floating for three seconds, it creates a flashing barrier from its bulb that makes it impossible to hit it and cause damage to the player. Even when the player has obtained Invincible or has gained invulnerability from taking damage, the Flasher stays invulnerable until it lowers its shield, upon where it can be taken out with a Spin Jump. With this ability, Flasher can block narrow routes.
Powers and abilities
The Flashers are capable of flight, allowing them to move through mid-air. They also possess the ability to generate a completely impenetrable electrical force-field around themselves that can block any attack and as well electrocute those that make contact with it.
The Flasher mk.II is a variant of the Flashers from Classic Sonic's world. These Badniks possess the Flasher's body, but possess also legs that allow them to climb along surfaces, releasing electrical waves as they go. They only appear in Sonic Mania and Sonic Mania Plus.
