From Sonic Retro
|Game: Sonic Advance|
The Mirror (ミラー Mirā) is a pointy defensive robot appearing in Sonic Advance and found in Egg Rocket Zone and Cosmic Angel Zone. It flies around left and right, occasionally opening to fire energy shots the way it's facing. When it opens, this is also your chance of attack, however, avoid touching the energy shots.
This Badnik does not appear when playing in Easy mode.
