Barrier Eggman

Barrier Eggman (バリアエッグマン), found in Wing Fortress Zone, is particularly hard. You're trapped in a room by two lasers, and Robotnik is behind the right laser. On the ceiling is a slowly moving laser eye. You need to hit that eight times to beat this boss. The catch is, it begins closed. After a while it opens and turns red. Then you see it flash, and after a few seconds it fires a blue laser beam down at you. Then, after a few more seconds, it closes again. The only time you can hit it is after it opens but before it fires. But it's out of your jumping range, so you have to make do with three tiny platforms (about as wide as you are) with spikes on their bottoms that fly around the room. It's very difficult to position yourself on the correct platform as it flies under the laser eye WHEN it's open. The platforms' movements are very erratic. To make matters worse, one controller error when jumping onto a platform could make you hit its spikes instead.

By all means, TAKE IT SLOW - you have plenty of time, and you should certainly wait for good hitting opportunities rather than make do with fair ones. Get used to the platforms' movement, keep track of where each one is and will be and avoid the spikes (which cause more hits than the laser) and avoid risky moves like hitting the eye right before it fires. And expect to lose a couple of lives before you get the hang of this boss.

Other Appearances

Barrier Eggman also appears in the Flying Battery Zone in Sonic And Knuckles. Here, the wall will slowly move in, and there are no platforms. All you have to do is avoid the laser and eventually it will destroy itself.
