HP: 56
Weakness: Chain Blast
The Yellow Devil is one of the oldest bosses in Mega Man history, appearing in the first Mega Man for the NES in 1987. It was a pain then, and it’s even more of a pain now, having been equipped with a Speed Gear to make matters worse.
The Yellow Devil MK-III enters the battle by reassembling, block by block. Any of the 16 individual blocks will damage Mega Man if they touch him, so use the Speed Gear Booster to jump over or slide under them as they come. Some are easier to dodge than others. If you take damage, you can try to slide behind it as the pieces move to the other side so you don’t have to worry about getting hit again.
When the Yellow Devil MK-III assembles, it fires a shot from its eye. This is the only weak point, and it’s only tangible for a brief time, so quickly fire a Power Gear–boosted Chain Blast directly into it from as close as possible. It only takes two of these to destroy it. When the Yellow Devil MK-III has lost one-third of its health, it can fire five shots instead of one.
When the Yellow Devil MK-III activates the Speed Gear, it turns into nine Chibi Devils that have two attack patterns. They come in sets of threes and the ninth Chibi Devil has an eye on it. This is the one you can damage. Once the two waves of Chibi Devils run their course, the Yellow Devil MK-III reverts back to its normal state.
