Mega Man 7/Burst Man

Items

 * E-tank
 * Rush "R" plate

Stage walkthrough
Burst Man's stage is based around both water and explosives.

When you start the level, head to the right. The platforming section isn't difficult, but you have to watch out for the spikes which will instantly kill you if you aren't invulnerable. You will also have to clear out the obstacles with the number 3 on them by pressing on its attached disc.

When you drop down once screen, you can either reach the 1-up at the top-left, or go down the right-hand path to collect an E-tank.

Continue heading down into the water. At the waterline, there is a platform that leads to a 1-up, but the level continues underwater.

Underwater route
If you head underwater, you will encounter the mid-stage boss, a crab-like creature. It has a set of attacks, the most common being either a three-shot burst, or a ramming attack. When it is destroyed, head to the left, as you will now be pushed upward to the surface. Continue right and climb up.

At the top of the ladders, you will encounter a disappearing platform section. Rush Jet is best used here. At the end, you will drop down to the second water section.

Get the Rush R plate on the second water section by jumping out of the water when it is at the highest point. Proceed all the way to the right, and climb up to reach the boss.

Burst Man
Burst Man one of the viable choices as the first enemy to attack, since he doesn't have many attacks that inflict direct damage. His weapons are designed to try to throw you against the spiked ceiling to result in instant death.

Burst man is vulnerable to the Freeze Cracker (from ../Freeze Man's Stage/) and has four major attacks. If you do not have the Freeze Cracker, you can easily defeat him by trying to attack as often as possible.

When defeated, you will receive the Danger Wrap, which encases enemies and objects in bubbles.

Attacks

 * 1) Bubble Wall: Burst Man will extend a bubble blower from his head to send out 3 yellow bubbles that are both somewhat hard to destroy and which push you backwards against the wall. He then quickly thrusts his arm into the floor, which forces bubbles to form from the floor that try to push you against the ceiling.
 * 2) *Solution: simply destroy the bubbles and fall off the sides of any ascending bubbles.
 * 3) 3x Danger Wrap: Burst Man fires three sequential bubbles (each one contains a bomb) that will capture Mega Man if he touches one. It will then try to float up to the ceiling to force Mega Man against the spikes (causing instant death). If you destroy the bubble, or it hits the ceiling, without being caught in it, it will drop the bomb that was inside.
 * 4) *Solution: jump over the bubbles when they shoot at you. They don't fly upwards until you jump over them, so be patient. If caught inside, fire like crazy, then get out of the way of the other bubbles. The bombs will fall to the ground, so be cautious of them when they are about to explode.
 * 5) Time Bombs: if Burst Man is hit by either a Freeze Cracker, a Scorch Wheel, or a fully charged Mega Buster bullet, he will jump backwards and throw five yellow bombs.
 * 6) *Solution: Stay against the far wall and jump just before the bombs explode.

Strategies
Burst Man should be the first boss you go after, because he is easy. His attacks are slow, and if you stay near the opposite wall, you should be fine. When he uses the three Danger Wrap shots (the bubbles with bombs inside) stay far to the left and jump over all three in the same spot. In other words, go left, jump right over a Danger Wrap, run left, jump right again, and repeat for the third. While you do this, charge your Mega Buster so you can shoot Burst Man once his attack is over. This should knock him backwards and force him to throw time bombs all over. Don't panic! Stand between the bombs if you can, and jump as they explode if you're feeling really unsafe. With this pattern, he many not even use the other bubble-themed attacks he has, but if he does, feel free to charge your Mega Buster again to stop him as noted above.
 * Mega Buster only

Use Freeze Crackers to take this guy down easily. When the fight begins jump just a little bit so that the shot will go over his head. One of the pieces will ricochet downwards and hit him, cutting off his attack. Repeat this so that he cannot fire at all.
