Mega Man X/Storm Eagle

Sky Stage
You'll begin this stage on a large platform at the bottom left of the map. Your goal is to reach the far top right area.

First head right and jump on one of the moving platforms, but be wary of the sky claws that will attempt to grab you. When on a moving platform, you're extremely vulnerable to getting caught; and the end result is usually a nasty fall into the pit below. Your best bet is to use some of your tools, like Chameleon Sting or Boomerang Cutter to take them out while they are above and away from you. Don't be afraid to bail and jump on another platform, it would be better to waste time on that then chance dying.

Boss: Storm Eagle
Storm Eagle is probably the easiest boss in the game, since most of his attacks are actually attempts to push you off the edge of the map. He'll either flap his wings to push you off or fire a tornado projectile that does the same thing.

His two damaging attacks are dropping eggs that split into several birds and dive bombing. If he takes to the skies, he's about to divebomb. Simply dash in one direction until you see him coming, then either 1) keep moving in the same direction, 2) switch directions or 3) jump. Alternatively you can use this time to blast him as well; if he dive bombs you, dash in the opposite direction, turn fire and then get out of the way if you need to.  You must be very quick to do this without taking a hit.

After dive bombing, Storm Eagle will hover down from the top of the screen and attempt to throw eggs at you. Use Chameleon Sting or a fully charged Mega Buster shot to hit him while he's up there. If you hit him right when he starts hovering he'll end up ignoring this attack phase and either return to dive bombing or land and attempt to blow you away.

The best time to hit him with Mega Buster shots is when he's just on the ground; don't even bother powering up your shots since you'll be able to hit him so many times with regular ones. However, Chameleon Sting is always the way to go in this fight.
