Master & Crazy Hand:
-Easies bosses ever. No need to heal beforehand unless you losing conciousness. Only real problem they pose is their Drill move, that can pile on damage even though it cant KO you. Everything else is dodgeable or Perfect Shield-able.
Rayquaza:
-Has two moves that can KO with <100% damage: The tail end of his spin on the ground and when he rushes horizontally across the screen. All other attacks just pile on damage. According to one of my friends, his head is his weak point so Axe Kick or NAir him there. Watch out for that lightning strike skill, it piles on 40% easy.
Galleom:
-Has a shoryuken that utterly owns you at ~80%. ALWAYS Starts the battle with a standing missle launch that cant hit you if you are point blank range. His "Air Slash" tech breaks shields unless you perfect shield it. Stomps are easily dodgeable. Stay on the ground and you'll be okay unless he readies his shoryuken.
Duon:
-Always starts the fight with either a charging slash or walks up to you to connect with a 3 hit combo. Consecutively uses techniques without rest, which is a problem for Snake and his sluggish Air techs. You can stand on the area between his head, but he'll respond by spinning like a jerk. There is a way to make the battle exponentially easier though, wait for the pink side to fire missles, rush quickly to Duon and let the missles hit him and he'll lose at least 60% of his health bar if not more if all the missles hit.
Petey Piranha:
-Cages do 20% each hit, Butt Stomp does 30~40%. Easy fight though if you stick to spamming Snake's Utilt, Fastest move and allows you to dodge all his hits. DO NOT Shield the Buttstomp, utterly shatters it and then he'll bash you in the face with a cage. Try not to focus on a cage though crazy as it sounds, you can miss when he pulls back then punishes you.
Porkey:
-Always heal up before fighting him, you are more than likely gonna take at least 70% if not more from him. Always starts the fight with a fast charge across the screen and can KO you at low percentages if you are on the wrong side of the screen. His Doom Beam lasts a long time, if you can Air Dodge the first one to delay it then Ground Dodge when it comes back. The Porkey Mines are easy to dodge, but it's easy to lose track of them when dodging Porkey himself. If he pulls off the rapid thrust, you *can* dodge it by crouching as Snake but if it even remotely hits you chances are he's snared you. You can stand on his head with next to no punishment, but it's slippery so it's hard to stay on. Dont try to combo him, just hit with one A move and get out.
Ridley:
-Easy boss, little to no KO moves but can pile on damage. Snake can duck his Electric Charge thing where he flies along the floor and dodge it. His Tail Drag is the damage dealer, you cant DI out of so if you're hit he'll juggle you around. If he copies the Master Hand "Fly off screen and come from the background" move just air dodge it. Nothing hard, but he makes other boss battles tougher.
Meta-Ridley:
-This boss isnt tough, but it is frustrating because he's fast and his moves rely on luck and prediction. He always starts the move with one of two moves: Wing Swipe the stage for ~30% or smack the Blue Falcon, hitting you for the same damage and catapulting you upwards to your doom. Avoid that and it's a battle of patience. More damage Meta-Ridley Takes, the farther left he goes until you are just aiming at a head on the edge of a screen. One thing to worry about though, if he's on the left of the screen and flies straight up, double jump & Cypher if you have to, MR is about to land on the Blue Falcon and KO you if you are standing on it.
