Mega Man 8 Boss Rush+Weaknesses 

My own reasons for why other bosses are weak to the weapons that are their weaknesses... Yadokargo: Mega Ball (Kicking a ball so hard can knock out a shell and it can send a crab away if is possible) Astro Crush (Meteors are too strong for a shell survive it if Meteors are threats to multiple locations of Earth) Thunder Claw (This boss is crab-themed and water conduct electricity so electrcity kills or paralyzes living organisms of aquatic animals, like crabs with ease) Homing Sniper (Shells aren't explosion proof and shooting missiles on a crab is basically animal abuse) Ice Wave (Ice freezes water for the aquatic animals not move it) Water Balloon (Water may be able to rust the metal of his shell) Mega Buster (Charging enough solar energy causes water to evaporate for the aquatic animals be disintegrated easily. Mega Man's real name is Rock and Rocks might be heavy enough to crush a crab and the shell) Duo: Ice Wave (Freezing him might stop him from using his comet form and other attacks. Ice is water in solid state, thus, it can rust the metal of Duo's robotic body and the water might not be healthy for his electrical components/electronics) Atetemino: Mega Ball (It is the only weapon that can reach and damage it for the boss be a homage to "Whack-A-Mole" by hitting hard enough to damage it) Bliking: Astro Crush (Meteors are too strong for that plane-themed boss survive it if Meteors are threats to multiple locations of Earth) Super Bass: Astro Crush (Meteors are too strong for that flying boss survive it if Meteors are threats to multiple locations of Earth) Green Devil: Thunder Claw (Electricity emit light to blind his eye. Electricity also might shock him enough for him not control his slime body correctly once it try to conduct the thunder) Wily Machine 8: Astro Crush (Meteors are too strong for that machine boss survive it if Meteors are threats to multiple locations of Earth) Flame Sword (Fire might ignite the ammunition of/melt his cannons. Swords might be useful to slice a cannon in half if is sharp enough and fire also melts the metal of that machine. That machine might be bad at close combat for this weapon be effective on it) Wily Capsule Great: Flash Bomb (Bombs easily destroy buildings so that machine might not be too durable to survive more multiple hits) Flame Sword (Swords might be useful to slice a machine in half if is sharp enough and fire also melts the metal of that Capsule)
