Boss Order
                It's been over two decades since Dr. Wily built his first set of Robot Masters with an exploitable set of fatal flaws. Not having learned his lesson the last nine times, Wily's newest batch is once again riddled with weaknesses. Our own Colin Moriarty exposes these weaknesses with his no-fail Mega Man 10 boss order.
Defeat the robot bosses in this order to take advantage of their unique weaknesses. You'll have to use your Mega Buster to take out the first boss, Sheep Man, but he's a bit of a pushover thanks to the predictability of his attacks. Use the weapons you gain from each enemy to beat the next. 
Sheep Man - Use Mega Buster 
Pump Man - Use Electric Wool 
Solar Man - Use Water Shield 
Chill Man - Use Solar Blaze 
Nitro Man - Use Chill Spike 
Commando Man - Use Wheel Cutter 
Blade Man - Use Commando Bomb 
Strike Man - Use Triple Blade
