Mega Man Powered Up/Weapons

Mega Man begins the game with only his standard Mega Buster. By beating the bosses, he unlocks their weapons.

Damage chart
In the following table, cells in green highlight the most effective weapon against a boss; cells in red highlight the weapon obtained from that same boss.

Notes:
 * For Mega Buster: the first value is the damage dealt with the normal shot; the second value is the damage dealt with the charged shot (when playing as Mega Man C).


 * For Time Slow: the first value is the damage dealt by Time Slow itself (used by both Mega Man and Time Man); the second value is the damage dealt by Time Man's clock hands.


 * For Oil Slider: the first value is the damage dealt with the glob; the second value is the damage dealt when hitting an enemy with the oil sled.


 * For Copy Robot: when he uses any special weapon, he'll take 6 damage after he gets hit by a weapon that counters it and will be knocked back (for example, when he got hit by Hyper Bomb when using Ice Slasher). This applies only for Easy and Normal modes.


 * For Wily Machine: when he uses any special weapon, he'll take 4 damage after he gets hit by a weapon that counters it (for example, when he got hit by Oil Slider when using Thunder Beam). This applies only for Normal and Hard modes.
