Mega Man Zero Legacy Collection: All Boss Weaknesses & Rewards

The bosses in Mega Man Zero aren’t like the robot masters from previous Mega Man games. Instead of fighting bosses in a specific order so you have the right weaponry, you’ll just have to decide which missions to take while completing the story. Most boss battles have a specific E-Chip weakness, and exploiting their weaknesses makes this pretty dang difficult game a lot more manageable.

Here I’ll cover all the boss weaknesses and boss rewards for Mega Man Zero 1 and Mega Man Zero 2. Boss weaknesses are slightly more (and slightly less) complicated than in previous games, and there’s a whole lot more bosses here. You won’t be dealing with 8 simple robot masters, you’ll have 15+ bosses and sub-bosses to deal with. They’re all tough, so here’s what you’ll want to get to win.

Don’t forget to change the ‘Save Assist’ setting in the Mega Man Zero Legacy Collection for the best possible experience!
