Mega Man X Legacy Collection: How To Beat Every Boss | All Weaknesses Guide

The Mega Man X Legacy Collection covers all eight games in this side-scrolling series, and if you’re new to the games, we’re here to provide an easy-to-follow list, showing you the easiest order to follow if you want to defeat every boss using the right weapons. Just like the original games on the NES, Mega Man X can select which bosses to fight — but each boss has a weakness.

Part of the fun is discovering all the weaknesses for yourself, but I totally understand if you just want to breeze through. We are talking about eight games in the series, after all. When you defeat a boss, you’ll earn that particular boss’ sub-weapon, and using the right sub-weapon on the right boss makes these difficult encounters insanely easy. After struggling to complete the level, who wouldn’t want an easy boss encounter? Here’s the Mega Man mega fan’s guide to destroying every X-boss, in order, for all eight games in the complete collection.

[Work-in-Progress: Some minor changes were made in the Mega Man X Legacy Collection. The version used and boss names might be different in your version. We’ll update as we complete these levels.]

All bosses in Mega Man X 1-8 have weaknesses. You’ll need to defeat at least one boss with just your X-Buster. The rest are a cake-walk if you unlock their specific weakness first. Here are the most common orders devised online for each game — including the weaknesses for the endgame bosses.
