Mega Man & Bass/Robot Museum

The Robot Museum was already featured in Mega Man 7, as an intermission stage.

Item Walkthrough
If you're looking for a specific CD, sort the table by CD or by character. If you want to sort it back by stage progression, sort it by Walkthrough.

Three Compact-Discs are hidden in this stage, but Mega Man will be able to get them only after most of the Robot Masters have been defeated.

BOSS: Green Devil
This boss is the 5th incarnation of the Yellow Devil, and it's actually a downgraded version of the Green Devil met in the final stages of Mega Man 8.
