I was thinking about making these 8 robot master ideas of mine.
Sorted by weapon weekness:
Thunder man -located in new hampshire - factory stage
Cancer man -located in maryland - beach stage
Miniè man - located in mississippi - vicksburg battlefeild stage
Stunk man - located in michigan - forrest stage
Grass man -located in kansas - meadow stage
Pinwheel woman - located in montana - sky stage (with some on ground parts)
Chalk man -located in arizonia - canyon stage
Mud man -located in oregon - lake stage
If you have any more ideas for these robot masters, post a comment.
