Guys, this is huge. You may already know that I love the Mass Attack design of Swordsman Dark Matter,
and was much displeased with the design of the revival in Planet Robobot,
- his eye is the wrong color/shape
- his "hair" isn't dark purple anymore
- his jewelry is missing
- his sword used the design from his Dream Land 2 artwork instead of Mass Attack's sprites...
- and the confusion of his sword being the Rainbow Sword, or at least a duplicate (Note: The Rainbow Sword has never received official game artwork)
BUT LOOK AT THESE!!
His iris is no longer yellow (or black, but at least it's dark purple/indigo), the whiteness has returned, and the shape is fixed (though the Mass Attack design bore more similarity to that of a ring & Dream Land 2's artwork & sprites.) The chest plate seems to have been changed to a scarf. Plus, the sword (while no longer all dark purple) isn't the same as the Planet Robobot model. It's entirely new, while just very similar to that of Mass Attack's sprites. Not the entirety of what I wanted to have fixed, but still satisfying.
My conclusion? The design changes in Planet Robobot were to signify the fact that he was just a clone, and has been absent from a traditional platformer for some time now.
