I am working on an 8-bit/Famicom album called "8-bit Trash" (it was something a friend of mines called me. It stuck on me so I used it as the name) and it will be essentially a Megaman OST, but within my own style of composition. While listening through the progress of the unfinished album, I began spriting. Comet (or my real life depiction in the game that doesn't exist) is the one in red, and was created to be the new police of Dr. Light's creations and the world. He was made identical to Rock (or Megaman, but in this plot he is referred to as Rock), with certain upgrades and him being more of an android instead of full robot. He takes a liking to Dr. Light, befriending him, Rock and Roll. Tango is also compatible with him, creating a similar link that Rock and Rush share.
If this was a game, I would not know how to make Comet be different to Rock other than the appearance. But there will be some other difference in Comet's playstyle.
Can you guess who was a recolor of who? Rock or Comet?
