Our very own Sean Adamson has completed the sprites for Skull Man, Bright Man, and Ring Man and they have been added to the database. There robots can be encountered in battle by completing the prototype and selecting the Bonus Field mission that's unlocked. The phrase "Mega Man 4 Debug" might also be useful in the future… Thank you so much for your hard work, Sean! Again, I should mention that even though the original sprite sheets were created by Sean I was personally responsible for any non-official recolours and a few other personal edits. As such, please direct any hate-mail towards me and not him. Thank you again! :)
