Mega Man's secondary arch-nemisis, Bass. He is built around a negative inversion power source, created by Dr. Light and Dr. Wily. His first appearance is in Mega Man 7, and he has stayed as a main character since.
In the same style as my new Mega Man, here is my favourite Robot Master from Mega Man 4, Dust Man. Essentially, he sucked and blowed. But, I feel he deserved more attention to detail.
I drew this once I watched 'The Secret of Kells', a cute animated movie inspired by Celtic Mythology. It's style matches that used by modern Hanna-Barbera cartoons such as Johnny Bravo and The Powerpuff Girls, and I wondered how my favourite video game character would look in this style. Yay Mega Man!
