About Mega Man 4
Released in 1991 for the NES, Mega Man 4 continues the thrilling saga of everyone's favorite blue hero in the classic Cartoon Games style. This time, the stakes are higher than ever as a new villain, Dr. Cossack, steps into the spotlight, bringing his own fortress and a uniquely themed team of eight Robot Masters: Bright Man, Toad Man, Drill Man, Pharaoh Man, Ring Man, Dust Man, Dive Man, and Skull Man. Each Robot Master comes with their own vibrant stage, filled with tricky hazards, challenging enemies, and an energetic retro charm.

With stunning pixel graphics, a memorable soundtrack, and adrenaline-pumping platforming, Mega Man 4 stands as a cornerstone title in the series, perfect for fans of retro Cartoon Games and newcomers alike.
