Trivia: The promotional commercials in Japan for this game show Mega Man using the wrong weapons against the Master Bots. Like using Thunder Beam on Guts Man, who is weak to Hyper Bomb. Using Rolling Cutter against Fireman who is weak to Ice Slasher. And Fire Storm against Ice Man who is weak to Thunder Beam.
Trivia: Mega Man 1 is the only platformer in the Mega Man franchise with a score system. However, it doesn't really do anything. You can't save your score, it doesn't grant extra lives, and it has no effect on the game really in any way other than score pickups instead of health at times. They actually carried this over in the PSP remake of Mega Man Powered Up, where it still functions much the same useless way.
Trivia: The horrendous box art for Megaman 1 has a notorious design for the titular character and is regarded as one of the worst box arts in history. But as a nod to this, Bad Box Art Megaman appears as a playable character in Capcom x Tekken and appeared in the cancelled Megaman Universe game. Bad Box Art Megaman appeared a few times in the Archie Megaman comics, usually in the Short Circuits comedy strips, or even on a variant cover of Issue #33.
Trivia: Originally, Megaman 1 was intended to have 8 Robot Masters, which would become the standard starting with Mega Man 2, but they had to reduce it to 6 due to limitations at the time. One of the cut Masters would have been Bond Man, a robot who used glue as his main attack. He was later planned to be included in the Powered Up remake of Megaman 1, but they went with Oil Man instead.
