I dunno, it's hard for me to pick on a basis of anything other than music.
Mega Man 1: Elec Man has the best music, I think. Cut Man is also pretty good.
Mega Man 2: This one is so hard to pick since basically all of the music is good. I think Flash Man wins on music though. I also love Bubble Man, Metal Man and Crash Man's music.
Mega Man 3: I think I'd go with Snake Man. Hard Man, Spark Man and Shadow Man are also quite good.
Mega Man 4: Skull Man is best, with Pharaoh Man and Dust Man as runners up.
Mega Man 5: Charge Man... I guess. Stone Man and Napalm Man are maybe the runners up? I dunno, MM5 is definitely a step down in terms of music from the other NES games.
Mega Man 6: Flame Man is definitely the best. Knight Man is my second favorite.
Också, Z1GMA, I felt the need to say hej. Min mor är från Sverige
I have not been to anywhere near Orebro though, most of my family is in Skåne or Stockholm.
