Something I figured out recently:
All of the main characters' names in the MM series are based off of music
In Japan, Megaman's name is Rockman, and his sister is named Roll, so, together they're Rock and Roll. Protoman in Japan is named Blues, like the genre of music. Megaman's pets are Beat, as in a beat in music, and Rush, as in the band. Megaman's rival, Bass (in America) or Forte (in Japan) has a dog named Treble (American name) or Gospel (Japanese name). And Bass's bird is named Reggae. I also bet Eddie is based on Eddie van Halen.
Wow, the creators of the MM series are awesome XD.
