In Japan, the characters in Mega Man all have music inspired names. Double M's name was Rockman, his sister's name is Roll, his bird's name is Beat while two of his enemies are known as Bass and Treble. Coincidentally, the eight bosses in Mega Man X5 were named after the members of Guns N' Roses. Alyson Court who came up with the American versions of the character names used the band member names as a salute to her husband who is a huge fan of Guns N' Roses. Capcom in Japan had no prior influence on Alyson's decision.
