Karnov - Bad Dudes
Karnov is the specialized boss theme heard when you're fighting Karnov in Bad Dudes, the boss of stage 1. The song is nearly identical to the Dragon Ninja tune heard for every other boss, but the melody of this track uses a tune very similar to the one heard in the stage music of the game Karnov (ARC).
The official title come from the Deco History: Data East Game Music Scene One album where the song is named 忍者火流野夫 (Ninja Hi Ryu No Otto). This doesn't have a known translation, but the words mean "ninja fire style field husband." A ninja using the fighting style of fire certainly fits Karnov, but the last two words don't make sense. They may be a name or figure of speech that doesn't translate to English. For now, the title remains based on who the boss is rather than the official wording.
