Crack is a relatively large aerial Bydo attack craft, flying in formation and firing Bydo Shots. The exact nature of this enemy is difficult to parse as it appears to be slightly mechanical, yet is noted to be more of a biological lifeform that has been molded to appear like a fighter craft. What we know for sure is that it is yet another example of the Bydo's penchant for biomechanical fusion.
