Chapter 2: The fight with Jataro in Towa Tower sets you up against another one of the Monokuma fighting robots, this one being related to Jataro's role as Priest. You'll make fair use of the KNOCKBACK bullet that you obtained earlier this chapter, as that is the only way to temporarily disable the robot and aim for its weak spot, which happens to be on its head. You can simply run out of the way of the slow-moving missiles (which resemble Bullet Bills from the Mario universe), but the ones you will need to take care of with KNOCKBACK are the large bomb/balls that he shoots out in pairs of two. Once you end up knocking one back, move away from the other and unload with BREAK.
