To defeat Rahu III, the final Boss of A New Journey, customize your Robo's legs, gun, and body as follows. For the body, choose something that is heavily resistant. Suggestions include any of the Funky Big Head and Metal Animal Series. For the gun, select something with homing capabilities, range, and perhaps power. The Dragon gun is a good idea. For the legs, choose one that allow good jumping. In the battle, try to hide behind one of the giant circles. Keep a low profile and let your partners do a lot of the work. As often as possible, jump in the air and fire your gun. When Rahu III attacks you, walk away towards the next nearest circle by jumping backwards, firing your gun, pod, and bombs, until your partners come to rescue. When Rahu III has killed your partners, keep firing. When he gets close, hit him with X. When he is in the air or backwards, hit him with your gun. He rarely gets a rebirth, and you will have lots of time. However after the shot, walk backwards firing the gun, pod, and bomb until you reach the next circle; then repeat.
