Returning to Nefarious' station, you will see he's getting ready to leave for the Great Clock. Hover down to start the fight, in close quarters with the evil doctor. For the most part, let loose on him with all of your weapons. As the fight progresses, he will have Lawrence start up the laser. Now you will have to dash with the Hoverboots around the space station ring. I actually had difficulty staying away from the laser after a while. Nefarious will also shoot at you in an attempts to slow you down. Once you complete the lap, resume the fight. He will have you do another round of running from the laser before the whole thing starts to break apart. Carefully land on each platform while continuing on and you will finish this fight up on Lawrence's UFO.
Now, Lawrence will join the fight by shooting at you, and turning lasers on. Unleash more of your arsenal on Nefarious, who will attempt to move out of your sights. Just keep up the attack and you will send the bucket of bolts back into space.
