The OPness of Move aside, if you want to not have a Nemesis thrown off a clip the Beta Force and Destiny book has a but about resisting being thrown by an opposed Willpower Vs. Resilliance roll or resisting your weapon being pulled away by an Opposed Athletics roll.
Does it really? Awesome. What page is that on? I can't wait to get my hands on the FnD beta.
Page 195 in Force and Destiny, it's the giant red box at the bottom. Also keep in mind that if you make a bad guy Force Sensative any force powers used against him/her can be an opposed Discipline check.
