This page of the trophy guide to Marvel's Guardians of the Galaxy features a detailed description of the No Way, Nova Corps trophy. You will get this trophy by interrupting the Nova Centurion by calling Gamora to action.
Nova Centurions are the game's elite opponents. You will first encounter the Centurions in Chapter 7. It will happen shortly after you reach the hangar with the large machine from picture 1. Alternatively, you can try to get this trophy in other confrontations with them later in the campaign (e.g. in Chapter 14).
Call to Action is the name of special attacks that you can use during the game. You must first weaken the Centurion, which will be easiest to do with ice attacks. This element is its weakness and you will be able to easily fill up the Stagger Bar.
Once the centurion is sufficiently weakened, the Triangle/Y icon may appear next to the opponent to activate the Call to Action. The difficulty of this trophy is that Gamora must be the one to respond to the call because you won't get the trophy otherwise. Unfortunately, you have no influence on which team member will answer the call, and you just have to keep trying until you get the right one.
Pro tip - if you're in the middle of a bigger fight with the Centurions, and you see that it'll end soon, consider pausing the game and loading the last checkpoint. Thus, you'll start the fight from the beginning and you'll be able to wait until you can activate the correct Call to Action (i.e. the one for Gamora). You can also replay the chapter to easily return to the first fight with the Centurions in mission 7.
