Shocker will shoot at you 3 times you need to evade. Once this is over he should jump at you which is the time you need to be just swinging around the room off the floor. After he lands he will do a power slide attack you should still be in the air swinging around at this time. Once he misses and kneels down you can safely grab some rubble and fling it at him and then begin your attack. Repeat this over and over until you get the first cut scene.
Just be aware if while shooting at you he hits you he may immediately stop shooting and do the jump or slide. He only shot at me 3 times if he never hit me. If he successfully hit me he didn’t continue shooting.
Also it took me 5 attacks to trigger the first cut scene but after the first 2 he didn’t jump anymore, he shot 3 times and slid, no jumping for 3, 4 and 5 when I did it.
Shocker will shoot at you 3 times and you will once again need to evade it. After this he will jump at you which like stage 1 you need to be swinging around the room. Once he jumps he will jump to the center of the room and then jump up in the air and send a shock wave across the floor. This is the time to pick up rubble and throw it at him but you have to land behind him and the shock wave. Once you hit him with the thrown rubble you can start an attack. Repeat this until the second cut scene occurs. It took me 5 attacks to trigger the cut scene.
Shocker will shoot at you 4 times which you will have to evade and then he will kneel down and be exposed for attack. Look up quickly to the ceiling and look for the L1 R1 pull prompt which will lead you into having to push square over and over until you fill the meter. Repeat these steps 1 more time and bam you have your Shock and Awe Trophy.
