Upon being tapped, Jev's metallic body absorbed the electrical charge, acting like a very large capacitor. Whatever he hit next would receive the shock, as he hadn't touched the ground yet.
Jev was starting to get annoyed with the metallokinetics tossing him around like he was nothing, so he decided to try to do something about that. As he flew through the air, he was just about to make his body mimic an extremely bouncy and stretchy rubber when he was slammed into the ground very suddenly, preventing him from shapeshifting thanks to the pain from suddenly being grounded releasing the electricity that had been stored in his body. To add insult to injury, as he laid there in pain, he was subsequently used as a stepping-stone. Now he was really annoyed, but held in his annoyance, just lying there to recover from his injuries and get some recon on his opponents to more accurately assess their potential, letting the pain slowly ebb away as he observed his opponents.
