Just bubble the guy. That's all he had to do. The punk looked like he was in the process of powering up. Which would be perfect timing. That was when some guy that was on fire dropped down next to Alex out of nowhere. Before he could even react Mr. burning man fired off a broad ray of red light at the villain. Sending the guy flying backwards clear out of the alley and high in the air. Alex had little time to think before he saw the man jumped away behind his wall and add his own red barrier to protect the civilian. "Brace yourself!" Realization dawned on Alex as the villain came crashing to the ground. "SHIT! Hold on!!" He backed up straight into the wall, crouched and held his arms crossed in front of himself defensively. He began fortifying and adding layer upon layer of fields across his body, even adding more energy into the wall behind him before the villain hit the ground. followed by a blinding green light.
BOOM
Deafening, that's the easiest way Alex would have described it. The proceeding shock wave had thrown Alex against the wall hard, shattered most of the layers he had placed over himself and cracked the wall. The light didn't blind him thankfully but Alex could barely hear anything over the high pitched ringing. The villain laying on the ground steaming and not moving. A quick snap of the fingers and the unconscious bomber was safely bubbled and bound. It was best not to take any second chances after that blast. After turning slowly due to the sudden feeling of nausea Alex released the wall. it looked like the Heroes barrier had taken next to none of the shock wave, him and the civilian both looking a lot better then Alex was feeling. "Everyone alright?"
