St George catching a canopy, throwing cinderblocks at Cerberus

St. George shook his head clear, leaped up, and shoved them back. He caught the desk-sized slab of canopy on his fingertips, twisted, and pushed it away from the people. It crashed into the pavement and turned into so much rubble. A fist-sized piece of concrete bounced off his shoulder. He glanced at the trio. “Everyone okay?”
He heard the heavy footsteps approaching before they could answer. He grabbed a chunk of cinder block and plaster the size of a basketball and hurled it at the battlesuit. Cerberus tried to block it but the piece of rubble struck the side of the armored skull. St. George leaped into the air and headed back across the parking lot, into the open and away from the buildings.
