Leo was already raging taking several steps back to keep his distance, but her threat to his sister blew him over any limit of self restraint. Just reaching out his hand palm opened up and focusing on her hamstrings one her right leg and squeezing his hand like it had a stress ball in his grasp. As her leg muscle strained greatly, equivalent to pulling one of her hamstrings causing Axel to feel a sharp immediate rush of pain to her leg. Likely causing the average to lose balance and collapse to the ground. Stopping himself just short of attempting to cripple her, knowing he would get in trouble if he permanently injured students and unfortunately with his power, his weakness was he sometimes didn't restrain his power. Causing play fights leaving kids hospitalized, which is why he didn't have many friends. Which is why despite how enraged he was, he was deliberately controlling his power to inflict temporary pain only, though perfectly ready to make sure she couldn't move from that spot, let alone fight back.
