Zzzap looks like the Sun / shooting plasma energy

“Okay, enough’s enough,” I shouted. “I want you both down on the ground now!” I raised my hand and let the energy build. Sparks shot off my fingertips, and I knew looking at my palm was like looking at the sun. The shadows in the alley vanished. They didn’t blink. I don’t think I’d seen them blink yet.
“Get down! This is your last warning.”
The man banged his ruined teeth together with a noise like crunching glass.
In front of my hand the air superheated and did a trick everyone else on Earth needs a supercollider and a magnetic bottle to pull off. An arc of raw plasma scorched its way through the alley, a millimeter wide but igniting everything within four or five times that range. It could burn through concrete like the proverbial hot knife through butter, so searing the old man’s thigh to the bone was no challenge at all. I lost it, and if this had been a normal man, I would’ve killed him, or crippled him for life at best.”
