Zzzap’s powers struggling against Midknight’s

Far above, all three flares snuffed out like old matches. The stars vanished one by one. An inky shadow crept across the moon, across everything.
Inside the armor, lights flashed and power levels wavered. Frost formed on the screens. Cerberus staggered. She rerouted systems and tried to stabilize the batteries as her interior lights dimmed. “What the hell is going on?”
Every walkie-talkie let out a low, flat hiss of static. The guards screamed and the moon vanished behind a black shroud.
Zzzap extended his energies again and trembled as the darkness resisted. The shadows fought and forced his light back to his body. It was something he hadn’t felt in over a year, and something he thought he’d never have to feel again.
“****ing son of a *****,” he said. “It’s Midknight.”
