Zzzap overpowering Midknight, taking out bldgs for two blocks

The thing inside Midknight glared out at the hero and gave one final push. The waves of darkness lunged in for a last attack.
The glowing wraith swept them aside with a wave of his hand. The shadows shattered as the air simmered. Zzzap brought his palms up and focused.
Beneath the visor, the ex’s teeth started to chatter.
The blast was a foot across. It vaporized the ex-hero from the chest up, burned a hole through the apartment complex behind him, and went on for another two blocks before vanishing through molten pavement.
