Zzzap transforming / incinerating clothes, scorching wood, bursting glass, blistering skin

In the back of the truck, Barry’s eyes snapped open, then clenched shut. He reached down into himself, found the trigger fused into his DNA, and flipped it.
Everything went white.
The blankets beneath him burst into flame as his clothing incinerated.
Arcs of raw power spat and twisted out to every metal surface. Ilya felt his skin burn and blister and threw himself off the lift gate. He blocked his eyes as Big Red’s paint seared off down to the metal and the wooden planks lining the truck bed scorched black. Two of the solar panels flared and burst.
A second sun shot into the air.
