|Specifics: Runamuck setting that Mini-spy on fire.|
Runamuck considers wreckage to be fine art; he creates "art" of his own with his friction rifle. It greatly increases the effects of friction on its targets, so the slightest movement can have deadly effects, as the friction between their bodies and the molecules of the air can make them burst into flame or even melt. Its effects last for up to five minutes.
Marvel Comics continuity
Runamuck was unable to hit Circuit Breaker with his friction rifle. If he had, it would've heated up her molecules and made her explode. Big mess!
Runamuck loves a big mess.
