Headstrong Erica

is a technique of Stream's Ignition Ability.

Usage
From his right hand, Stream manipulates his flame tornadoes' rotation to shape an air current into a rapidly spinning disk of condensed wind, akin to a buzz-saw.

While Arthur Boyle defeats Stream before he's able to fully unleash the technique, Stream seemed confident that the technique would deal lethal damage to his target, a second-generation pyrokinetic.
