It came during a mission to stop alien smugglers moving Apokoliptian tech through Gotham.
Kael was doing fine—until a child got caught in the crossfire.
He flew.
He roared.
His body ignited in golden light, hair rising, aura flaring like a solar storm. The smugglers were flattened instantly. Even Superboy stumbled backward, shielding his eyes.
Kael stood in the center, trembling, breathing like a beast.
When his eyes cleared, he whispered, "…I didn't mean to…"
And then he passed out.
