Wrong Fall

Unlike Adam, Fromund didn't have a helmet when he activated his Power Gene, instead, he had a flaming hoop that was more of an accessory to indicate his status than an element of protection.

Ironically, the flaming hoop protected Fromund from imminent death. He underestimated Adam's new powers. His grip was strong enough to crush Fromund's head, but the flaming hoop broke first.

Cracking.

Cracks traveled through the hoop, releasing hot streams of fire. 

"Grh!"

Adam gripped his hand tighter, wanting to achieve his desired goal - to end the fight right now, no matter the cost or what the consequences were.

But...

The heat was too much. The first flows of fire appeared from a few cracks, but... when the hoop exploded, the situation went to a whole different level.
