Each swing of Khalos's arms produced different effects. He could produce gales of wind, and torrents of hale from swinging his arms. He could summon pillars of ice, earth, and fire that could freeze, pierce, or burn through Ren. Khalos could even create beams of light and trap Ren in a prison of darkness. Khalos was like a force of nature which was expected of a God.
Ren who was receiving everything that a God had to offer was not cowering in fear nor was he repentant in fighting a God, instead, he was smiling that vicious smile of his. In the midst of the New God's rampaging fist, Ren who was unable to counter was smiling fiercely he was enjoying every moment of this battle.
