As a dragon, Kent's main elemental affinity is the Chaos Flame. He had already witnessed how Chaos handled that flame in the past.
Although he had yet to awaken his Chaos Aura and Chaos Heart, his affinity for the chaos flame had already reached the Harmony stage. This means he can harness the Chaos flame much more efficiently this time.
So now that he has awakened 25% of his bloodline, and he can take on his True dragon form, using the flame for attacks like dragon breath is now possible.
He saw how dangerous his chaos flame got when Chaos went to train in the blood system. Back then, Kent saw that the stronger he became, the more deadly his flame.
It was one of the many reasons for his dominance in that region.
However, Kent couldn't help wondering just what kind of ice he would awaken and how dangerous he would become if he were to wield both Ice and fire. Breathing ice is something only the Ice Dragons, or as they prefer to be called, the Crystal Dragons, can do.
