After completing the Heavenly Tier Transformation, the Thunderflame Emperor Dragon's form hadn't changed much; its entire body was still covered with black-red scaled armor, its physique was strong and fierce, and its tail was long and whip-like.
Three rows of sharp extensions that resembled mountain peaks ran along its back to its tail, and from its double shoulder grew black-red scaled metallic blade-like wings, folded behind and appearing even more thick and ferocious.
The most noticeable change was in its head; not only did dense black mane sprout from the gaps in the scale armor, but also three pairs of feather horns extending back on each side like a pair of red wings.
At the same time, in addition to the split black dragon horns in front, three pairs of sharp, spiral black horns grew backward on both sides, forming a crown-like ring.
