Yi Xing Long is the seventh and final Shadow Dragon in Dragon Ball GT, making him the last major villain of the series. He's the strongest of all seven Shadow Dragons, appearing as a massive, humanoid creature with white, black, and blue coloring. Two large fleshy horns crown his head, and thin feelers above his lip give him a distinctive mustached look. Long black spikes jut from his shoulders, elbows, back, and knees, with additional fleshy spikes on his chest. His abdomen and the back of his head are dark blue, and the One-Star Dragon Ball sits on his forehead—bearing the telltale blue tint and cracks of the corrupted balls.
Like the other Shadow Dragons, Yi Xing Long spawned from negative energy that accumulated inside the Dragon Balls over time. What makes him stand out is his personality: he's the most selfish and evil-hearted of the bunch, born paradoxically from one of the strongest and most selfless wishes ever made. He's completely devoid of compassion, willing to destroy his own fellow Shadow Dragons if it helps him achieve his goal of universal annihilation. He loves taunting his enemies too, constantly reminding them that they're responsible for bringing him into existence.
