Nene

The main villain of the Blue Dragon game and a major antagonist in the first anime, Nene is an elderly man belonging to a humanoid race known as the Ancients. He rules the Gran Kingdom and travels across the globe in a mobile air fortress shrouded in purple clouds, spreading destruction and despair. His primary objective is world domination. Nene is capable of fighting without his shadow, levitating, dodging energy blasts, and absorbing the shadow powers of others to boost his strength tenfold.[6] His profound mastery of magic induced an illness that caused him to age rapidly. To address this, he orchestrated events so that Shu, Jiro, Kluke, and Marumaro would each acquire a light sphere and learn to use magic, intending to eventually harvest their power to forge a stronger soul and cure his condition. He ultimately succeeds in this scheme, though they manage to keep their power. When they finally confront him at the end of the game, he offers them a chance to join him, specifically proposing that Shu become his successor. After Shu refuses, Nene attempts to seize their power again but discovers that it has matured and become their own, making it impossible for him to take. He is defeated in battle and subsequently killed by Zola. In "Blue Dragon Plus," he is reborn and eventually assists Shu and the others in locating the Balaur.
In the anime, Nene captures children to fuel his artificial shadow machine. He initially overwhelms Shu and his companions until Kluke manifests her Phoenix shadow, allowing them to escape. It is later revealed that he is a descendant of one of the Soldiers of Light. During their next encounter, Nene merges with his shadow and Deathroy, only to be destroyed by Shu and Blue Dragon.
Nene owns the Chimera shadow, which resembles a red, dragon-like creature with orange hair and bird-like wings. In the video game, Nene's shadow was originally a red version of Blue Dragon. However, after absorbing the light spheres swallowed by Shu and his friends, the dragon transforms into Chimera, adopting traits from all the other shadows. In the anime, Deathroy owns Chimera, and Nene manipulates it.
