Tangaran

Summary
Tangaran was the demon designated to be the opposition to Ardon. He is much crueler and more vicious than Ardon, holding very different ideologies and being generally more evil.

Origins
Tangaran was born very shortly before Ardon's rise to the God King of Hell, and once he was fully grown, he was chosen by other demons in hell, unhappy with Ardon, to be their new leader.

Clash
After Ardon's refusal to even attack Avalon, many demons revolted and supported Tangaran in rising to power, and contributed their power to him before he challenged Ardon to a duel. The duel ended poorly for Tangaran, who ended up cheating and escaping, launching a war against Ardon and his armies. This war was very short lived, and abruptly ended when Ardon seemingly killed Tangaran. However, due to Tangaran's nature as a partial god, he was not allowed to completely die in such a way, and instead was split into five shards, which were split across to different realms and manifested as individual demons, though some of them lay dormant for different periods of time before awakening. It is unknown what would happen should the shards come together again.
