Horridian is a humanoid Cerberus-like Bakugan. He has black fur, mostly covered by purple-green armor with golden spikes. His tail also has spikes. Even his collar has spikes. His eyes are glowing red and his teeth are as sharp as razor blades.
In Agony of Defeat, he battled Drago and was doing fine until Drago lost control of his powers and released Zenthon.
In A Hero Returns, Horridian fought alongside the Chaos Bakugan, but went back to Anubias in ball form when the field was about to be deleted.
He appeared in True Colours, being used by Anubias yet again and battled Drago alongside Krakenoid and Bolcanon unveiling a powerful card: Death Metal Army. They were later defeated.
Since Anubias is no longer alive, it belongs to Mag Mel as shown in Interspace Armageddon, where Horridian defeated Pyrus, Aquos, Ventus, and Subterra Ziperators and summonned his Mechtogan; Smasheon. It was later defeated by Slynix. Horridian was likely killed alongside Anubias' and Sellon's Bakugan and Mechtogan when Interspace was deleted by Marucho.

- Horridian is based on the Greek underworld gate keeper, Cerberus, a massive three-headed hellhound.
- He is one of two Bakugan with that basis, the other being Battle Planet's Howlkor.
- Ravedian was Horridian's original name until it was changed.
- He's the first Bakugan that can split into three. As Anubias said that End Guardner Alpha "may split his power level into thirds, but makes the pack three times faster".
