Sentinel Dragonoid

The Original Dragonoid had two sons. Sentinel Dragonoid, and Apollo Dragonoid. Sentinel was the elder son, but his views were too radical, and he was too proud. He left his family in rage, but returned to join Necronoid to take over the world he believes is his inheritance as a Dragonoid. He detests Dharaknoids, and knows fully that Necronoid was once one, but works with him regardless because it is "necessary."
