Armaul

Armaul is a Hammer Bro and a member of the Bounty Hunter Society. He is an ex-soldier of Bowser's army, and wields a red-bladed double lightsaber with curved blades. He often works alone or with Dr. Sykk.

Guardian Era
While Stardown was in custody of the Emperor, Armaul tricked the prison guards into thinking he was ill, then escaped the inner prison and retrieved his lightsaber. He later joined the Bounty Hunter Society.

On Armaul's first official mission against Stardown, he was paired with Dr. Sykk, and they raided the Guardian Headquarters. After Dr. Sykk used her paralyzer on Stardown, the latter and his friends escaped down The Guardian Base Tunnel, where he lost consciousness due to the paralyzer. That was when Armaul came down the tunnel, and was pleasantly surprised to see not only Stardown, but also Kervo, Tails, Amy, and Mark. But before he could capture them, he was discovered and taken into custody by the other Guardians, who received unexpected help from the Doctor.
