Protector Sentinel (Trove)

The Protector is a Covenant machine similar in design and purpose to the Forerunner Sentinels, from which they were likely reverse-engineered. Upgrading the Prophet of Regret with Ancestral Perversion in the game "Halo Wars" will equip him with two of these guardians for his personal protection. Like the Sentinels, they have a beam weapon.
