Atrocitus is one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the DC Comics franchise.
Atrocitus is the leader and founder of the Red Lantern Corps, an antagonist to Green Lantern. His power ring is fueled by rage, as his entire family on Ryut was killed by the Guardians' malfunctioning Manhunter androids during the massacre of Sector 666. This has led him to declare revenge on the Guardians, which he intends to accomplish through destroying the Green Lantern Corps. He has also been a member of the Empire of Tears, the Five Inversions and the New Guardians.
