Arkillo is one of the non-playable characters in LEGO Dimensions 2: The Rise of Enoch, from the DC Comics franchise.
A savage carnivore, Arkillo was recruited into the Sinestro Corps due to his ability to "instill great fear" in others. Taken to Qward, Arkillo's brutal nature allowed him to quickly advance in the ranks becoming the Corps drill sergeant and overseeing the creation of new Qwardian rings. He was a principal combatant during the Sinestro Corps War, particularly at the battles of Mogo and Ranx, where he fought one-on-one against his analog in the Green Lantern Corps, Kilowog. He is a member of the Sinestro Corps and New Guardians.
