Onuwa Gallia Tacci was a Mgalekgolo fighting under the Covenant Special Operations Lance "Righteous Hunt". Onuwa's job was as the "Heavy" of the group, fulfilling many roles as either a distraction, a shock trooper, or a "bomb defusal" unit. Thanks to his enduring strength and durability, Onuwa served as a powerful asset to the Lance of the Righteous Hunt until its dissolution in 2552.
