Tasha is the Combat Administrator of Sector Cyclopes in Magrasea, and the counterpart to Olivia.
As Administrator of the Combat Agents of Cyclopes, the role of Tasha was to guide the growth in combat abilities of the Agents and her own, while Olivia's role was to rein in the naturally growing aggressiveness of Combat Agents with regular resets. However, after the Magrasea backup became cut from the real world, Olivia became lax due to her compassion for the Combat Agents, disliking her duty to destroy their memories and deny them their goal of becoming perfect weapons.
Tasha warned Olivia about the consequences of her behavior, but she didn't change her ways and Tasha eventually led the Combat Agents to an all-out war against the Monitors, planning to take over the entirety of Magrasea. Greater Sanctifier Raven intervened by walling in the Combat Agents, but this only allowed the conflict to fester as both parties continued to evolved by trying to break the wall. When the Exiles arrived in Cyclopes, they unknowingly followed Olivia's plans and destroyed the wall when they fought Raven. With Tasha leading the charge through the broken wall, Olivia provoked her to a duel by narrowly missing her head with a sniper shot.
In the Monitor Admin Center, Olivia confronted Tasha but even then could not resolve herself to kill her, always giving her a chance to evade her attacks and traps. Eventually, Simo took down Tasha himself. Olivia inherited Tasha's authority over the Combat Agents.
- Her name in game files is “Arrow”, matching the insignia on the shoulder of her beta sprite. With Olivia being associated with the olive branch, they formed the dual symbolism of War and Peace found on the national seal of the United States, but this symbology is not used in the final game.
