Lash is a Commanding Officer featured in Advance Wars 2: Black Hole Rising and Advance Wars: Dual Strike as one of the main antagonists. At first purely an adversary for the Allied Nations to overcome, Lash lends her expertise when she joins with the Allied Nations against the Bolt Guard. Specializing in using terrain to devastating effect, Lash's units tend to be very jack-of-all-trades on open fields or straight fights. In a forest, city, or mountainous terrain, however, they become frighteningly powerful. Lash's CO Power and Super CO power amplify this specialization immensely, allowing units to ignore movement penalties caused by - and double the benefits of - terrain.
