Description

CP0, more properly known as Cipher Pol "Aigis" Zero, is the strongest intelligence agency among Cipher Pol, working directly under the World Nobles. CP0 is the strongest of all Cipher Pol units, even surpassing the assassination specialists of CP9. It is said that when CP0 is active, world-shaking events are about to occur. Much is unknown about the agents and their abilities; however, the agents of this group are shown to be masters of the Six Powers and are proficient in Haki, as Lucci, Kaku, Stussy, Guernika, Blueno, Kalifa, Jabra, and Kumadori all know Armament and Observation Haki. The agents who wear masks are among the most elite fighters of CP0, stated to be in a class of their own. They are collectively known as the Masked Assassins.

Growth

3 measurements spanning 23 days, net +3. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 54–57 and does not start at zero.
