P-12 - a Product 12 seen accompanying A2. Despite A2's reluctant trust to her due to being an outsider from an another world, P-12 still gives her best to help A2 in their folly.
C-1002 - a Product 12 encountered by Counters, she was known as "Lively Product 12." C-1002 took their code-names from a spy movie they watched alongside her company.
B-0006 - a Product 12 known as "Cautious Product 12." She shows genuine concern over her fellow Product 12s, replicant or not. Wanting nothing more than peace and coexistence amongst all mass-produced models due to the D-Wave event, unable to bear the conflict amongst each other. She was eventually killed by 6000-D for this.
6-000D - a Product 12 known as "Taciturn Product 12." She is actually the event's main antagonist.
