Beautiful and deadly leader of a terrorist organization called Snake, the main rival of Canaan after killing her mentor. She claims her biggest strength is not giving in to emotional impulses like Canaan.
Before she became the leader of the Snakes, Alphard was a young girl who Siam also referred to as "Canaan" as he taught her the ways of being a soldier. Apparently, Alphard grew a bit jealous when Siam taught similar lessons to the current Canaan. She disagreed with Siam's teaching that a soldier who could not let go of hatred was worthless, so she tricked the two of them into boarding a train going across the desert, and then killed Siam while Canaan watched. Alphard doubled crossed them for her own personal gain and she was working with enemy organization to sabatouge their mission.
As the leader of Snake, Alphard apparently had a hand in the CIA's nefarious attempt to infect a small Chinese village with the Ua Virus, then provided a facility where the survivors were taken to be experimented on. It is unclear what her true goals are, or if she even has any, but what has been revealed is that Alphard uses her position as a terrorist leader to sell her services to whatever side needs them in order to provoke or continue a conflict where the Snakes will be needed as either enemy or ally in a perpetual cycle of violence. Even the "war on terror" is simply seen as another profitable opportunity to her, when she infects the American President with the Ua Virus at the Shanghai anti-terrorism conference and then afterwards offers to sell her services to the Vice President. When Liang Qi tries to lure Canaan and her friends into the Factory, Alphard simply hands over her experimental data on the Borners to a Japanese spy and then lets her destroy the facility while the others escape.
Despite all the horrible things that Alphard has done and is still capable of, she seems either incapable or unwilling to feel any emotion outside of an occasional smirk. When Cummings and Liang Qi both cry to her about love, she seems confused by their emotional outburst, even leaving Liang Qi to die on a few occasions. However, she seems to share a strange relationship with Canaan and even hinted at knowledge of Maria from a couple years ago.
Even though Canaan tries to kill her on a few times throughout the series, Alphard doesn't even view her as a threat that needs to be killed. In Ep. #12, after taking Maria hostage on a train, Alphard reveals to Canaan that she thinks that way on purpose because that way she cancels out Canaan's synesthesia and can fight her on equal footing. Even so, Alphard eventually loses her battle with Canaan on top of a speeding train, Canaan offers her a hand as she is hanging off the train by one hand but she refused to accept the help and rather shoots herself multiples times in the arm expressionlessly. Her arm detached and clung to the train while the rest of her flew down the side of the narrow cliff into the ravine. By the end of the series, it is strongly inferred that not only did Alphard survive the drop (sans arm), but continues to commit terrorist acts around the globe as a slightly older Canaan is ordered to hunt her down in Paris as the last episode ends.
