The Doctor is the player character of Arknights and one of the two protagonists of the Main Theme alongside Amiya.


Not much is currently known about the Doctor, other than the fact that they have a doctorate in neurology[2], they're a workaholic[3] had extensively researched Oripathy prior to the events of Arknights. Despite their title, the Doctor is seen to be an excellent field commander, evidenced by their impressive record of commanding Rhodes Island operators in the conflict against Reunion.

Unlike most Terran Ancients, the Doctor lacks any visible animal traits, leaving their race a mystery.

Prior to their amnesia, the Doctor was a member of Babel, R.I.'s predecessor, as one of their key figures; and had more-or-less the same role as they presently have: a tactician and a researcher. The doctor during his days in babel was reguarded as a inhuman figure above everyone, believed by Ines and Hoederer to be much like a chess master who is in control of the whole war.[4]

Adding to they're intimidating figure and reputation, elite operator Scout noted how in the doctor's eyes everyone sees nothing but victory, but he sees nothing. He wished the doctor to not lead another battle and to not have anything to do with Rhodes Island as to not be forged in the flames of war yet again, despite noting that it will lead RI to a golden age.[5]

The Doctor is also believed to have been involved in some way or form in the death of Babel's leader, Theresa, in the most recent civil war in Kazdel. During the decapitating strike operation the doctor is believed by Kal'tsit and W to have leaked the location of Theresa leading to her demise which caused both of them to begin hating them; had it not been for Theresa's wish to ensure the Doctor's safety, Kal'tsit would have already killed them to avenge her death. This is the root cause for Kal'tsit's resentment of the Doctor throughout the Main Story, although she has stated that they mutually did not trust each other prior to this.[6]

The Doctor also acts as a teacher to Ifrit[7] and Projekt Red.

Main Theme


The Doctor, currently healing in the Chernobog Sarcophagus, is rescued by a Rhodes Island extraction team, headed by Amiya. Upon rescue, Rhodes Island discovers that the Doctor is amnesiac; they are unable to remember anything prior to that moment, including their name. After a moment of shock, Amiya quickly recuperates after being told that they are under attack. Amiya then asks the Doctor to take command of their forces, albeit reluctantly due to their aforementioned amnesia. The Doctor is proven to still retain his commandeering skills acutely; they defeat the attackers, who are subsequently revealed to be members of the Reunion Movement.

As the extraction team moves throughout the city, currently in chaos due to the inability of the Ursus soldiers to contain the influx of Reunion members, in an attempt to escape. As the group progresses, they meet with an unknown figure, who expresses their desire for all Chernobogians to die. Narrowly escaping, they rendezvous with Ace, who recognizes the Doctor, and alludes to the "good ol' days," to which the latter expresses confusion. Amiya explains to Ace that the Doctor has lost their memory, and despite being unable to recall past events, their tactical abilities are just as sharp as before. Ace accepts this truth quickly and asks the Doctor for further orders.
