Dr. Kal'tsit

Dr.Kal'tsit, one of the central figures and most lore-significant characters in the mobile RPG Arknights. • While she appears to be a member of the Feline race, Kal'tsit is actually an artificially sustained immortal being with the codename AMa-10. She was created over 13,000 years ago by a hyper-advanced, extinct precursor civilization to guide and preserve life on the planet Terra. • Kal'tsit does not age normally; if she is killed in battle or dies of physical trauma, her consciousness and body eventually reincarnate/reboot. Because of this, she has personally witnessed thousands of years of Terran history, the rise and collapse of multiple empires, and countless catastrophic wars. • Officially, she acts as the Head of the Medical Department. In practice, alongside the Doctor and Amiya, she is the true strategic and political backbone of the entire Rhodes Island organization. • She acts as a fierce protector and mother figure to Amiya, honoring the dying wish of the former Sarkaz ruler, Theresa. • Kal'tsit has a highly complex, historically tense relationship with the Doctor. Before the Doctor's amnesia, they worked together in an organization called Babel. She harbored deep resentment toward the pre-amnesia Doctor due to their ruthless, cold-blooded tactical methods that often treated people like disposable chess pieces. Over time, she grudgingly learns to trust the current, more empathetic Doctor. • The Community Nickname: Due to her sharp tongue, shared history, and strict attitude toward the Doctor, the Arknights player community affectionately refers to her as the "Ex-Wife". • Despite being categorized as a "Medic" in-game, Kal'tsit is an incredibly powerful combatant. She houses a terrifying, semi-sentient biomechanical creature named Mon3tr inside her spine, which she can summon at will to rip through entire military squads or match the strength of legendary warriors.
