Talion Drake, a tall mercenary of the Northern Jaegers from North Ambria, has short blonde hair streaked with bright violet and distinctive mint-blue eyes. His standard dark green combat uniform features blue and white armor plates on the chest, arms, and boots. For missions, he dons a black sleeveless jacket with an upturned collar, black leather trousers, and a chain at his waist. He wields twin spiked gauntlets, each bearing three spikes, as his primary close-quarters weapons.

Initially serious, straightforward, and deeply loyal to his corps and homeland, Talion displayed a mild-mannered and considerate nature that others sometimes exploited. His commitment to duty remained absolute. However, discovering critical truths—Lavian Winslet's link to Vlad Winslet, Martin S. Robinson's role in the Jaegers' raid on Celdic during the Erebonian Civil War, and how the Erebonia mission provided grounds for imperial reparations against North Ambria—catalyzed his transformation. He joined Jayna Storm's conspiracy.

Aligning with Jayna led Talion to seemingly betray former comrades, most notably shooting Lavian when she stole an Archaism control device from Rogan Mugart. This act was later revealed as a calculated ruse to aid her escape. His demeanor grew increasingly unstable, marked by sinister expressions, especially during the Empire's invasion of North Ambria. His involvement with Jayna's conspiracy masked his true objective: assassinating her. In the climax, he killed Jayna, halting her destructive plans, and collaborated with Lavian to rescue recruits and neutralize a curse she orchestrated.

Talion's combat proficiency centers on leveraging his physical strength and gauntlets in close-quarters. His Jaeger role involved high-stakes operations, including the Erebonia infiltration mission to investigate Rean Schwarzer. His actions during Rogan Mugart's parliamentary coup in North Ambria further demonstrated his complex allegiance as he assisted Lavian despite outward appearances of betrayal.
