Varis appeared to be a man of average height and build, with short blond hair which he kept parted down the middle and a pronounced chin. He wore the standard Scout Regiment uniform when stationed on Paradis, while switching to the darker Scouts' uniform for the raid on Liberio.
After transforming into a Pure Titan, Varis grows 7 - 10 meters and keeps most of his human traits. It has more prominent cheek bones and has a fixed scowl on it's face.
Varis was a very loyal and trusted member of the Scout Regiment, being one of the few members trusted to help Levi Ackermann guard Zeke Jaeger, and remaining loyal to his superiors even after other soldiers defected to become members of the Jaegerists.
Varis is among the soldiers that take part in the attack on Liberio. After successfully recovering Eren Jaeger, the Scouts make their retreat to Paradis using an airship. Varis is one of the soldiers who accompany Levi to discipline Eren, holding the man at gunpoint while Levi beats him.
Varis is among the soldiers chosen to help Levi guard Zeke Jaeger in a Titan Forest away from Paradis's populace. Despite Levi's misgivings, he and the other Scouts manage to convince the captain to allow them to drink Marleyan wine while guarding Zeke.
Over the course of a month, the soldiers continue guarding Zeke until Varis receives word that a terrorist cell led by Eren has assassinated Dhalis Zachary, and that they are demanding to be brought to Zeke's location. He brings the news to Levi, as well as the news that Dot Pyxis has a plan to capture Eren while the Jaegerists are en route to Zeke's location and pass his powers on to someone else.
Despite Varis's protests, Levi decides to instead have Zeke eaten so that he can no longer pose as a threat to them, and orders Varis to inform Pyxis of the plan. However, as Varis is leaving Zeke uses his scream to activate his spinal fluid which had been laced in the wine the soldiers had been drinking, turning Varis and the other soldiers (except Levi) into Pure Titans. Zeke orders the newly created Pure Titans to kill Levi, but they are all killed by the captain in short order.
