Paul Bäumer
Paul is the narrator and the emotional center of the novel. He enlists at nineteen and spends the book watching his classmates die and his own capacity for feeling slowly shut down. His arc isn't growth — it's erosion. By the end, he's alive but barely present.
Stanislaus Katczinsky (Kat)
Kat is the older, experienced soldier who becomes Paul's closest friend and a surrogate father figure. He knows how to find food, read danger, and stay calm. His death is the event that finally empties Paul out completely. Kat represents what competence and decency look like when the war hasn't finished with you yet.
Kantorek
Paul's former schoolteacher, who pushed his students to enlist with patriotic speeches. He appears briefly in person later, drafted himself, and the soldiers treat him with contempt. He represents the civilian world's failure to understand what it sent young men into.
Corporal Himmelstoss
The brutal drill sergeant who torments Paul's group during training. He shows up at the front later, where his cruelty is less useful and his cowardice becomes visible. He's a smaller villain than the war itself, but he shows how authority gets corrupted by power.
Franz Kemmerich
One of Paul's classmates, who dies early after losing his leg to infection. His death is the first major one in the novel, and it sets the tone. His boots, passed from soldier to soldier, become a recurring image of attrition throughout the book.
Albert Kropp
One of Paul's closest classmates and a fellow soldier. He's sharp and skeptical, often voicing the group's disillusionment directly. He loses a leg and is sent to a hospital in Germany, surviving longer than most but facing an uncertain future.
Tjaden
A thin, hungry soldier in Paul's group known for his appetite and his grudge against Himmelstoss. He provides some of the novel's darker humor and represents the ordinary soldier trying to hold onto personality under impossible conditions.
