Zombie apocalypse

Main risks
The main danger for them is not the zombies, but their own character.
Waru might have decided to "joke" by locking Peak in a room with a couple of dead men, confident that he could handle it, but underestimating the scale of the threat.
In a fit of rage, Peak might simply leave Vara alone if he crossed the line at the most inopportune moment.

Waru: Slingshot with poison/noise projectiles, knives. Ranged combat, environmental exploitation, creating noise to distract crowds.

Peak: A heavy wrench, axe, or rebar. Brute force, methodical destruction, a direct breakthrough.

Authority Conflict: Waru would constantly question Pieck's orders, simply to irritate him. In a world where any mistake leads to death, Pieck would quickly lose his patience, which could lead to a serious fight between them right in the middle of an abandoned supermarket.
Specific concern: Despite his hatred, Peak understands that Waru is his only ally. He would rescue the jack from trouble, accompanied by harsh slaps and grunts. Waru, behind the mask of trolling, would stick close to Peak, knowing he is his best guarantee of safety.

Appearance: Green curly hair and the obligatory green spiral glasses he never takes off. He wears a green hoodie.
Personality: A troll, manipulator, and master trickster. Varu loves to bully others (especially Umbrella), pull pranks, and wreak havoc. His arrogance often masks a fear of being weak or unwanted.

Waru (Provocateur and Scout): Waru would likely perceive the onset of the apocalypse as "the greatest show on earth." He would mock the zombies' slowness and set traps not only for the undead but also for other survivors. His job is reconnaissance, but trusting his reports would be dangerous.

Appearance: Purple hair styled into horns, cat-like pupils, and a stern gaze. Wears a leather jacket and chunky boots.
Personality: A natural leader, tough, unsociable, and goal-oriented. Peak hates confinement and strives for freedom at any cost.

Peak (Leader and "Tank"): He would take on the role of primary strategist and fighter. Peak isn't one to panic; he would quickly find transportation (most likely a motorcycle or a fortified van) and melee weapons. His pragmatism would allow the group to survive for a long time, but his irritability would grow with each passing day due to the chaos around him.
