Zombies
Zombies are the most basic form of undead, bodies animated by lingering magic or unnatural force, stripped of thought, purpose, and identity.
They do not act with intent or strategy. Instead, they move forward relentlessly, driven by whatever force sustains them, attacking anything within reach.
Unlike other undead, there is no trace of who they once were. Only the body remains, decaying, unfeeling, and persistent.
Zombie Hulk
A larger, more durable form of zombie, the hulk continues forward even as its body breaks apart. Its strength and resilience make it especially dangerous, not because it is clever, but because it is difficult to stop.
Observations
Zombies are slow, predictable, and seemingly mindless, but their persistence makes them dangerous over time.
What they lack in awareness, they make up for in endurance. They do not retreat, do not hesitate, and do not stop until they are destroyed.
