What is the biggest robot in Horizon?

The Colossal Machines of Horizon: Unveiling the Largest Robot

The title of “biggest robot” in the Horizon universe isn’t a simple, uncontested one. While raw power is often associated with size, Horizon’s machines come in various shapes and forms, each serving a specific ecological or combat function. However, if we’re talking purely about physical size and mass, the Tallneck stands out as the undisputed champion across both Horizon Zero Dawn and Horizon Forbidden West. These gentle giants are truly colossal, dwarfing even the formidable Thunderjaws and serving as mobile communication relays. While other machines might be more deadly or pose a greater combat threat, the Tallneck’s sheer scale makes it the largest in the world of Horizon.

Delving Deeper: Size vs. Threat in Horizon’s Robotic Ecosystem

It’s crucial to differentiate between size and combat effectiveness. The Thunderjaw, for instance, is undoubtedly a devastating force on the battlefield, armed to the teeth with disc launchers, machine guns, and a fearsome bite. Similarly, the Deathbringer represents a terrifying mobile war machine designed for pure destruction. And don’t even get started with the Fireclaws/Frostclaws, gigantic bears imbued with elemental power. However, these machines, despite their considerable size and lethality, don’t quite match the sheer vertical scale of a Tallneck.

The Tallneck’s towering height allows it to survey vast stretches of land, acting as a crucial data relay for the GAIA system. Climbing a Tallneck is a central gameplay mechanic, revealing portions of the map and providing valuable information about the surrounding area. Its role is primarily observational and communicative, not combative. While it can defend itself to a limited extent, its strength lies in its ability to transmit data, making it a unique and essential part of the Horizon ecosystem.

In essence, while the Thunderjaw and Deathbringer may be more deadly, the Tallneck reigns supreme in terms of pure physical size, solidifying its position as the largest robot in the Horizon games.

Frequently Asked Questions (FAQs) About Horizon’s Biggest Machines

Here are some frequently asked questions to further clarify the size and roles of the machines within the Horizon universe:

1. How Tall Is a Tallneck?

Tallnecks are estimated to be around 30-40 meters (approximately 98-131 feet) tall. Their impressive height is integral to their function as mobile communication centers.

2. Are There Different Types of Tallnecks?

Yes, there are variations of the Tallneck across the Horizon games. In Horizon Forbidden West, there are more challenging Tallnecks to climb, often requiring the player to solve environmental puzzles or overcome specific machine encounters to reach the top.

3. What Is the Purpose of the Tallneck?

Tallnecks are designed to be mobile communication relays for GAIA, the AI responsible for terraforming the Earth after the Faro Plague. They transmit and receive data, allowing GAIA to monitor the ecosystem and implement necessary adjustments.

4. Can You Fight a Tallneck?

While Tallnecks are not designed for combat, they can defend themselves if attacked. However, engaging a Tallneck directly is generally not advisable, as it is not the intended gameplay mechanic. The goal is to climb them, not destroy them.

5. What Is the Largest Combat Machine?

The Thunderjaw is widely considered the largest and one of the most dangerous combat machines in the Horizon series. Its size, combined with its powerful weaponry, makes it a formidable opponent.

6. How Does the Thunderjaw Compare to the Deathbringer in Size?

While both are massive machines, the Thunderjaw is generally considered larger than the Deathbringer. The Thunderjaw’s T-Rex-like frame gives it a greater overall volume compared to the Deathbringer’s more compact, heavily armored design.

7. What Is the Most Difficult Machine to Defeat in Horizon Zero Dawn?

Many players consider the Thunderjaw or the Stormbird to be the most challenging machines to defeat in Horizon Zero Dawn, due to their powerful attacks, large health pools, and aggressive behavior.

8. What Is the Most Difficult Machine to Defeat in Horizon Forbidden West?

In Horizon Forbidden West, the Slitherfang and the Specter Prime are often cited as the most difficult machines to defeat. Their complex attack patterns, elemental resistances, and ability to deploy support units make them formidable foes.

9. Are There Any Machines Larger Than the Tallneck Mentioned in Lore?

While not directly encountered, some lore elements suggest the existence of even larger machines from the Old World era. The Faro Plague robots, specifically the Titan class, were described as being colossal, eclipsing even the Tallnecks in size and destructive capabilities, but these are only mentioned historically and not seen in the games.

10. What Makes the Thunderjaw So Dangerous?

The Thunderjaw is dangerous due to its sheer firepower and aggressive nature. It is armed with disc launchers, machine guns, and a powerful bite attack, making it capable of dealing massive damage in a short amount of time.

11. How Do Machines Like the Tallneck Fit Into the Horizon Ecosystem?

Machines in Horizon are not simply mindless robots. They play a crucial role in the terraforming and maintenance of the Earth’s ecosystem. Different machines are designed for specific tasks, such as resource gathering, land clearing, and predator control.

12. What Are the Different Machine Classes in Horizon?

Machines are categorized into different classes based on their purpose and behavior. These include: * Acquisition Class: Machines designed for gathering resources (e.g., Grazers, Bristlebacks). * Reconnaissance Class: Machines designed for scouting and data collection (e.g., Watchers, Tallnecks). * Combat Class: Machines designed for direct combat (e.g., Thunderjaws, Stormbirds). * Transport Class: Machines designed for transporting resources (e.g., Behemoths). * Control Class: Machines designed for controlling other machines and systems (e.g., Corruptors, Deathbringers).

13. How Does Aloy Learn to Override Machines?

Aloy learns to override machines using the Override Module she acquires early in Horizon Zero Dawn. This module allows her to reprogram certain machines, turning them into allies or mounts. The ability to override is expanded in Horizon Forbidden West.

14. Can You Ride All Machines That Aloy Overrides?

No, not all overridden machines can be ridden. Aloy can only ride specific machines designed for transportation, such as Chargers, Striders, Broadheads, Bristlebacks, Clawstriders, Sunwings, and Waterwings.

15. What Does the Future Hold for Machines in the Horizon Series?

With Horizon 3 seemingly in the works, the role of machines is likely to evolve further. The threat of Nemesis suggests that we may see new and even more dangerous machines designed to combat Aloy and her allies. The interaction between humans and machines will likely remain a central theme, exploring the ethical implications of artificial intelligence and the balance between technology and nature. We can also expect more insight into the Old World technology through exploration and lore.


Horizon’s world is a complex tapestry woven with threads of technology, nature, and the resilience of humanity. The machines, in all their varied forms and sizes, are integral to this world, playing a crucial role in both its destruction and its eventual rebirth. Whether it’s the towering Tallneck or the ferocious Thunderjaw, each machine contributes to the rich and compelling narrative that makes the Horizon series so captivating. It also presents interesting opportunities to understand how we learn from games in STEM and ecology.
