Subnautica 2 Leviathans List: All New Leviathans
Subnautica 2 has a new Leviathan roster built for a different alien ocean, with confirmed and teased creatures including the Collector Leviathan, Deepwing Brooder Leviathan, Unknown Clam Leviathan, and Unknown Flying Leviathan. Early Access details are still developing, so this list separates confirmed names, trailer shown creatures, and size details that are still forthcoming.

Subnautica 2 All Leviathans List
The current Subnautica 2 all Leviathans list includes the Collector Leviathan, Deepwing Brooder Leviathan, Unknown Clam Leviathan, and Unknown Flying Leviathan. These are the main new Leviathan class creatures appearing across current Early Access coverage, trailers, and developer material.
The important detail is that Subnautica 2 is still in Early Access, so the Leviathan list is not final. Some creatures have clearer information than others. The Collector Leviathan has the strongest official breakdown, while the Deepwing Brooder, Unknown Clam, and Unknown Flying Leviathan are still waiting on more complete in game details.
| Leviathan | Status | Threat Type | Main Detail |
|---|---|---|---|
| Collector Leviathan | Confirmed | Hostile active predator | A massive squid like Leviathan built around reaction, pursuit, and aggressive behavior. |
| Deepwing Brooder Leviathan | Confirmed or teased in current coverage | Unknown large fauna | A new Leviathan with limited public behavior details so far. |
| Unknown Clam Leviathan | Trailer shown | Stationary trap style threat | A giant clam like creature that appears dangerous near its mouth. |
| Unknown Flying Leviathan | Trailer shown | Unknown airborne giant fauna | Large flying creatures seen above the world, with behavior not fully confirmed yet. |
This makes the current Subnautica 2 Leviathans list different from a normal enemy list. It includes active predators, stationary hazards, and giant fauna that may not all behave like traditional underwater chase monsters. That is good for the game, honestly. The ocean is more interesting when every huge creature is not just a Reaper with a new haircut.
Confirmed Vs Teased Leviathans In Subnautica 2
The clearest confirmed Subnautica 2 Leviathan is the Collector Leviathan, while the Deepwing Brooder, Unknown Clam, and Unknown Flying Leviathan are better treated as known or teased Leviathan entries until more final scan data and behavior details are available.
This distinction matters because players searching for all new Leviathans want a complete list, but Subnautica 2 does not have the same kind of stable creature database yet that older Subnautica games have. Early Access creature lists can shift as updates add scans, names, biomes, and behavior changes.
| Category | Creatures | How To Read It |
|---|---|---|
| Most clearly confirmed | Collector Leviathan | This is the new Leviathan with the strongest official developer focus. |
| Known current Leviathan entries | Deepwing Brooder Leviathan, Unknown Clam Leviathan, Unknown Flying Leviathan | These appear in current coverage, but need more final in game detail. |
| Not returning as normal threats | Reaper, Ghost, Sea Dragon, Shadow Leviathan | Older Leviathans are not expected to roam Subnautica 2’s new planet. |
That is the cleanest way to handle the current roster without making the guide look outdated later. The page can rank and explain the creatures now, while leaving room for new details as Early Access expands.
Collector Leviathan
The Collector Leviathan is the main confirmed new predator Leviathan in Subnautica 2 and one of the biggest active threats players should expect in deep open water.
The Collector has a squid like shape and is designed to feel different from older Subnautica Leviathans. Instead of copying the Reaper style body plan, it leans into tentacles, grabbing behavior, and reactive movement. That makes it one of the most important new creatures in Subnautica 2’s ocean.
The biggest thing to know is that the Collector is not only background horror. It is built to react to the player. Its threat comes from active pursuit, mood cues, and the ability to pressure the player once it has noticed them.
| Collector Leviathan Detail | Info |
|---|---|
| Creature type | Hostile Leviathan predator |
| Design style | Squid like, tentacled, reactive |
| Threat style | Active pursuit and player reaction |
| Best response | Create distance and leave the area instead of hovering near it. |
The Collector is the Leviathan that best captures Subnautica 2’s new threat design. It is big, hostile, and reactive enough to make the ocean feel unsafe without needing to reuse the old Reaper formula. Terrible for the player, great for everyone who bought this game to be emotionally bullied by fish.
Deepwing Brooder Leviathan
The Deepwing Brooder Leviathan is one of the known new Leviathan entries in Subnautica 2, but its full behavior and danger level are not as clearly documented as the Collector Leviathan yet.
The name suggests a creature built around brooding, nesting, or offspring behavior, but the safest current guide wording is to treat it as a known large Leviathan class creature with details still developing. It belongs on the all Leviathans list, but it should not be oversold as a fully explained predator until more stable in game information is available.
| Deepwing Brooder Detail | Info |
|---|---|
| Creature type | New Leviathan class creature |
| Known status | Listed in current Leviathan coverage |
| Threat style | Not fully confirmed yet |
| Best response | Treat as a major creature, but wait for clearer scan and behavior details. |
The Deepwing Brooder is worth watching because Subnautica creatures are usually more interesting when they have a role beyond “large mouth with poor manners.” If future updates confirm nesting behavior, rare encounters, or unique biome rules, this could become one of the more memorable Subnautica 2 Leviathans.
Unknown Clam Leviathan
The Unknown Clam Leviathan is a giant stationary creature shown in Subnautica 2 footage, and it appears to work more like a living trap than a roaming predator.
This creature is important because it changes what a Leviathan encounter can be. A normal predator chases the player. A clam style Leviathan turns the environment itself into the danger. That makes positioning more important than speed.
The current read is that the Unknown Clam Leviathan is likely most dangerous when the player gets directly into or near its mouth area. Away from that danger zone, it appears less aggressive than something like the Collector, though final behavior details may change as more in game information becomes available.
| Unknown Clam Detail | Info |
|---|---|
| Creature type | Stationary Leviathan style organism |
| Design style | Giant clam like creature |
| Threat style | Likely trap based around mouth range |
| Best response | Avoid swimming into the mouth or trigger area. |
This is the kind of Leviathan that punishes curiosity more than panic. It may not chase across the biome, but swimming straight into the obvious giant mouth is still a bold strategy. Not a good one, but bold.
Unknown Flying Leviathan
The Unknown Flying Leviathan refers to giant airborne creatures seen in Subnautica 2 footage, with their final name, behavior, and danger level still unconfirmed.
These creatures matter because they show Subnautica 2 is pushing Leviathan scale outside the water. The original games made the deep ocean terrifying. Subnautica 2 appears to be using surface and sky scale too, which gives the world a much bigger feeling.
Current footage makes the flying Leviathans look less immediately hostile than the Collector, but that should not be treated as final. They may be peaceful giants, environmental creatures, or future biome specific fauna with a larger role.
| Unknown Flying Leviathan Detail | Info |
|---|---|
| Creature type | Giant flying Leviathan style fauna |
| Known status | Trailer shown |
| Threat style | Unknown |
| Best response | Track future updates for name, scan data, and behavior. |
The flying Leviathans are one of the biggest reasons this guide should stay flexible. They are clearly part of the all new Leviathans conversation, but the exact role is still not nailed down enough to treat them like normal hostile sea monsters.
Are Returning Leviathans In Subnautica 2
Returning Leviathans from Subnautica and Below Zero are not expected to appear as normal living threats in Subnautica 2 because the game takes place on a different planet.
That means Reaper Leviathans, Ghost Leviathans, Sea Dragon Leviathans, and Shadow Leviathans should not be expected as standard roaming enemies. Subnautica 2 is building a new ecosystem instead of dropping the old monsters into a new map.
The Reaper can still show up as a reference or decoration, but that is not the same as a returning hostile creature. A statue of a Reaper is a cute nod. A real Reaper behind the base is a tax audit with teeth.
| Old Leviathan | Expected As A Living Threat? |
|---|---|
| Reaper Leviathan | No, but references or decorations may exist. |
| Ghost Leviathan | No confirmed return as a roaming creature. |
| Sea Dragon Leviathan | No confirmed return as a roaming creature. |
| Shadow Leviathan | No confirmed return as a roaming creature. |
This is better for Subnautica 2 long term. The new planet needs its own food chain, its own rules, and its own creatures that make players regret swimming confidently into dark water.
Subnautica 2 Leviathan Danger And Behavior
The most dangerous Subnautica 2 Leviathan right now is likely the Collector Leviathan because it is the clearest active predator with confirmed hostile behavior.
That said, danger is not only about size. The Unknown Clam Leviathan could be deadly if players enter its mouth area. The flying Leviathans may be peaceful or may have behavior not fully shown yet. The Deepwing Brooder needs more stable details before it can be ranked cleanly.
| Danger Rank | Leviathan | Why It Ranks There |
|---|---|---|
| 1 | Collector Leviathan | Best documented hostile Leviathan with active pursuit behavior. |
| 2 | Unknown Clam Leviathan | Likely dangerous when the player enters its mouth or trigger zone. |
| 3 | Deepwing Brooder Leviathan | Major creature, but full danger level is not clearly confirmed yet. |
| 4 | Unknown Flying Leviathan | Large creature, but hostile behavior is not confirmed. |
This ranking is based on practical survival risk, not raw size. A smaller aggressive predator is more dangerous than a huge passive creature. Subnautica has always understood this. The fish do not need to be the biggest thing in the ocean to ruin the evening.
How To Prepare For Leviathans In Subnautica 2
The best way to prepare for Leviathans in Subnautica 2 is to upgrade oxygen, unlock key crafting tools, keep landmarks enabled, and avoid pushing into deep open water without a clear route back.
Leviathans punish bad planning. Getting close to one while low on oxygen, lost, and carrying weak gear turns exploration into a very short horror documentary.
| Preparation | Why It Helps |
|---|---|
| Upgrade air tanks | More oxygen gives more time to scan, escape, and recover. |
| Keep landmark signals enabled | Deep water is easier to survive when the route back is clear. |
| Build key crafting stations | Better tools and processed materials support safer exploration. |
| Do not scan at low oxygen | Scanning near a Leviathan takes time and can easily turn into panic. |
| Leave early | Testing attack range usually means becoming the test result. |
For crafting progression that supports safer exploration, the Subnautica 2 Titanium Ingots guide covers how to unlock the Processor and make a key material used for stronger gear progression.
Subnautica 2 Leviathan Sizes
Exact Subnautica 2 Leviathan sizes have not been fully confirmed for the current roster yet. Older Subnautica games have more documented Leviathan size estimates, but those numbers should not be copied over to Subnautica 2’s new creatures.
For now, size details are best treated as forthcoming. The Collector Leviathan is the clearest massive active predator, while the Deepwing Brooder, Unknown Clam Leviathan, and Unknown Flying Leviathans are clearly giant fauna with exact measurements still waiting on stronger in game confirmation.
This section will make more sense once Subnautica 2 has stable creature scans, official measurements, or final database entries. Until then, any exact size chart for the new Leviathans would be more guesswork than guide info, and that is not worth putting on the page.
Final Blurb
The Subnautica 2 all Leviathans list currently includes the Collector Leviathan, Deepwing Brooder Leviathan, Unknown Clam Leviathan, and Unknown Flying Leviathan. The Collector is the clearest confirmed hostile predator, while the others are known or teased Leviathan class creatures that still need more final in game detail.
For players searching Subnautica 2 Leviathans sizes, the honest answer is that exact measurements are still forthcoming. The guide should track the new Leviathans by name, behavior, danger level, and confirmed status first, then add size numbers only once the game or official details gives reliable measurements. The ocean is already terrifying enough without fake ruler math.
