A Terrible Lizards tier list for all four creatures plus Dennis, ranked by chase pressure, route impact and counterplay, with the counter for each tier.
Terrible Lizards Tier List: Every Creature Ranked
Quick answer: there is no playable dinosaur roster and no combat in Terrible Lizards, so a tier list has to rank the creatures as encounters. On that basis, the Allo is S tier for pressure, the Bronto and Pterry are A tier for how much they change your route, the Hybrid is B tier as a first-chapter teacher, and Dennis is the final-chapter special case.
This is a ranking of threat and design, not damage numbers. None of the creatures has a health bar, and none can be killed. The all monsters guide is the index if you want behaviour notes without the ranking.
How this tier list is ranked
Four criteria decide each placement:
- Chase pressure. How quickly the creature turns a mistake into a failed route.
- Route impact. How much of the level layout changes because the creature is there.
- Readability. Whether a new player can understand the tell before the punishment.
- Counterplay. Whether there is a skill-based answer beyond running in a straight line.
A creature that is scary but fair can rank above one that is simply annoying. A scripted set piece ranks below a creature that can appear in more than one room.
Terrible Lizards tier list
| Tier | Creature | Chapter | Why it lands here |
|---|---|---|---|
| S | Allo | Chapter 3 | Fast, vertical, punishes hesitation; the best chase in the game |
| A | Bronto | Chapter 2 | Controls open ground and forces raised routes |
| A | Pterry | Later chapters | Attacks from above and punishes floor-only routing |
| B | Hybrid | Chapter 1 | Strong teaching encounter, but more scripted |
| Final | Dennis | Chapter 4 | Story set piece rather than a repeatable chase |
S tier: Allo
The Allo is the creature that most changes how you move. It is fast, it uses vertical space, and it forces you to commit to a route instead of waiting for a safe opening. The counter is to break the charge and take the high line, not to outrun it on flat ground.
What makes it S tier is not raw speed. It is the combination of speed and level design. Chapter 3 gives the Allo rooms with multiple levels, so the encounter is a routing test rather than a sprint. The Allosaurus file covers the charge timing and the safe platforms.
A tier: Bronto
The Bronto is slow, but it owns open ground. It turns the middle chapter into a climb: stay above it, use raised walkways, and never treat a wide room as a straight line. The counter is verticality.
It ranks below the Allo because it is easier to read. You can see the Bronto coming, and the safe route is usually obvious once you look up. It ranks above the Hybrid because it affects more of the map. The Brontosaurus file has the route notes.
A tier: Pterry
Pterry is the aerial pressure creature. It punishes the habit of watching only the floor, and it makes open-air sections feel exposed. The counter is cover and ceilings: put geometry between you and the air, and do not cross a gap just because the ground route looks clear.
It is A tier rather than S because its appearances are more localized. When Pterry is active, it dominates the room; when it is not, the route relaxes. That is a different kind of threat from the Allo, which can turn any multi-level space into a chase.
B tier: Hybrid
The Hybrid is the first real monster and the best teacher. It stalks, it closes distance while you solve a puzzle, and it punishes standing in a doorway. The counter is line of sight: put a wall between you and it, and it loses you.
It sits in B tier because it is the most scripted of the four. That is not a criticism. A first chapter needs a creature that teaches the rules without overwhelming the player. The Hybrid file covers the design history and every appearance.
Final: Dennis
Dennis is the Dilophosaurus character tied to the ending, and the final chapter treats him as a story set piece rather than a repeatable chase. He is not ranked against the other four because the encounter is doing a different job. The Dennis file explains what is confirmed and what the game leaves open.
Best creature for new players
The Hybrid is the best first encounter because it teaches line of sight in a controlled space. The Bronto is the best second lesson because it teaches vertical routing. The Allo is the exam.
If you are struggling, do not try to rank the creatures by speed. Rank them by the habit they punish:
- Hybrid: standing still in open rooms.
- Bronto: crossing open ground at ground level.
- Allo: hesitating at the start of a charge.
- Pterry: watching the floor instead of the air.
Is there a best dinosaur to play as?
No. Terrible Lizards is a first-person horror parkour game with no playable dinosaur mode, no creature selection and no combat. You play Jordan, and the dinosaurs are pursuers. Any list that presents a "best dinosaur build" is not describing this game.
The closest thing to a roster is the Paleo Pals collection: Benji, Alistair, Stephanie, Dennis and Pterry. Those are story characters and collectible talk boxes, not playable fighters. The Paleo Pals guide explains how to find them.
How the tiers change in New Game Plus
New Game Plus adds modifiers rather than new creatures. The four amber sets unlock the modifiers, and the encounters stay the same while the pressure changes. A creature that was manageable on a first run can become a route-ending problem when a modifier removes your safety net.
The tier order stays broadly the same because the counters do not change. What changes is the cost of a mistake. The New Game Plus guide covers the modifiers and what each one alters.
A tier list is a summary. The useful skill is recognising the audio and animation tell for each creature, because that is what gives you the extra second to commit to a route.
FAQ
Is there a Terrible Lizards tier list for playable dinosaurs? No. The game has no playable dinosaur roster.
Which creature is the hardest? The Allo is the most demanding repeatable chase. Dennis is the most scripted final encounter.
Can you kill the dinosaurs? No. There are no weapons and no health bars. Running, climbing and hiding are the only answers.
Which creature is the best designed? The Allo has the best chase design; the Hybrid has the best teaching design. They are good at different jobs.
Does the tier list change with difficulty? There is no difficulty setting. Accessibility options can reduce chase pressure, which changes the experience but not the creature order.
Bottom line
Rank the creatures by the habit they punish, not by size. The Hybrid teaches line of sight, the Bronto teaches verticality, the Allo tests commitment, and Pterry tests air awareness. That is a better tier list than any damage ranking, because Terrible Lizards was never a combat game.
