The full Terrible Lizards voice cast: Kellen Goff as Jordan, Amanda Hufford as Stella, MatPat as Dr. Fellows, plus DJ, Elena and Pterry.
Terrible Lizards Cast: Every Actor and Character
The Terrible Lizards cast is smaller than the game's body count suggests. Six actors are credited on IMDb, and three of them carry most of the runtime: Kellen Goff as Jordan, Amanda Hufford as Stella Banks and Matthew Patrick — MatPat — as Dr. Johnathan Fellows. The rest of the park is filled in by tapes, letters and one very loud pterosaur.
This page lists every credited voice, explains who each actor plays, and settles the question that brought a lot of people here: MatPat is in Terrible Lizards, but he is not the player character. It contains story spoilers for Chapter 4.

The full cast at a glance
| Actor | Character | What you hear |
|---|---|---|
| Kellen Goff | Jordan | The player character's reactions, effort lines and story dialogue |
| Amanda Hufford | Stella Banks | The paleontologist on the headset |
| Matthew Patrick (MatPat) | Dr. Johnathan Fellows | The scientist connected to the underground sabotage |
| Greg Holgate | Pterry | The Paleo Pal pterosaur |
| Sydney Osmon | Dalton Jr. ("DJ") | The missing child |
| Katy Bentz | Elena Coolidge | Dalton's wife and the park's co-founder, heard in letters |
John Gelardi is credited as director. The score is by JT Music, the nerdcore group founded by Gelardi and Christian Ames; the same press release that announced the cast calls the soundtrack "brilliant," which is the closest thing to an official review the game has.
Kellen Goff as Jordan
Jordan is the college student whose car breaks down outside Dalton's Dinos. He is the camera, the hands and the voice the player hears when something with too many teeth comes around the corner. Kellen Goff gives him a performance that starts annoyed and ends exhausted: the jokes get shorter as the park gets deeper.
Goff is known for a long list of animation and horror roles, including Five Nights at Freddy's and My Hero Academia. His Jordan is not a mascot voice or a monster growl. It is a normal twenty-something trying to keep it together, which is exactly what the game needs. If you have played the opening, you have already heard most of his range: complaint, panic, relief, then complaint again.
Amanda Hufford as Stella Banks
Stella is the paleontologist who stays on the headset while Jordan goes underground. She is the game's guide, its exposition delivery system and its only adult voice with a plan. Amanda Hufford plays her as patient but increasingly worried; the performance has to sell clues over a radio without turning into a tutorial voice.
The surname Banks comes from the IMDb credit. In-game dialogue mostly calls her Stella. She is not playable, and she does not appear in the park during the main story. Her role is to keep Jordan moving and to make the park's history personal.
Without Stella, the park is a haunted house. With her, it is a family story. The story explained page collects the information she gives you.
MatPat as Dr. Johnathan Fellows
This is the answer most people want: MatPat voices Dr. Johnathan Fellows, not Jordan. Dr. Fellows is the scientist whose body holds the key Jordan needs in Chapter 4. The character is dead when you find them, so most of the performance is delivered through recordings, notes and the weight of what Fellows did.
That casting is a good joke and a good piece of design. MatPat is famous for explaining lore, and Fellows is the character who created most of the lore Jordan has to survive. The game does not give him a triumphant scene. It gives him a body, a key and a trail of decisions that ruined the park.
Fellows is dead when Jordan reaches them. Taking the key starts the Dennis chase. The Chapter 4 walkthrough covers the sequence without the story detour.
Greg Holgate as Pterry
Pterry is the Paleo Pal pterosaur and the fifth member of the mascot lineup. Greg Holgate — better known online as The Stupendium — voices him. Pterry is the brand's know-it-all showman, which fits both the mascot and the casting: a theatrical voice for a character who exists mostly on signage, merchandise and the park's recorded announcements.
Pterry is also the reason the Paleo Pals are not just four dinosaur suits. The lineup is five characters; only four of them appear as wearable suits in the museum and storage areas. The Paleo Pals page breaks down each mascot and where the suits show up.
Sydney Osmon as DJ
DJ is Dalton and Elena's son, the missing child at the center of the story. Sydney Osmon voices him with a small, careful performance. DJ has been underground for a long time, and the voice sounds like it: quiet, a little flat, more comfortable with Dennis than with the adult who just arrived.
The restraint is the point. DJ does not explain what happened to him. He recognizes Jordan, follows him and recognizes Stella's car at the end. The ending explained page covers what that final scene does and does not confirm.
Katy Bentz as Elena Coolidge
Elena is Dalton's wife, the park's co-founder and DJ's mother. She is heard through letters rather than tapes, and Katy Bentz plays her as the controlled half of the marriage. Dalton's recordings get louder and stranger; Elena's letters get shorter and more careful. Together they tell the story of a family trying to keep a business and a sick child alive at the same time.
Elena is not a puzzle. She is the character who makes the park's decline feel like a family failure rather than a monster attack.
Who is not in the cast
The park's creatures do not have credited voice actors. The Brontosaurus, Allosaurus, Hybrid and the rest are sound design and animation, not performances. Dennis is the exception in spirit: the mascot has a voice in the park's materials, but the underground entity does not speak in the same way. The Dennis page separates the suit from the thing under the park.
Dalton Coolidge, the park's founder, is heard through tapes. He is not listed among the six IMDb cast credits, which is why some cast lists stop at five names. Treat the tapes as a performance without a confirmed credit rather than a missing actor.
Where to hear the cast
The quickest way to hear the whole lineup is to finish the game and watch the credits. If you want to sample the performances first, the opening twenty minutes give you Jordan and Stella, the museum tapes give you Dalton, and the Chapter 4 recordings give you Fellows. Pterry is mostly in the park's branding and the Paleo Pals material, so his lines are easy to miss if you rush through the exhibits.
The game does not have a traditional credits menu on the title screen. The end credits are the reliable in-game source; IMDb is the reliable outside source, and the official press release confirms Goff, Hufford and MatPat by name.
