Dinosaur King

Some scientists consider this dinosaur to be a species of Allosaurus, though there is a strong case for it being a distinct genus.

Move Cards

Magma Blaster
Saurophaganax collects fire in its mouth, then shoots it off as a spinning beam! This is Saurophaganax's original Move.
Fire Scorcher
Saurophaganax forms a fireball in its mouth, the lets it float up and expand into a giant fiery meteor, which descends and decimates anything in its path! The user of this Move also experiences a massive drain of energy, which Saurophaganax was altered to be resistant to. No dinosaur has survived getting hit by this Move even when at full energy, and it can hit several opponents at once, though it has been dodged.

Dinosaur King

Saurophaganax's card, along with Magma Blaster, was activated in Oklahoma, USA, during Dueling Dinos after its Card Capsule was tossed into a hay fire; it chased a herd of cattle thinking they were food. When the Alpha Gang spotted him, Zander summoned Spiny to battle, but he easily knocked Spiny away and used Magma Blaster to defeat him. Saurophaganax rampaged through the nearby town before dueling Max and Chomp "wild western style", ten paces and turn. Chomp used Lightning Strike and Saurophaganax used Magma Blaster, both mostly dodging but still being grazed by the attacks. They battled until Chomp knocked him to the ground, but then Rod and Laura entered the battle with Terry and Tank, knocking him down. Ace and Paris were then summoned to save him, but Terry used Critical Block, summoning the Velociraptors to block their attacks, allowing him to defeat Saurophaganax with Volcano Burst. Max tried to get the cards, but Rod and Laura used their Alpha Scooters to get them first.

Later, in Full Scheme Ahead, Seth experimented on it, altering it to let it use Fire Scorcher without getting its energy drained away in the process. Seth summoned him against Spiny and Tank when he broke ranks with the Alpha Gang after his secret scheming was brought to Dr. Z's attention; they were equally strong, until he used Fire Scorcher, which defeated Spiny and Tank in one hit. Chomp, Ace, and Paris were summoned to stop him next, but he used Fire Scorcher again to defeat them all at once, too.

In the next episode, Saurophaganax was used to fight against Tank, knocking her into a wall. When Ampelosaurus joined the battle and used Aqua Vortex against him, he used Fire Scorcher, defeating them both. After that, he tried to attack the Alpha Gang, but Helga got in the way, letting them escape in an Alpha Jet. She tried to battle Saurophaganax, but he used Fire Scorcher again, blasting her apart. When the Alpha Gang fled to the D-Lab, his Magma Blaster Move card was potentially reclaimed by the D-Team.

In One Final Move, he was summoned to stop the D-Team after they retrieved their Stones. Terry caught him by surprise, pinning him to the ground, but was defeated with Fire Scorcher. Chomp and Ace attacked him with Thunder Bazooka followed by Cyclone, but they had little effect. Saurophaganax used Fire Scorcher again, which Ace barely dodged. Then at Dr. Z's instruction, they slashed their cards at once to make a Fusion Move, Thunder Storm Bazooka, which finally defeated Saurophaganax, allowing Max to reclaim his card.

In Dinosaur War!, Rex gave his cards to Dr. Z who summoned Saurophaganax among the dinosaur army to fight against the Black T-Rex. When Pachycephalosaurus tossed Dr. Z off the flying Backlander, Dr. Taylor caught his Alpha Scanner and took control of him, allowing him to use Magma Blaster as part of the Fusion Move that defeated the Black T-Rex after three hits.

A recolored wild Saurophaganax was briefly seen walking in the Jurassic Period in Bad Deal.

Character Design


In his debut episode, Saurophaganax largely acted like an ordinary animal, following a herd of cows likely because he was hungry and fighting off Spiny when attacked. However, he showed an unusual quirk of understanding and accepting Chomp's challenge to a cowboy duel, indicating he was a fair fighter.

While being used by Seth, he was likely under an influence similar to the Alpha Controller due to Seth's alterations on him, and so did not reflect his previous self. It is unclear if, assuming it present, this was ever reverted.


  • Dr. Taylor's arcade comments:
    • Original: 超大型のアロサウルスのなかまで、するどい歯と手足のツメでえものをおそった。
    • Translation: An ultra-large dinosaur related to Allosaurus, it use its teeth and claws to catch its prey.
  • Although early estimates at Saurophaganax's size claimed it to be up to 50 feet long (as portrayed in Dinosaur King), recent estimates have shown it to be closer to 40-43 feet long.
  • In the arcade, it shares the same base roar as Alioramus but is pitched deeper.
  • If the player 1 used Saurophaganax in Japanese machine, you will see a special image on the screen (see gallery).
  • It is one of the few dinosaurs in the anime to activate or appear in the state or country that its fossils were discovered in, that being Oklahoma.
  • It is one of the few dinosaurs in season 1 that was briefly speculated by the D-Team to be another dinosaur (Allosaurus) before being correctly identified. The others were Suchomimus (thought a Spinosaurus) and Altirhinus (thought an Iguanodon).
  • Although Saurophaganax was altered to be able to withstand using Fire Scorcher, its appearance didn't change, unlike other altered dinosaurs (the other exception being the 3 Velociraptors that Seth also altered).
    • It can be speculated that while Seth made alterations to the Saurophaganax, this was geared more towards its strength than physical appearance.
  • It is the only dinosaur to directly defeat all 6 of the main dinosaurs, though Therizinosaurus defeated five and exhausted Chomp, and Terry also defeated the other five.
  • The only dinosaur Saurophaganax defeated by himself that wasn't a main dinosaur of the D-Team or the Alpha Gang was Ampelosaurus, though he was summoned by the Alpha Gang to attack Saurophaganax.
  • Though the D-Team and Alpha Gang "pooled" their cards to stop Seth, Saurophaganax's cards still likely remained primarily in Alpha Gang possession (minus Dr. Taylor's usage of it with Dr. Z's Alpha Scanner), though in the end all the dinosaur cards were returned to Dr. Ancient and Dr. Cretacia.
  • Saurophaganax was the only Season 1 dinosaur to reappear in the wild in Bad Deal.
  • In its debut and episode 46, Saurophaganax's dub roar was one later given to Black T-Rex, but starting in episode 47, it gained a new roar later used for several other theropods: Torvosaurus, one of the second Mapusaurus's several roars, Afrovenator, Rajasaurus, and Gigas's later episodes.
    • Though almost lining up, this roar change comes one episode after his alteration was revealed, which could otherwise have been pegged as an explanation.
  • The model of Saurophaganax in the DS game has an error with his tongue, which sticks out of the mouth under the chin, resulting it looking like a horn or a spike that the rest of the Saurophaganax models do not have. This is a common glitch in the DS game, like the spine ridge of the Daspletosaurus that separates from the neck sometimes. A possible explanation for this glitch is that the tongue was attached to the upper jaw instead of being attached to the lower jaw by error, although it's currently unknown.
