Dinosaur King
Dinosaur King

A former second species of Acrocanthosaurus, A. altispinax, was renamed Becklespinax. While it is likely carcharodontosaurid, some scientists think it could instead be part of the more basal (primitive) Allosauridae.

Dinosaur King[]

Acrocanthosaurus' card was activated on Devon Island in Volcanic Panic when its Card Capsule got tossed into a cooking fire. It wandered around the nearby resort causing trouble before swimming to the dormant Mt. Devon volcano island to find the fossils of his mate and child (who are also seen in a flashback). When Max came too close to the fossils, Acrocanthosaurus attacked him, forcing him to summon Chomp to battle back. However, Acrocanthosaurus proved to be a strong dinosaur, easily knocking Chomp to the ground. Chomp then used Lightning Strike against Acrocanthosaurus, nearly defeating him, but he managed to stand up. Right when Chomp tried to finish him off, Terry suddenly charged into the battle and quickly defeated Chomp with his tail, using Volcano Burst to defeat Acrocanthosaurus. Dr. Taylor made the D-Team abandon the card, thinking that Mt. Devon was erupting, only to discover too late that the eruptions were actually only happening in the Battlefield, allowing Ursula to claim the card.

In the next episode, Acrocanthosaurus was turned into Alpha Acrocanthosaurus (a name never actually used onscreen, at least in the dub) by Dr. Z with his Super Alpha Controller. This alteration caused him to have searing-hot skin and be able to breathe fire without the use of a Move Card. He was summoned near the outskirts of the D-Team's home town to steal back their dinosaur cards. However, his Super Alpha Ball control device malfunctioned and he went on a rampage, causing a gas station to explode by simply walking near it and setting fire to everything, starting to head towards the town. He easily defeated Paris and Chomp, his skin being untouchable. Then, (temporarily) overcoming his fear of water, Ace used Cyclone to suck up sea water and form a "Hurricane" attack, defeating Alpha Acrocanthosaurus. His card was reclaimed by Max.

Another Acrocanthosaurus was seen at the Alpha Gang's amusement park in Carnival of Chaos, but like all the other dinosaurs, its control device failed due to a lack of food and it went on a rampage. It returned to its card when Ace briefly fought it and knocked the device off. A possibly animatronic chibi-looking Acrocanthosaurus also appeared in the tunnel boat ride.

A pair of Acrocanthosaurus appeared in Max's Mesozoic dream in Metal Imbalance.

Perhaps the original Acrocanthosaurus appeared in a flashback during Tricks of the Traitor, Dr. Z having it fight an Ampelosaurus for his amusement.

Mesozoic Meltdown[]

Another Acrocanthosaurus was kept on board the Space Pirates' ship. In Desert Heat, it and several other dinosaurs were released by Dr. Drake to distract the Gel Jark guards and allow the D-Teams' kidnapped parents to escape (briefly).

Character Design[]


Like most large carnivores, Acrocanthosaurus was a rather aggressive dinosaur, but it also had a protective side because the reason he fought the D-Team was only to protect his family's fossils. Even without a Move Card, he proved to be a powerful opponent for Chomp and was also a good swimmer.

Later, however, when Dr. Z turned him into an Alpha Dinosaur, Acrocanthosaurus' personality changed, his aggressiveness increased and he seemed only interested in chaos and destruction. Like Ed and Dr. Taylor noticed, he seemed to like it when there was fire all around him and that the fire made him stronger. He also tended to underestimate his opponents, as he turned away from Ace, whom he thought was too weak to be worth his attention, which eventually turned out to be his greatest weakness by not giving himself enough time to counterattack.


  • Dr. Taylor's arcade comments:
    • Japanese: 大型の肉食恐竜だ。首とせなかがひれのように高くもり上がっているところがとくちょうだ。
    • English: A large carnivore. It has high spines along its neck and back.
    • Taiwanese: 大型的肉食恐龍,特徵是在脖子與背部的部分有著像鰭一樣的突起物。
  • DS Game Encyclopedia entry: A large carnivore. It has tall spines like a sail down its neck and back.
  • In the arcade, Acrocanthosaurus has the same base roar as Seismosaurus and Pachycephalosaurus, though each of the others are altered slightly.
  • It is the fifth Fossil Card Dinosaur.
  • Along with Tyrannosaurus, Carcharodontosaurus, Torvosaurus, Giganotosaurus, Tarbosaurus, Gorgosaurus, Daspletosaurus, Alioramus, and Yangchuanosaurus, it is one of the available dinosaurs in the Japanese and Taiwanese non-sale Fire Egg card.
  • Acrocanthosaurus' arcade card was the first exclusive dinosaur in 2007, a promo card from the Japanese Sanrio Puroland distributed from July 14 to September 2.
  • It and its Alpha form have the same anime dub roar as some other large non-tyrannosaur theropods (Carcharodontosaurus and the first Mapusaurus), Majungasaurus, and the large sauropods Supersaurus and Brontikens.
  • In the original Japanese version of the anime, the Acrocanthosaurus was coined as a female, while in the English dub, it was changed to male, a regular occurrence in the dub.
  • Although it had been altered into its Alpha form several episodes earlier and never changed back, a regular Acrocanthosaurus appears in Carnival of Chaos under the Alpha Gang's control (but since there is also no explanation as to how the Alpha Gang got all of those dinosaurs in the first place, as at that time the D-Team possessed all but Terry, Spiny, and Tank, this discrepancy is unsurprising).
  • It is the only dinosaur that the Alpha Trio caught and summoned whose Element corresponded to one of their Stones, in his case Fire (Utahraptor, Styracosaurus, and Altirhinus were dinosaurs that only the D-Team could have summoned, so they needed to be put under the Alpha Controller, and Ceratosaurus was reclaimed before the Alpha Gang could summon him; Saurophaganax, Stegosaurus, and Ampelosaurus, however, are dinosaur whose Elements also corresponded to their Stones, but they were caught by Rod and Laura, Helga, and Seth respectively).
  • Acrocanthosaurus is the only Fire Dinosaur in season 1 not to have used a Move Card (although later when he became Alpha Acrocanthosaurus, he could use a fire blast ability just like a Move Card but without an actual card).
    • It is also the only species of anime Fire Dinosaur not to use a Move Card, the first Carcharodontosaurus counting for both.
  • In the manga, despite appearing to have the color patters of one (in shaded line art, at least), it is not confirmed if this Acrocanthosaurus is really a Super Dinosaur, as Goma just calls it "Acrocanthosaurus", as opposed to Baryonyx, which he calls "Super Baryonyx".
