Move Cards[]

A tornado descends onto Ace, surrounding him with wind and boosting his ramming and throwing power! This is his original Move Card, found with his card, as well as his most-used one. He twice used it to suck up a large amount of water, turning his attack into a "Hurricane" (a giant water tornado).
Ninja Attack
Ace runs forward and creates duplicates of himself, all of which jump up and land around his opponent, running in a circle around them; then, Ace and his duplicates dash from one side to the other, slamming the opponent, the hits quickly becoming faster and faster! It was acquired from the reclaimed card-folio, and was first and often used to defeat Tank when the full D-Team/Alpha Gang teams face each other.
Ace races forward and vanishes in a blur, zooming around his opponent before zipping in and slamming them repeatedly at blinding speed! It was obtained after Allosaurus's defeat, and was only used to defeat Terry and Tank in Santa Saurus!.
Thunder Storm Bazooka (Thunder Bazooka/Cyclone Fusion Move)
Chomp and Ace charge in a line as a wind tunnel forms around them; Chomp leaps and spins like in Thunder Bazooka, gathering electricity and wind around his body before slamming and drilling into their opponent! It was the first-identified true Fusion Move, though not the first attack fusion. It defeated Seth's altered Saurophaganax and was the first attack to break Spectral Armor (Torvosaurus').
Ultimate Wind
While wearing DinoTector Armor, a burst of wind from the ground strengthens Ace, before he runs forward and jumps to create a cone of wind around him, flying forward and ramming into his opponent with it! Provided by Dr. Z along with the Element Boosters, it was first used against Megaraptor and last used against Brontikens.
Biting Wind
With tornadoes raging around Ace, a storm of spinning crescent wind blades shoot out from behind him! Likely provided by Dr. Z, it was only used to blow away the lava from a volcano eruption in Elements of Surprise.
Hurricane Beat
A pair of tornadoes split from around Ace and merge onto his opponent, lifting and suspending them in the air; Ace then jumps over and kicks them repeatedly and rapidly in the face, then flips back and knocks them away with a swing of his tail! It was obtained after defeating Shear's Megaraptor.
Sonic Blast
Ace charges and shoots a swirling burst of wind from his mouth at his opponent, blasting them back! Its first usage showed him blasting into the sky in a tornado before rocketing down again to deliver the attack, but this part seemingly added nothing to the result and was never seen again. It was likely provided by Dr. Z.

DS Stats[]

  • Elemental Attribute: Wind
  • Critical Move: Rock
  • Rarity: 4 star
  • Battle Type: Super Blitz Type
  • Fossil/Move Set: Stone Circle (European Scissors Normal Moves, Scissors Wind Moves, LV28 Cyclone (S))
  • Users:
    • (None, player only)
  • Encyclopedia number: Ex
  • Special Acquisition: For his LV1 card, enter at the Stone Circle Lightning-Grass-Fire-Earth-Water-Water-Lightning-Fire. The same code gives Ace to Rex players and Chomp to Max players.
  • Other: Possibly by a glitch stemming from this fact, Ace learns from Move Lists (Normal and Super) for a Scissors Dinosaur (like Chomp) despite being a Rock Dinosaur, the only time this is known to occur. This leads him being one of the few Dinosaurs whose Rarity-based LV28/31 Super Move does not match his Sign. He is one of the Dinosaurs with the off-pattern stats shared between Anime and Secret Dinosaurs.

Dinosaur King[]

In Battle at the Pyramids, his card, along with Cyclone (and Paris), was found in Alberta, Canada, by Dr. Owen at a fossil dig, and was immediately shipped to the D-Lab. He was first summoned by Rex after teleporting to Egypt to help Max and Chomp fight the Alpha Gang and wild Spinosaurus (now under their control); he managed to defeat Spiny with Cyclone. He was called "Ace" because it means "number one", and he was Rex's first dinosaur. His chibi form was introduced to Mrs. Taylor as a "dog", and he lived in Max's house with Rex.

He becomes the D-Team's second most-used dinosaur after Chomp and managed to defeat a number of dinosaurs throughout the season. He acquired his second Move, Ninja Attack, from the card-folio Jonathan had after retrieving it from the Alpha Gang, and took Mayfly after besting Allosaurus (for one use), being the only D-Team dinosaur to not use a Normal Move.

He is easily the fastest dinosaur of the D-Team and even all main dinosaurs, as seen in Alpha Bets It All by racing Suchomimus and Spiny, and manages to dodge hits from Tail Smash (sometimes) and Shockwave, both of which were so fast to be thought unavoidable, and avoided Mayfly with Ninja Attack. Although he is not as powerful as Chomp, he has beaten his fair share of powerful opponents through strategy like Carcharodontosaurus and Alpha Acrocanthosaurus, both of which had an Element advantage over him, and managed to perform the first Fusion-ish Move, combining Cyclone with a large volume of water.

He is, however, afraid of water, which was shown first in Maui Owie!, where he refused to help Styracosaurus when battling at the beach. In All Fired Up! and Falls Alarm!, he manages to briefly overcome his fear to help Rex and defeat the rampaging dinosaur, but was shown to still have it later in A Kyoto Caper.

In One Final Move, he and Chomp were instructed how to form a Fusion Move by Dr. Z, merging Cyclone and Thunder Bazooka into Thunder Storm Bazooka to defeat Seth's Saurophaganax. In the finale, he was summoned as part of the crowd to help to defeat the Black T. rex, using Cyclone as part of the Super Fusion Move that defeated it after three hits. After that, he and the other dinosaurs were taken back to the future on the Backlander with Rex, the Alpha Gang, and the Ancients

Mesozoic Meltdown[]

…but were forced to return to the present by the attacking Spectral Space Pirates, reuniting Ace and Rex with the D-Team. When the timeship flew uncontrollably to the Late Cretaceous Period trying to follow the Pirates, he was summoned alongside Paris to stop the Alpha Gang from summoning Spiny and Tank to capture wild dinosaurs.

This season, he acquires a total of 4 new Move Cards, three made by Dr. Z to battle the Space Pirates, and Hurricane Beat stolen after defeating Shear's Megaraptor. He and Chomp managed to defeat the first Spectral Armor dinosaur without armor themselves by using Thunder Storm Bazooka. In Dinosaurs of the Caribbean, he first uses his DinoTector Form to battle against Edmontonia, but it takes until a later fight to use Ultimate Wind and beat Megaraptor, the only main dinosaur to have this delay.

Despite not being the star player that Chomp was, again taking second spotlight, in some situations he was shown to be better than Chomp. He defeated Megaraptor and Gojirasaurus, who had nearly defeated Chomp, thanks to his Wind Moves, and he even defeated Lexovisaurus, the only low-rank dinosaur that defeated Chomp this season. He was even able to do well against Secret Dinosaurs: he was fast enough to land a hit on Seth's Cryolophosaurus, though not defeat it, also defeating Shear's Deinonychus trio twice, a feat that had taken all three D-Team dinos against Dr. Z's trio. Still, he was sometimes beaten, falling to Yangchuanosaurus, Anhanguera (summoned by Pachyrhinosaurus), and once to Armatus.

With the other main dinosaurs, he took part in the final battle against the Dark Pterosaur in his DinoTector Armor, using Sonic Blast in a 6-part Fusion Move to punch a hole in it, then in a 3-part combo attack to defeat a powered-up Armatus and Maximus, and using Ultimate Wind in another 3-part combo Move to defeat a powered-up Brontikens. However, because he'd been summoned by Seth's copied Stones to take part, he was forever locked from being summoned as a chibi again, a condition begrudgingly agreed to. He appeared again with Rex in the Mesozoic Forest projection on the damaged Backlander after all the dinosaurs were rescued. He and the other dinosaurs were again taken back to the future, with Rex, the Ancients, and the Alpha Gang, this time on the captured Space Pirate Ship.

Character Design[]


Ace's English and Japanese names are the same, both meaning "number one" for being Rex's first dinosaur, and also generally someone excellent at something.


Ace is a friendly dinosaur, but is also shown to be a little more idiosyncratic than Chomp and Paris, possibly because he is a heroic carnivore. He has a very deep friendship with Rex and also showed great bravery when he attacked Ankylosaurus as a chibi in Dino Snore!, although in this modus he was actually completely unfit to fight.

One of Ace's greatest weaknesses is his great fear of water, even though there were situations where he was willing to briefly overcome it when there was no other way to win. The reasons for Ace's fear of water are never addressed, but it is possible that it is either due to trauma from his past or just a personal dislike.


  • Rex's arcade comments:
    • Original: 鬼のような角がすごくクールな恐竜なんだ。スピードのあるこうげきならエースにまかせて。
    • Translation: The horny horns make him a cool dinosaur. Leave the speed attack to him if you want.
  • DS Game Encyclopedia entry: A dinosaur with cool horns like an ogre. Ace is great at speedy attacks. (Rex)
  • In the English version, Ace's sounds are "voiced" by Eric Stuart, the same man who voices Dr. Z. This is quite obvious in episode 75; when Ace is scared by a dragonfly, he screams and it sounds exactly like Dr. Z.
  • While Ace's main anime dub roar seems to be taken from cougars or similar big cats, the different roars he has while starting to use his Moves certainly are.
  • He is the fastest main dinosaur, with Spiny coming in second (as seen in Alpha Bets It All).
  • Ace was the first main dinosaur of the D-Team to be defeated by the Alpha Gang, in his case by Terry in episode 3 (Chomp had only previously returned to his card from exhaustion after defeating Terry).
  • Ace is afraid of water, only briefly overcoming this fear in All Fired Up! and Falls Alarm! because he needed to to save the day.
  • Ace is the only main dinosaur who was not defeated by a dinosaur of his own Element (although Majungasaurus nearly beat him with Mayfly in Desperately Seeking Spartacus).
    • He also never defeated a dinosaur of the Element weak to his, Grass: he was interrupted by Spiny while fighting Altirhinus, and he only threw Lanzhousaurus into a wall with Cyclone but did not defeat it. Neither was he defeated by a dinosaur of that Element.
  • Ace is the only main dinosaur who never used a Normal or Assist Move Card.
  • He is also the only main dinosaur who didn't use his Ultimate Move against the first dinosaur he faced in his DinoTector Armor.
  • Despite the fact that he isn't as strong as Chomp, he managed to defeat some dinosaurs that beat Chomp (such as Alpha Acrocanthosaurus, Allosaurus, and Lexovisaurus), though he was also defeated by some dinosaurs that Chomp then defeated (such as Megalosaurus, Yangchuanosaurus, and Pachyrhinosaurus).
  • Ace is one of the few dinosaurs whose anime card doesn't match their picture in NagoyaTV.
  • Similar but less extreme than Chomp and Triceratops, the arcade models for Ace and a generic Carnotaurus differ slightly in color, with Ace being a more purple shade and Carnotaurus being more solidly gray. They share models in the DS game, however.
  • Ace is also the only main dinosaur of the D-Team to never defeat the 3 main Alpha Gang dinosaurs at once (Chomp defeated all of them with Electric Charge in Double or Nothing and Paris defeated all of them with Big Foot Assault in The Big Apple Grapple). He was however able to defeat both Terry and Tank with Mayfly in Santa Saurus!.
  • Ace appears at least in chibi form in every episode after his debut except Battle Royale!. Amazing Treasure Race! is the first time he only appears full-size instead of a chibi, except for his brief summoning sequence; The Third Cosmos Stone first sees him full-size with no summoning sequence.
  • Ace and Tank are the only main dinosaurs to directly attack the Space Pirates as chibis: Ace did so in Dinosaurs, Ninjas and Bears! Oh My! when he bit Gabbro's hand.
