The following dinosaurs are altered in the anime: Alpha Acrocanthosaurus, Black Tyrannosaurus, Gigas, Armatus, and Maximus. Saurophaganax was altered to withstand using Fire Scorcher, and the Velociraptor dinosaur card was merged into a triangular card with two Moves.
Gigas, Armatus, and Maximus belong to the Spectral Space Pirates. Alpha Acrocanthosaurus, Velociraptor, and Saurophaganax belong to the Alpha Gang (the last two to Seth), and Black Tyrannosaurus was created by Seth of his own accord.
There are also altered forms of the six main dinosaurs, which only appear in the arcade and DS Game.
There are several main categories of altered dinosaurs: Super, Alpha, and Black. (Though altered, Gigas, Armatus, and Maximus don't fit into any of these categories. They were altered specifically to handle the Space Pirates' upgraded Spectral Armor.)
Super Dinosaurs only appear in the arcade and DS games (called "Awakened" in the DS). There are a standard 6 Super Dinosaurs per Element, with the main dinosaurs' Super forms (differing from their species' forms in stats alone) making the count 7 each, and with Super Eocarcharia and Super Therizinosaurus being 'exceptions'.
With the exception of Super Eocarcharia, Super Dinosaurs are all colored after their Element in patterns unique to each dinosaur: Super Lightning Dinosaurs are yellow and grayish black; Super Wind Dinosaurs are light blue and grayish black; Super Grass Dinosaurs are dark and light green, and have a yellow strip down their backs; Super Fire Dinosaurs are orange, yellow, and grayish black; Super Water Dinosaurs are blue, light blue, and white; Super Earth Dinosaurs are dark and light purple; and the only Super Secret Dinosaur, Super Therizinosaurus, is ringed with black "Charlie Brown-style" zig-zags separated by a light rainbow-like gradient. Super Eocarcharia is black and covered with purple veins. There is no noticeable size difference between Super Dinosaurs and their unaltered forms.
Arcade Super Dinosaurs are "upgraded" forms of regular dinosaurs on the reverse sides of special cards of the Japanese-only Kakushin editions, with double the Technique and Attack stats for each Sign. At the beginning of every round (except the first round) when the dinosaurs are still walking into position, Super-capable dinosaurs (with the same stats and appearances as their ordinary versions) show a colored ring in the Super Dinosaur symbol over the Signs, which quickly empties and disappears. If you press all 3 move buttons at once while the ring is still visible, the dinosaur becomes its Super form, triggering the arcade's background music to change to a high-energy horn solo. However, the dinosaur only stays its Super Form for one Rock-Paper-Scissors match-up (not counting any ties). Immediately after an attack is made, the Super Dinosaur reverts to its regular form (the music ending) and loses half its current health bar whether it won or not, making it best to wait until one has less than half health before using. There seems to either be 3+ turns of cooldown before the Super change option presents itself again, or it can only be used once (dinosaurs in known videos don't last very long after going Super to confirm); the option doesn't seem to present itself in any round of a standard 2v2 match (or tournament) when a new dinosaur has just entered the fight (for you or your opponent), though 2v2 tag team matches don't seem to have this block.
Alpha Dinosaurs are in the arcade and DS games, the TCG, and one, Alpha Acrocanthosaurus, appears in the anime. There are 4 Alpha Dinosaurs per Element, with two from the arcade game and two being TCG-only. Fire breaks the pattern with three arcade forms and only one TCG-only. There are no Alpha Secret Dinosaurs known at this time. The term "Super Alpha Dinosaur" (arcade only) seems to apply to the dinosaurs that had a Strength level of 1400 in their original forms (Allosaurus: 1400 -> Super Alpha Allosaurus: 1800); there is therefore usually 1 regular Alpha and 1 Super Alpha Dinosaur per Element in the arcade.
Alpha Dinosaurs in the arcade and DS are all colored various shades of gray, yellow, pink, and/or dark purple. The TCG-only Alpha Dinosaurs tend to follow a different pattern, being a combination of any shade of purple, pink, red, and/or yellow. Regardless, all are controlled by the Alpha Gang, which is where they take their name from. Acrocanthosaurus's Alpha Form is commented by Ed to be slightly bigger than it's unaltered form, and it can also breath fire without a Move Card. It is unconfirmed if any other Alpha Dinosaurs possess similar elemental abilities.
Alpha Dinosaurs appear in the arcade game as separate entities from their regular forms, battling all the time as Alpha Dinosaurs. They are also distinct cards in the TCG, but the anime's Alpha Acrocanthosaurus was altered from the original Acrocanthosaurus.
|p · e · t||Alpha Dinosaurs|
|Alpha:||Gorgosaurus/Alpha · Irritator/Alpha · Einiosaurus/Alpha · Wuerhosaurus/Alpha · Ouranosaurus/Alpha · Dilophosaurus/Alpha|
|Super Alpha:||Acrocanthosaurus/Alpha · Rajasaurus/Alpha · Suchomimus/Alpha · Chasmosaurus/Alpha · Kentrosaurus/Alpha · Iguanodon/Alpha · Allosaurus/Alpha|

Black Dinosaurs are far less numerous, with only 6 Black Dinosaurs stretched across the arcade game, anime, and TCG. The Black T-Rex is the only Black Dinosaur to currently appear outside the TCG (arcade and anime). They are black or gray, with sparse patches and/or veins of their elemental color or one similar to it across their bodies.
In the anime, the Black T-Rex was resurrected from a fossil by Seth, the others likely having a similar origin implied. They are several times bigger than their unaltered forms, the Black T-Rex in the anime likely being rivaled in size only by the largest sauropods (Apatosaurus, Supersaurus, and Seismosaurus), though it is shown as far smaller than this (but still noticeably larger than a regular Tyrannosaurus) in the arcade. Naturally, they are some of the strongest dinosaurs of all.
Like Alpha Dinosaurs, the arcade Black Tyrannosaurus is separate from its regular form, battling all the time as a Black Dinosaur.
