Move Cards[]

Dino Swing
Tank bites the dinosaur's tail and swings them around several times before tossing them away! It was first used against Utahraptor and last used against Ampelosaurus.
Earth Barrier
Chunks of earth fly up when Tank stomps the ground, expanding into a glowing purple crystal dome, protecting her from her opponent! It was only used to defend against Daspletosaurus's Fire Bomb.
Tank stomps the ground, opening up a long narrow crevice that her opponent falls into, which then slams shut! It defeated Daspletosaurus and was also used in the Super Fusion Move against the Black T. rex.
Tail Smash
Tank hits the opponent with her tail! Passed from Terry after he got it from Spiny, it was only used to flip herself right-side up and charge at Fukuisaurus, but she was defeated before reaching it. Many times before she had also made a signature tail-swinging attack similar to Tail Smash, but without the use of a Move Card.
Ultimate Earth
While wearing DinoTector Armor, six large purple crystal chunks stick up around Tank's path, which she charges through, absorbing power and speed as she breaks them, and then slams into her opponent! Provided by Dr. Z along with her Element Booster, it defeated Gabbro's Carcharodontosaurus, but was blocked by Gigas and was never used again.
Quake Saber
A crystal sword forms on Tank's tail to slice her opponent with! This was only used against Genie. It may have been borrowed from Euoplocephalus, newly strengthened by Dr. Z, or taken from Tuojiangosaurus.
Tupuxuara Dive
Tupuxuara flies in and divebombs Tank's opponent! It was only used once to save Zoe from a collapsing bridge and to drive Foolscap away, though where its Tupuxuara is supposed to have come from is unclear.
Spike Arrows
Energy surges across Tank's back and up her tail, and a she shoots a swarm of crystal spikes from her tail club! It was only used as part of the Fusion Move against the Dark Pterosaur. It may have been borrowed from Stegosaurus or newly strengthened by Dr. Z.

Dinosaur King[]

Saichania's card was first activated in Tanks a Lot! in a museum in London by Zander when he accidentally kicked a potted plant to spill on it (the Earth Stone was found there too), and after wandering the museum for a while she was defeated by Terry and captured by the Alpha Gang, having already been named "Tank" by Ursula before she was even caught. She was the second wild dinosaur that became a main dinosaur (the first being Spiny), and was quickly given a more violent personality by Dr. Z with the Alpha Controller.

Out of the dinosaurs that the Alpha Gang has, she is the least-often used. Despite the fact that she wasn't summoned very many times, however, she did defeat a number of dinosaurs she was summoned to fight (unlike Spiny, though many of Tank's victories were against weak, distracted, or previously worn-down opponents, and she suffered an Alpha Gang-signature number of losses). When she was first summoned to battle, she managed to defeat Utahraptor with Dino Swing. This became the Move she used the most often during the series with three episodes, but repeating the Super Fusion Move three times in the finale let Earthquake overtake it with five total season uses. Earth Barrier and Tail Smash (originally Spiny's move, but passed to Terry then Tank) were used only once each (and Tail Smash never hit), though she would often use a non-Move tail swinging attack to a similar effect to Tail Smash. She used Super Moves only once before the finale, in Dance Evolution against Daspletosaurus and Ace. As time went on, she was usually only used alongside one or both of the Alpha Gang's other dinosaurs.

As a chibi, she often curls into a ball and rolls around. In Field of Screams, she is dressed up as a parade float so the Alpha Gang can scout for the dinosaur, and A Miner Disaster displays her uncanny tunneling ability, carving a spacious tunnel in one pass with no debris left behind. However, she can easily be rendered useless and helpless by being flipped onto her back, as seen many times.

She is summoned against the betraying Seth's Saurophaganax alongside Spiny in Full Scheme Ahead, quickly being defeated by Fire Scorcher. After breaking the Alpha Gang out of the garbage chute, she is summoned alongside Ampelosaurus to fight Saurophaganax again in the next episode, but is defeated again. In the finale, she uses Earthquake in the Super Fusion Move against the Black T. rex, helping to defeat it after three hits. In the end, as she'd initially been turned into a card to preserve her species, she and the other dinosaurs are taken back to the future by Rex, the Ancients, and the Alpha Gang…

Mesozoic Meltdown[]

…until the Backlander is forced to return by the attacking Spectral Space Pirates, after which she was confined on board with the rest of the Alpha Gang until the ship was "fixed" and sent careening through time. After Terry failed to capture any dinosaurs in the Cretaceous Period in Alien Parent Trap, the Alpha Gang were told to summon her and Spiny, but Ace and Paris surrounded them.

In this season, she was used far less often than before, partly owing to the Alpha Gang's marked decrease in taking part in dinosaur battles by this point. She first appeared in her full size during the Ancient China Arc, the third arc of the season, but it wasn't in a battle. In her first battle, at almost halfway through the season during The Third Cosmos Stone, she used her DinoTector form to defeat Gabbro's Carcharodontosaurus, but this was the last dinosaur she would defeat. After that, she lost all of her battles (Genie, Ankylosaurus, Gigas, Armatus, and was losing to Ace), and, unlike every other main dinosaur, didn't directly take part in the defeat of any of the Space Pirates' altered dinosaurs. Though she didn't reuse any of the Moves she'd used last season, she gained four new Moves, but only one of them, her Ultimate Move, was ever used more than once (twice, to be precise) or actually defeated a dinosaur.

In the finale, she helped break through the Dark Pterosaur using Spike Arrows in the 6-part Fusion Move, but was quickly defeated by Maximus with Spectral Punisher after she jumped in to protect Terry from the attack. She appeared again in the Backlander's Mesozoic forest projection after all the Space Pirates' remaining dinosaurs were rescued, but as she had been summoned by Seth's copied Stones to take part in the battle, she was forever locked from being summoned pet-sized again, a condition begrudgingly accepted. She and the other dinosaurs were again taken back to the future, this time on the recovered Space Pirate Ship.

Character Design[]


Tank's Japanese name, "Saika" (サイカ), is an allusion to her species name, Saichania, the "ch" being pronounced like a "k" in the Japanese version's pronunciation. Her English name given in the 4Kids dub is a reference to the ankylosaur family in general, as they are commonly given the nickname of "living tanks" due to their bony armor.

It is somewhat odd for her to be standing next to a dinosaur named "Spiny" in a team lineup despite her being the one covered in the most spikes.


She doesn't seem to be particularly close to any of the Alpha Gang, though like the other dinos is shown to like Rod and Laura better than the Alpha Trio. In Season 1, she is more successful in fighting than Spiny, but there were also battles in which she was ineffective, such as in Fashion Victims, when she was easily overpowered by the angry Anchiceratops with no way to defend herself. She is typically summoned by Ed, Ursula, or Laura.

Tank was originally a docile dinosaur, but shortly after she came into the possession of the Alpha Gang, Dr. Z used the Alpha Controller to make her more violent. He did this so that Tank could better serve the purpose of the Alpha Gang, but there were also disadvantages. The clearest example was in A Miner Disaster when she entered an in-progress battle and casually injured Futaba before walking off, ignoring Ursula's complaints that he was an ally, an act that made him befriend Zoe for healing him and later turn against the Alpha Gang. Although she proved to be tactically smart in the same episode by surprising Zoe from behind to make her drop the Move Card, she often acted rashly in many of her fights, such as The Haunted Hunt when she openly ran at Gigas, even though he activated Spectral Lancer and was able to defeat her.

Although Tank has a better relationship with the D-Team's main dinosaurs in Season 2, it can still be assumed that they never really became friends. However, she developed a good friendship with Terry and Spiny, and in the case of Terry, it went so far that she threw herself in to protect him from Maximus' Spectral Punisher, thereby defeating herself.


  • Ed's arcade comments:
    • Taiwanese: 保護身體的刺和尾巴的槌頭讓人不敢靠近它呢。
  • DS Game Encyclopedia entry: It is covered in spikes to protect it from its enemies. Way too prickly to hug.
  • In the English dub, she was initially called a male in her first episode, but was called a female in all later appearances. The original Japanese version always called her a female. However, in the French dub, she is still considered a male after this first episode until the end of the anime.
  • After Terry, she is likely the second strongest dinosaur of the Alpha Gang, judging by how physically weak Spiny is often shown to be. As this is by Alpha Gang standards, though, that isn't saying much.
  • Tank is the only dinosaur of the Alpha Gang who defeated a dinosaur (Utahraptor in A Game Show Showdown) the first time she was summoned to battle. Terry and Chomp defeated each other in Prehistory in the Making (Terry went down first), and Spiny was defeated by Ace in Battle at the Pyramids. Tank and Spiny were both defeated by Terry when first activated as wild dinosaurs.
  • She is rendered helpless when she is flipped onto her back. When that happens, Zander and Ed are usually forced to flip her back over—not an easy task, as she weighs several tons (except in episode 44, where she flipped herself back up by using Tail Smash).
  • She and Spiny are the Alpha Gang dinosaurs who did not defeat all the main dinosaurs of the D-Team (in her case, she never defeated Ace, while Spiny never defeated Paris, though he set up an opening for Tank to defeat her), despite all of them being enemies.
  • All of the dinosaurs she defeated with Earth Moves are Fire Dinosaurs (Daspletosaurus, Black T. rex, and Carcharodontosaurus).
  • Tank is the only main dinosaur that does not defeat any of the Spectral Space Pirates' altered dinosaurs.
  • When she fights the D-Team, she is often defeated by Ace using Ninja Attack.
  • Tank is the only main dinosaur who doesn't reuse any of her Season 1 Moves in Season 2.
  • Despite having a decent record by Alpha Gang standards in Season 1, she wasn't really successful at fighting in Season 2 (nor did she even battle much), only defeating Carcharodontosaurus.
    • She is also the only main dinosaur to not defeat a new dinosaur species in season 2, as another Carcharodontosaurus had already appeared in season 1.
  • Tank is the only main dinosaur who did not defeat another main dinosaur multiple times (Spiny defeated Ace 2 times, Terry defeated Chomp 3 times, Paris defeated Spiny multiple times, Ace defeated Tank 2 times, and Chomp defeated Terry multiple times).
  • Tank is the only main dinosaur to not use their Element's first After-effect Super Move as their first Move Card (her first was Dino Swing, Earth Barrier debuting later and only being used once ever).
  • Tank is often seen curling into a ball to roll or bounce around when in chibi form.
  • Although she is not quite as strong as Terry, she did manage to defeat some dinosaurs that defeated Terry, such as Ampelosaurus and Carcharodontosaurus (though she only defeated a weakened Ampelosaurus in a surprise attack and fought a different Carcharodontosaurus), though at the same time she was also defeated by some dinosaurs that Terry then defeated, such as Fukuisaurus, Saurophaganax (though she was defeated by it later after it was strengthened), and Gigas (the last two also defeated Terry at one time or another).
  • Tank is highly skilled at digging tunnels very quickly (both horizontally and even vertically), and is capable of creating smooth, circular tunnels in spite of having spikes on her back and sides. She also doesn't seem to leave behind any stray debris from carving out the tunnels, implying she may be compressing it against the surrounding material, which could account for their stability.
  • Tank is the only main dinosaur to have been defeated by all three of Space Pirates' altered dinosaurs (Gigas defeated her with Spectral Lancer in The Haunted Hunt, Armatus used Spectral Stinger in Clash for the Cosmos Stones, and Maximus finished her with Spectral Punisher in Fate of the Cosmos).
  • Tank is the only main dinosaur that does not defeat a dinosaur of her own Element (she fought against both of the Ankylosaurus and against Armatus, and was defeated in all cases).
  • Tank's roar was used for the Umoonasaurus in the mobile game "Jurassic World: The Game".[1]
  • Tank is the only Earth Dinosaur in Season 1 whose card was not activated with a Move Card (all of her Move Cards were later recreated by Dr. Z).
  • Tank is the only dinosaur to be defeated by Fire Scorcher more than once (unless one counts Terry being drained of energy after using the Move himself).
  • Tank is the only dinosaur in the anime that has inflicted a visible injury on another prehistoric creature (leaving a red patch on Futaba's neck in A Miner Disaster, and possibly by accident).
  • Tank and Ace are the only main dinosaurs to directly attack the Space Pirates as chibis: Tank did so in The Haunted Hunt when she rolled into a ball and bounced on Gabbro and Foolscaps' heads after Gigas was defeated by Chomp, Ace, and Spiny.
