- "The rumbling thunder, Pteragordon!"
- ―ED theme lyric[src]
One of the Ten Great Zyudenryu, Pteragordon was a Pteranodon that agreed to be modified to fight the Deboss Army in ancient times, but was damaged in battle after his partner was "killed" and had to be sealed away on Gabutyra's Island to heal.
Once inserted with his Zyudenchi, Pteragordon can summon rumbling clouds filed with lighning bolts and capable of using them to attack his enemy in all directions. These lightning bolts were colored purple during his corruption and later yellow after being purified. Pteragordon also has a visor on his head as well as the Pteraiden-Oh head. They were briefly turned down during his corruption, and he used them again to protect himself from Deathryuger's Dark Melody that corrupted Tobaspino, Ankydon and Bunpachy. If Utsusemimaru were to lose his Gabrichanger, Pteragordon is capable of building and supplying its replacement.
Pteragordon was among the 24 dinosaurs to be altered as a Zyudenryu by Wise God Torin. He was among the last 11 Zyudenryu that still stood to protect Earth after all 13 Guardians were slain by Dark Species Deboth, forcing Zyudenryu Bragigas to use the surviving Zyudenryu's Zyudenchi to activate his forbidden attack and seal Deboth in his heart.
In the Sengoku Era, Pteragordon was partnered with Utsusemimaru while trying to protect it against Deboth Army lead by Chaos and Dogold. However, he was greatly injured and sealed inside Gabutyra's island while Utsusemimaru was possessed by Dogold in a plan to control him centuries later.
In present day, Hundred-Faced High Priest Chaos created a evil-laced copy of Pteragordon's Zyudenchi, allowing him to undo Pteragordon's seal to complete his plot of controlling the Zyudenryu to destroy the Kyoryugers and humanity by handing its control over to Raging Knight Dogold. However, Pteragordon was freed from the forces from the Deboss Army when his sealed-away partner was infused with Brave energy from Torin, Daigo, and Ramirez and broke free of Dogold's control, allowing the Zyudenryu to destroy the fake Zyudenchi the Deboss Army had created, then rearmed his partner with the Gabrichanger and his true Zyudenchi.
Kaminari Henkei Pteraiden-Oh
- "Pteraiden-Oh! (Shamisen music)"
- ―Transformation announcement[src]
Kaminari Henkei Pteraiden-Oh (雷変形プテライデンオー Kaminari Henkei Puteraidenō?, Lightning Transformation Pteraiden King) is the Zyuden Giant state of Pteragordon, known as "Pteragordon's strongest form".
Pteraiden-Oh is very sleek compared to Kyoryuzin, and because of this, it is a good deal faster, and can deal out a lot of damage in a hurry with its Ptera Cutter (プテラカッター Putera Kattā?) arm blades. However, because of Pteraiden-Oh's lithe frame, it cannot take a lot of damage. Also, it is somewhat weaker than Kyoryuzin.
One of its finishers is the Pteraiden-Oh Brave Finish (テライデンオーブレイブフィニッシュ Puteraiden'ō Bureibu Finisshu?), where the Zyuden Giant fires a stream of lightning bolts from the Ptera Head (プテラヘッド Putera Heddo?) cannon. However, it is noticeably weaker then Kyoryuzin's own Brave Finishes, and as such, Pteraiden-Oh has to land another attack to fully destroy a enlarged monster.
When Pteraiden-Oh was under the Deboth Army's control, its visors were pulled down, and it wore a giant black cape. The black cape is also bulletproof, able to resist multiple shots from Zyudenryu Parasagun.
Raiden Kamitsuki Gattai Raiden Kyoryuzin
- "Raiden Kyoryuzin! (Mixture of shamisen and samba music in harmony)"
- ―Fusion announcement[src]
Raiden Kamitsuki Gattai Raiden Kyoryuzin (雷電噛み付き合体ライデンキョウリュウジン Raiden Kamitsuki Gattai Raiden Kyōryūjin?, Thunder Biting Combination Thunder Dinosaur God) is the combination between Pteraiden-Oh and Kyoryuzin.
The majority of Pteraiden-Oh is formed into Pteragordon and placed on Kyoryuzin's back, except the head, where it replaces Kyoryuzin's standard helmet.
Armed with the power of flight from the Ptera Wings (プテラウイング Putera Uingu?) and the Goren Zyudenken, Raiden Kyoryuzin is peerless in the sky, now able to fight in the air without having to sacrifice strength in order to do so.
This combination's finisher is the Zyudenken Inazuma Brave Finish (獣電剣稲妻ブレイブフィニッシュ Jūdenken Inazuma Bureibu Finisshu?, lit. "Electro-Beast Sword Lightning Brave Finish"), where Raiden Kyoryuzin flies high into the air while the Kyoryugers channel electrical Brave to the Zyudenken. Once done, Raiden Kyoryuzin brings the electrified Zyudenken down with a mighty chop, slicing through the target.
Though Kyoryuzin is always in its default combo whenever it combines with Pteragordon to become Raiden Kyoryuzin, there is no reason why Pteragordon shouldn't be able to combine with Kyoryzin in all its other combos (e.g. Western, Macho, Kung-Fu). However, it might be because of who Pteragordon's partner is.
Its finishing attack is the Pteraiden-Oh Western Brave Finish (プテライデンオーウエスタンブレイブフィニッシュ Puteraidenō Uesutan Bureibu Finisshu?), where it uses the energy of the three Zyudenryu to create an orb which is shot from the Parasa Beam Gun.
Pteraiden-Oh Ankydon (プテライデンオーアンキドン Puteraidenō Ankidon?) is the Biting Combination of Pteragordon and Ankydon. This combination was used as a one-two attack plan against an enhanced Cambrima, who was on even strength with Kyoryuzin Macho due to their similar weapons, with Pteraiden-Oh's part of the plan was to use the Ankydon Hammer to smash the Cambrima's kanabo, though the Zyuden Giant had to spin into the air for momentum for the proper amount of force.
Pteraiden-Oh Bunpachy (プテライデンオーブンパッキー Puteraidenō Bunpakkī?) is the Biting Combination of Pteragordon and Bunpachy.
Its finishing attack is the Pteraiden-Oh Bunpachy Brave Finish (プテライデンオーブンパッキーブレイブフィニッシュ Puteraidenō Bunpakkī Bureibu Finisshu?), where it shoots a blast of lightning from the Ptera Head cannon before hitting the opponent in the face with the Bunpachy Ball.
Pteraiden-Oh Parasagun (プテライデンオーパラサガン Puteraidenō Parasagan?) is the Biting Combination of Pteragordon and Parasagun.
Its finishing attack is the Pteraiden-Oh Parasagun Brave Finish (プテライデンオーパラサガンブレイブフィニッシュ Puteraiden'ō Parasagan Bureibu Finisshu?), where Pteraiden-Oh makes a sphere of lightning that attaches to the barrel of the Parasa Beam Gun, then is shot forward with great power.
Pteraiden-Oh Dricera (プテライデンオードリケラ Puteraiden'ō Dorikera?) is the Biting Combination of Pteragordon and Dricera.
Its finishing attack is the Pteraiden-Oh Dricera Brave Finish (プテライデンオードリケラブレイブフィニッシュ Puteraidenō Dorikera Bureibu Finisshu?), where it uses the Dricera Drill to pierce through the opponent while flying at the enemies at high speeds.
Tategami Raiden Kyoryuzin
The head of Tategami Lioh combines with Raiden Kyoryuzin to form Tategami Raiden Kyoryuzin. With the help of Daizyuzin and AbarenOh, they attack with the finishing move, Zyudengeki Densetsu Brave Finish.
- Pteragordon Zyudenchi (プテラゴードン獣電池 Puteragōdon Jūdenchi?): 6 golden Zyudenchi holding the Kyoryu Spirit of the Pteranodon; the Deboth Army made a functioning evil fake to control Pteragordon, but the real ones were reused by Kyoryu Gold upon the Kyoryuger's freedom.
- Pteragordon Spirit Ranger Gold ver. (プテラゴードン スピリットレンジャーゴールドver. Puteragodon Supiritto Renjā Gōrudo Bājon?) - A clear version of the Pteragordon Zyudenchi that when used in the Gabrichanger allows Kyoryu Gold to enter Armed Mode and gain access to a stronger version of his Zandar Thunder called the Golder Zandar Thunder.
- Pteraiden-Oh: to be added
Behind the scenes
All of the Zyudenryu/Zyudenchi sport a name that is a portmanteau between their effect/motif and their respective animal name, Pteragordon is a portmanteau of Pteranodon and Gorogoro (the Japanese onomatopoeiac word for "rumble"; often used in the context of thunder).
Pteragordon's Zyuden Giant name contains the word "Raiden" (雷電?), which means "Thunder and Lightning". This ties in with the electric naming schemes most of the Kyoryuger's gear follow.
- Pteragordon is the first Zyudenryu that is capable of assuming a robot form all on its own.
- Pteragordon is similar to GaoHunter from Hyakujuu Sentai Gaoranger in that both first appeared in an "evil" form.
- Pteragordon is the first Pteranodon-themed Mecha that is capable of assuming a robot form all on its own and to be colored gold and whose pilot is a sixth ranger.
- In the South Korean Kyoryuger dub, "Power Rangers Dino Force", Pteraiden-Oh is renamed "Ptera King". Like the other Zyudenryu, Pteragordon himself is not renamed. 
- Pteragordon is the first Zyudenryu that isn't a dinosaur (Pteranodon).
- In Power Rangers Dino Charge and Super Dino Charge, Ptera Zord (American counterpart) is a Pterodactyl, not a Pteranodon. However, they still use the scene Zyudenchi comes to Pteragordon to show the Dino Charger come to Ptera Zord, only improve the graphic. This is somewhat true, because Pterodactyl and Pteranodon are both genuses of Pterosaur.
