This article is about a/an mecha in Kishiryu Sentai Ryusoulger.

Kishiryu Pterardon (騎士竜プテラードン Kishiryū Puterādon) is an auxiliary Kishiryu in Kishiryu Sentai Ryusoulger. It is modeled after the Pteranodon.


A giant Kishiryu based on the Pteranodon, Pterardon grants the abilities of the HieHie Armor, which allows the user to use ice-based attacks and fly at superspeed. In combat, it has ice-based abilities, can fire a sub-zero ice beam from its beak, achieve space flight, fire energy beams from its arms, and wields the Pterardon Head (プテラードンヘッド Puterādon Heddo), the Knight Edge (ナイトエッジ Naito Eiji) wings and the HieHie Claw (ヒエヒエクロー Hiehie Kurō) on its short tail.

Appearances: Ryusoulger Episodes 31-32


After flying into space to avoid being sealed by Seto 65 million years ago, Pterardon managed to get itself trapped in its pit mode, robbing it of its true abilities and falling back down to Earth in the ocean. On MosaRex's order in the present, Oto brought Pterardon to the Ryusoulgers, which lead to reawakening the sky Kishiryu as Tyramigo attempted to eat Pterardon after mistakening it for an egg.


Pit Mode

Pit Mode, called Pi-Tan (ピーたん Pītan) by Oto, is Kishiryu Pterardon's sealed form that resembles an egg and a penguin. In this form, Pterardon loses access to its abilities and flight.

YokuRyuOh is the fastest Mecha the Ryusoulgers possess, capable of flight and can temporarily freeze the surrounding area for its own advantage. It wields the HieHie Claw on its right arm, which can be used for both offensive and defensive capability, and can attack with the YokuRyuOh Blizzard Storm (ヨクリュウオーブリザードストーム Yokuryuuō Burizādo Sutōmu), a freezing mist blast from the Pterardon Head. Its finisher is the YokuRyuOh Blizzard Claw Strike (ヨクリュウオーブリザードクローストライク Yokuryūō Burizādo Kurō Sutoraiku), where YokuRyuOh encases the HieHie Claw in solid ice and flies at superspeed before using it to pierce and destroy the Minosaur.
