Kishiryu DimeVolcano

Main article: Kishiryu DimeVolcano

A giant Kishiryu based on a Dimetrodon, DimeVolcano grants the abilities of the MeraMera Armor, which allows the user to use flame-based attacks. In combat, it wields the Knight Fan (ナイトファン Naito Fan) flame-style sail on its back, the Knight MeraMera Sword (ナイトメラメラソード Naito MeraMera Sōdo) flame-style tail blade, and can breathe fire from its mouth. It provides the back, legs, and connection point for the arms of SpinoThunder. The back, tail, and legs form the chest armor, visor, and shoulder cannons of Gigant KishiRyuOh.

Kishiryu MosaRex

Main article: Kishiryu MosaRex

Kishiryu MosaRex (騎士竜モサレックス Kishiryu MosaRekkusu) is Ryusoul Gold's partner in Kishiryu Sentai Ryusoulger.[1][2] It is based on a Mosasaurus. In its default form, MosaRex is armed with the KnighTrident (ナイトライデント Naitoraidento) tail blade, twin four-shot missile launchers (one on its left and right side underneath each fin), and its own massive jaws. It forms the head, arms, body, and tail, while also serving as the connection point for the legs of SpinoThunder. Combining into SpinoThunder also causes the bridge of MosaRex's nose to raise and form a crest.

The AmmoKnuckles (アッモナックルズ AmmoNakkuruzu) are a pair of auxiliary Kishiryu. They are modeled after Ammonites. They form part of the feet of SpinoThunder.

KSR-BiriBiriSoul (Knight Mode)

BiriBiriSoul (Knight Mode)

The BiriBiriSoul (ビリビリソウル BiribiriSōru, lit. Shocking Soul) is the personal RyuSoul for SpinoThunder. It enables Ryusoul Gold to access the BiriBiri Armor. 


  • SpinoThunder's name is a mix of Spinosaurus and "Thunder".
  • SpinoThunder is similar to Samurai Gattai DaiTenku, as they're both mechas in the form of a different animal rather than the usual humanoid form. 
  • It may be the first (& so far only) Kishiryu to be made up of other Kishiryu.
    • The other known non-robo combination are made of KishiKyoRyu.
  • The combination with KishiRyuOh parallels(albeit slightly inverted) the combination of Cho Cho ToQ-DaiOh, with an orange mecha forming a visor on the face, along with a chest piece, while the rest of the combination provides additional height on the feet.
