Ryusoul Gattai KishiRyuNeptune (竜装合体キシリュウネプチューン Ryūsō Gattai KishiRyūNepuchūn) is the mecha for Ryusoul Gold in Kishiryu Sentai Ryusoulger.


KishiRyuNeptune is Kishiryu MosaRex's's humanoid form which it changes into when Canalo takes command with his own spare RyuSoul. Like KishiRyuOh, KishiRyuNeptune is fast and agile, but skilled in underwater combat. KishiRyuNeptune possesses more power than KishiRyuOh Five Knights as the former overpowered Gachireus. It wields the KnighTrident (ナイトライデント Naitoraidento) tail blade, and can launch the AmmoKnuckles for a rocket punch attack. Its finisher is the KishiRyuNeptune Tornado Strike (キシリュウネプチューントルネードストライク KishiRyūNepuchūn Torunēdo Sutoraiku) where KishiRyuNeptune jumps in the air and dives back down with the KnighTrident spinning in a drill manner that pierces through the Minosaur.

Long ago, Mosa Rex, along with the other Kishiryu, fought along with the Ryusoul Tribe to keep the world safe and at peace. However, when the tribes discovered that Mosa Rex, Pterardon, and Tyramigo can combine with devastating results, Mosa Rex grew concern and fearful for what his power can do. With many members of the tribe wish to use the newly form Ryusoul Gattai King KishiRyuOh to control the world for peace, others refused and thought this was an evil action. A war soon break out, with Mosa Rex siding with his sympathizers. At the end of the war, he and his allies decided they wanted nothing to do with the other tribes and left for the sea. Mosa Rex would forever remember how power hungry the Land tribe have gotten, while still fearing the destruction nature of his power.


Kishiryu MosaRex

―Ryusoul Gold summoning MosaRex.[src]

Kishiryu MosaRex (騎士竜モサレックス Kishiryu MosaRekkusu) is Ryusoul Gold's partner in Kishiryu Sentai Ryusoulger. It is modeled after a Mosasaurus. In its default form, MosaRex is armed with the MosaRex Head (モサレックスヘッド Mosarekkusu Heddo), the KnighTrident tail blade, twin four-shot missile launchers (one on its left and right side underneath each fin), and its own massive jaws. Additionally, it is capable of flight. In its KishiRyuNeptune form, it forms the main body, legs, and its missile launchers form the arms while its RyuSoul forms the head.

Like Kishiryu Tyramigo and its sibling DimeVolcano, MosaRex can communicate with humans, as well as speak for itself with repetitions of "Mosa!". Much like DimeVoclano, it speaks with full sentences on a regular basis. Due to a tragic event in the past, MosaRex harbours a strong distaste for the surface dwellers and those from the Sea Ryusoul Tribe who interact with them.
