Rairyu
- Rairyu is a Decepticon from the Victory portion of the Generation 1 continuity family.

Rairyu (ライリュウ Rairyū) is the idiot amongst a team of idiots. When he manages to form a coherent word it is cause for celebration. Oddly, he still doesn’t attract the criticism or ridicule of his teammate Kakuryu. Still, he is a vital member of the Dinoforce if only because his absence would leave Dinoking with an even weaker stomach than normal.

Notes
- Rairyū corresponds with 雷竜, meaning "Thunder Dinosaur". The term is a Japanese adaptation of "Brontosaurus", which means "thunder lizard" in Greek. The name Brontosaurus was synonymised with Apatosaurus until 2015 when Brontosaurus was revived as a distinct animal.
- The Dinoforce shells are notable for developing a green patina on the painted-gold portions, as well as a slimy texture over their whole surface over time. What causes this is unknown, but ick. Even previously-unopened samples will develop this nastiness. While some water and a little bit of hand-soap should take care of the slime, there's not much to be done about the green discoloration.
- Rairyu's depiction in fiction as the dumbest member of Dinoforce is at odds with their tech specs, which show his intelligence of 5 to be the highest of the team. The reason for this discrepancy is unknown.
- The Victory anime depicted the Dinoforce members as carrying melee weapons, rather than the blasters the toys actually came with.
