Victory
 * Kakuryu (Dinoforce, 1989)
 * ID number: D-324
 * Accessories: Triceratops shell, shell back, "Tricera Gun", "Dino Blaster" Dinoking gun, Dinoking head
 * A redeco of the Pretender Monster Slog, Kakuryu transforms into a squat pincher monster via a simple process similar to the transformation scheme of both Goryu and Doryu. The largest among the inner robots of the Dinoforce, he unfolds in a comparatively complex fashion to combine with them to form the shoulders and upper torso of Dinoking. His robot form fits inside his soft-plastic Pretender shell, an armored Triceratops (albeit one with three horns in a row, unlike the actual dinosaur), which mounts both his smaller "Tricera Gun"—which he wields in robot mode—and his larger "Dino Blaster", Dinoking's weapon. Dinoking's head stores on the rear of the larger weapon.
 * 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.
