02 / The toy

The warrior that disappeared
Daijinryu nearly had a very different face. Drawing 27 gives the creature a separate humanoid head, square shoulders and a blocky armored body. The finished design keeps the dragon’s long neck and open mouth even when it stands upright.
The artbook explains the change in direction: Daijinryu began as a strengthened version of Ryuseioh, then a change to the setting made it a giant life form instead. The warrior sketch preserves a possibility that the finished dragon left behind. Compare it with Ryuseioh, whose dragon and warrior identities both survived. Artbook, p. 086.
Look especially at the head in drawing 27. A small separate face changes the whole character of the body beneath it. Early sketches, p. 150.
Look closer

Drawing 27: a proposed warrior transformation. Compare the separate face with the long-necked finished dragon beside it.

The finished upright dragon retains its antlers, open mouth and long neck.

A dragon in two directions
The finished Daijinryu still transforms, but it stays a dragon. Rising Dragon Mode stretches the body horizontally over four clawed feet. Dragon God Mode raises the long neck and pale segmented underside above the legs. The antlers and mouth remain its face in both forms.
In Gosei Sentai Dairanger, this is a cosmic life form rather than another team warrior. The artbook places its arrival in episode 37. That story identity makes the rejected humanoid especially revealing: the final silhouette belongs to something outside the familiar row of armored heroes. Artbook, p. 086.
The original DX photographs show the same contrast in a physical object. Follow the long tail and silver throat from the low, four-footed figure to the standing toy in the opening pair. These photographs document the two configurations; the unrealized warrior sketch is not a third toy mode. Original DX photographs.
Look closer

Rising Dragon Mode, with head studies and the upright form's rear view. The long body and tail make a different silhouette while preserving the same colors and mechanical details.

The head makes the difference
Return to drawing 27, then look at the finished head. The proposal puts a warrior’s face between two shoulders. Daijinryu instead raises a dragon’s mouth on a long neck. Standing up did not have to mean becoming human-shaped—and that is the choice that gives this giant its presence.
