Beryudora (Body Part)
Subtitle: Coalescence Dinosaur (合体恐竜, Gattai Kyōryū?)
After three children had discovered and stolen a pile of dinosaur bones from a laboratory, they buried them in a nearly field as their secret, unaware that the field was filled with Dark Matter. The Dark Matter had taken the dinosaur bones and combined them together, creating the monster King Dainas from them. Once the kids found the bones they took were missing and had transformed into King Dainas, they tried to take a photo of their success. However, the flash of the camera agitated King Dainas and the monster attacked the kids without mercy. HEART was quick on the scene to stop the monster, but their efforts were only minimal with the children's lives at stake. Genki quickly transformed into Ultraman Neos and proceeded to battle King Dainas in rather silly ways, including Horseback riding and Bullfighting, but King Dainas quickly ended the nonsensical battle and trampled all over Neos in hopes of ending the battle quickly. Neos however did not give up and after regaining the upper hand against the monster, Neos then used the Neos fireballs to reduce King Dainas back into a skeleton, which then crumbled to dust and blown away in the wind.
- Although not physically seen, King Dainas is one of the monster that makes up Beryudora's right arm in Mega Monster Battle: Ultra Galaxy Legend The Movie. King Dainas is also the only monster from the Ultraman Neos series to assist in making up Beryudora's body parts.
- King Dainas' roars can be heard on the desert planet that Ultraman Zero was training on.
- King Dainas' roars are modified stock cat sounds.
- King Dainas is the the first chimeric monster to be made from dinosaurs rather than monsters.
