Daguva fought the original in his Imperfect Form Kuuga, and was defeated. He was sealed by Kuuga in his sarcophagus along with him.
He is reawakened In modern times, he is unsealed by a team of archaeologists. Upon his release, he kills the archaeologists and revives the other Gurongi to restart the Gegeru, killing off 152 of the Gurongi he views as inferior. He also at some point gained a human form.
He later fights Kuuga in his Amazing Mighty Form and defeats him. However, he lets Kuuga live and allows him to get stronger to pay him back for not interfering with his trip around the country.
Daguva later initiates a systematic genocide of the human population in Japan. He later tells Yusuke to meet him at Mount Kuro for a final confrontation. Yusuke meets him in his Ultimate Form and Daguva assumes his Gurongi to fight Kuuga.
The two battle each other to the point that they're too weak to maintain their fighting forms. Despite this, they continue to fight each other as humans. Daguva eventually succumbs to his wombs and dies. His last action is to laugh and hope Yusuke becomes violent like he is.
