Testudo Oceanus

Testudo Oceanus (テストゥード・オケアヌス): A sea turtle Unknown wearing silver armor and a turquoise scarf, Oceanus was responsible for indirectly revealing to Hikawa the nature of the Lords' victims. He made his move again at Yamato Park, with Shouichi sensing the Lord. Oceanus manages to beat Shouichi until he transforms into Agito before Mana's eyes, but his armored shell made him immune to Agito Ground Form's Rider Kick in the first fight before retracting. However, with helping Terrestris in fighting G3, Agito drags Oceanus off to a disclose area with the second Rider Kick causing the monster's armored body to crack before he explodes.
