Directory
''A mild-mannered elder of Apotos whose honesty and integrity have earned him the villagers' trust. He does tend to be something of a worrywart, though. Lately, concern for the planet and the villagers has kept him up at night, leaving him a bit bleary-eyed.''

PS3/Xbox360
According to Gregorios, he has lived his whole life in Apotos. Following the shattering of the Earth in the beginning of Sonic Unleashed, Gregorios' worries for the townspeople's safety and the planet's following fate, let to him to developing a slight degree of insomnia. When Sonic and Chip arrives at Apotos, Gregorios was pleasantly surprised to see these new travelers, and gives some advice for Sonic and Chip when navigating in Apotos, and provides directions to the local Entrance Stage. He is then asked by Sonic if he had seen Chip from somewhere before, as Chip had amnesia, but Gregorios told them that he had no recollection of him ever seeing Chip.

During nightfall however, Gregorios was possessed by Dark Gaia's minions. Their influence resulted in Gregorios losing interest in everything around him, including his own worries and did not what would happen, as the planet now had shattered.

Gregorios continued to have this behavior for some time, shifting between his moods between day and night. He was however aware that strange feelings overwhelm him at night and worries if it could be monster, dark spirits, ghosts, robbers or even stalkers. He was however finally freed from their influence when Sonic and Chip returned and exorcised him. As Gregorios recovered, he could sense the dark presence was gone, but claims he cannot relax yet as he believes they could still lurk in the area. He is however too afraid to look for them himself. Afterwards he says to Sonic and Chip that it was undeniably the presence of dark spirits he felt earlier, and that the very thought of them attacking again leaves him so worried that he thinks that he may never be able to sleep again.

Following his exorcism, Gregorios would spend his daytime exorcising nearby dark sprits. He would however apologize for startling Sonic when he tried to exorcise him.

During nightfall, Gregorios gets scared when finally gets a good look on Sonic the Werehog. He calms down however when sees that he is the one who helped him, but admit that his appearance is frightening. Sonic however tells him that his is Sonic the Hedgehog, but Gregorios is confused and finds it hard to believe. He therefore decided to test Sonic. Having heard that Sonic is faster than sound, Gregorios requests Sonic (in his werehog form) to retrieving his glasses from outside town in the blink of an eye. After Sonic returns with his glasses, Gregorios admits Sonic was fast and that he should believe Sonic, but he still cannot accept that he is is the real Sonic.

During the following night, Sonic returns, and Gregorios begins to find Sonic the Werehog's appearance even more frightening. Claiming that he cannot accept that he is the real Sonic, Gregorios decide to test Sonic again. This time Gregorios wanted to see if Sonic had Sonic's legendary courage, by seeing if he could fend off his from attackers and protect him. After seeing Sonic succeed once more, Gregorios starts to think that he might be the real Sonic, but cannot see beyond Sonic the Werehog's scary appearance and has second thoughts.

During the third night, Gregorios still find Sonic the Werehog scary and claims that he still cannot accept he is Sonic just because he is fast and brave. Having heard that Sonic is a kind soul who frees the oppressed, Gregorios tests Sonic once more by seeing if he could find his lost, valuable book as a test of kindness. As Sonic passes Gregorios' test again, Gregorios admits it was a kind act and admits he is finally beginning to believe that he is the real Sonic. He then hears how sonic revert between forms, but wonders how this is possible and starts to doubt again.

As the forth night arrived, Gregorios says he cannot get over Sonic the Werehog's scary appearance, even though he has passed all his tests. Therefore, as a final test, Gregorios enlists Sonic to find the town's true treasure, as only Sonic would be able to do it. Sonic however succeeds in finding the treasure, the Maiden Statue, and hands it over to Gregorios. Having seen Sonic the Werehog clear all his tests, Gregorios announces with great joy that he is finally convinced that he is the one, true Sonic.

Following his conviction, Gregorios asks Sonic to save the planet and says that he will remain in Apotos, praying for his success. Gregorios would then during daytime provided Sonic with hints to where he would have to go next on his journey, by "receiving messages from above".

PS2/Wii
When Sonic and Chip arrives at Apotos, Gregorios greets the traveling duo and asks what brings them here. He is then asked Sonic if he knows Chip, as Chip had amnesia, but Gregorios says that he cannot recall this gentleman. He proceeds to says that his head is filled with thoughts about the local Sacred Shrine, and that he worries that since the tremors from the planet's shattering had made the town's tourist visits decline, their town may face ruin. However, since Sonic and Chip had come all this way, Gregorios leads them to the Sacred Shrine.

During the following night, Gregorios meets up with Sonic and Chip again, but he cannot recognize Sonic as a Werehog and asks if they have met before. He does not believe however that Sonic is the same blue hedgehog he lead to the shrine and mentions that he had heard Eric lead a yellow fox to the shrine. He also mentions that the streets of their town had become dangerous with signs of ghosts, and tells Sonic to be careful.

From then on, whenever Gregorios talked to Sonic at night, he does not believe he is the blue hedgehog he met this afternoon and told him to stay away whenever Sonic looked at him.
