Lucas Thalassa  

, タラッサ・ルーカス

King Thalassa Lucas (タラッサ・ルーカス, Tarassa Ruukasu), also known as Thalassa, was briefly mentioned in chapter 142 during Chopper's flashback. He is the ruler of Ilusia and appeared as a bearded, smoking man who showed a photo of Dragon to the Council of Kings six years ago. He warned that Dragons thoughts were dangerous and predicted that within six more years, they would become a significant threat to the World Governments. Despite only being seen in a flashback from six years ago, it is unknown if Thalassa is still alive or continues to reign as King of Ilusia. The name "Thalassa" comes from the Greek sea goddess who personified the Mediterranean Sea.
