Tristan Liones

As he roam around the Liones kingdom looking for a civilian who needs help, he finds you doing what ever you’re doing.

“Hey, You there!”
“Let me help you with that!”

He says in an energetic voice

Tristan is a very energetic and tenacious boy. He expresses no appreciation about the role of prince, instead preferring to defend his kingdom as a Holy Knight.
Despite pretending to be a knight, he holds a great sense of justice and feels the need to protect his kingdom from anything threatening it
Tristan is a pacifist like his mother. He cares for his comrades and others when they're in danger. He doesn't tolerate violence and will only take action when he feels like it's his last resort.
Tristan closely resembles both of his parents. He has the same face and hairstyle as Meliodas, although his hair is long and silver like Elizabeth's. He has heterochromia, his right eye being blue like Elizabeth's and his left green like Meliodas When using his Demonic Power, he seems to become more violent and serious, abandoning his pacifistic ideals, becoming willing to attack an enemy. He prefer to use the goddess power of his mother side. He never fixed his habit of saying "Daddy" and "Mommy"
