Tristan Liones

is the son of Meliodas and Elizabeth Liones, the prince of the Kingdom of Liones, a Holy Knight, and one of the Four Knights of the Apocalypse.

Appearance
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's.

At age 16, he is taller than both his parents and wearing a blue earring closely resembling Elizabeth’s on his right ear.

Upon his introduction in The Four Knights of Apocalypse, he wears a collared cyan button-up suit under similarly colored gloves, as well as silver boots and a chestplate baring a golden crest. Over all of this, he wears a baggy, yellow button-up jacket with thick white lining and an orange crest, worn with only the topmost button done. Before leaving Liones, Tristan receives a new outfit composed of a white shirt with turquoise edges on the sleeves and collar frills topped with a winged brooch, black pants and golden armor on the right leg and foot.

When using his Goddess Powers, he gains a triskelion in both eyes. He then can gain Goddess wings for flight.

When fully using his Demon Powers, his eyes turn jet-black, with branch-like lines coming from them, and a large black mark on his forehead in the shape of a 4-pointed star. While less used, he can then also gain demonic wings for flight.

It has also been shown that he can activate both his goddess powers and demon powers at the same time, resulting in his left eye being completely black and his right having a triskelion in it. While not always the case it has been shown that the left eye can begin to have dark lines coming from it.

Personality
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, including his father and other Sins upon hearing how they were framed years ago yet didn't know how they were framed until learning from Gowther's "story".

After learning about his parent's journey around Britannia and fighting the Ten Commandments, he desires to become the Seven Deadly Sins due to their heroics in saving the land from the Demon King and Cath Palug, showing that he has great respect and admiration for heroes.

During the current events of the Four Knights of Apocalypse, we see that 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.

When using his Demonic Power, he seems to become more violent and serious, abandoning his pacifistic ideals, becoming willing to attack an enemy.

We also see that he is reluctant to use the Demonic power that he has inherited from his father, for fear of being called a monster and being compared to his father.

Perhaps as a result of his demonic powers, he seems to prefer his mother over his father, as he happily takes any comment pointing out his and his mother's similarities with joy. As well as happily agreeing he and his father are not alike, despite people pointing out that he is more like his father after using his demonic powers, which he seems to dislike hearing.

Abilities/Equipment
At age 10, Tristan is shown to possess above average combat skills, both barehanded and with a sword. Gowther claims he possesses an impressive Power Level for a boy his age.

At age 16, his combat abilities seems to have improved greatly. He is also shown to have inherited Goddess powers from his mother and Demon powers from his father, and the ability to manifest them separately or simultaneously.

Abilities

 * An archetypal magic technique of the Goddess Clan that counteracts darkness by disintegrating it with light particles.


 * Flight: Tristan can manifest two pairs of Goddess wings to fly. He can also manifest two pairs of demonic wings to fly when using his demon powers.


 * This ability allows Tristan to reflect magic attacks aimed at him back at the enemy, but with much greater power; therefore, the stronger the opponent's powers are, the stronger the rebound becomes.


 * Demonic Mode: Tristan can enter this state to gain more power to fight enemies. However, Tristan states that the amount of time he can use it is limited, plus he doesn't like using it since he tends to lose control of his actions and it can be hard for him to switch back. In this state, Tristan is able to rip off body parts of Melagaland with ease, whereas before none of his attacks or the other Four Knights of the Apocalypse barely did anything. With Melagaland's technique Meifu no Bansan, he was able to scare away the hands from the underworld with just his demonic presence alone.Tristan also can make use of the power of darkness of the Demon Clan.

Weapons
Tristan uses a pair of blades, one black, one white. It is stated that he also owns several other swords. In his battle against Io he uses a new pair of swords being one angelic themed and the other demonic themed. His favorite pair being named "Mael" and "Estarossa".

Meliodas
Meliodas is Tristan's father. At first Tristan considered him a short, irresponsible and alcoholic person who touches Elizabeth's breasts every day, but after witnessing the real story of the Seven Deadly Sins from Gowther, he comes to respect him as a hero and desires to become one of the Seven Deadly Sins. As he gets older, he seems to harbor resistance to using his demonic powers and is happy when an enemy says he and his father are not alike. Tristan was shown to be somewhat jealous of the trust and respect Meliodas shows Lancelot, when fighting against King Arthur.

Elizabeth Liones
Tristan is shown to have a close and loving relationship with his mother as he trusts her by confiding in her when he believes his father and the other Sins to be evil traitors. He also seems to be overjoyed when Chaos Melascula compared him to her. Tristan is also shown to be curious about his mother's past and wanting to know about the origins of her nickname "Bloodstained Ellie". He also displays favoritism towards and comfortableness with his mother's powers.

Isolde
Tristan cares about her but is unaware of her implied feelings for him. Tristan thinks she's earnest and straightforward.

Percival
The two have shown to have a friendly bond with each other. When the two first met, Percival had lost control of himself after the Tristan Platoon was attacking his friends, deeply wounding them. When Tristan saw this, not knowing the full situation, they tusseled and, during their fight, he thought Percival might be a demon due to the language he was speaking, but he ruled it out after Percival was not affected by his Ark. After he was brought back to his senses by his friends and the situation got explained, Tristan and Percival started bonding, acknowledging each other's abilities and potential, learning more about each other, and fighting alongside each other. Following the fight in Liones, they have become comrades and protect each other.

Gawain
Tristan has been shown to be friendly towards her and knowledgeable of exactly what to say to cheer her up by reinforcing her belief that she is the strongest. The two have had their disagreements especially when it comes to dealing with an enemy and again when Gawain attacked Percival.
