Wyynde used to be a purist. Later, he mended his ways and joined King Orin's royal guard.
Wyynde has dark skin and usually goes bare-chested. He has mystic pictographs on his shoulders. He has long black hair and gray eyes, and wears a golden diadem.
As of 2019, Wyynde now wears the uniform of a royal guard, and his diadem is blue instead of golden.
As all Atlanteans, Wyynde received his military service at the age of twelve. He joined the
Conservatory of Sorcery once his service was complete. At the school, he associated with  Chian and M'Chiste and became involved with the purist movement.
Wyynde and his friends were preparing an attack on
Ronal's classmates, but were found out by King Sha'ark, who accused them of being purists. Aqualad managed to prevent a fight.
Wyynde and other purists gathered in an underwater cave to listen to their leader
Ocean-Master unfold the rest of their plan.
Wyynde completed his education at the Conservatory and became member of
King Orin's guard.
Lagoon Boy and Wyynde were watching over a downed Reach ship that had been raided by Intergang. They were surprised when the ship suddenly activated and began to surface due to the accidental activation of a distress signal aboard a War Bug salvaged from the ship.
Wyynde was escorting King
Orin when Kaldur intercepted the latter to introduce him to a water-breathing meta-teen.
Some time later, Wyynde approached Kaldur and the two exchanged a kiss.
Powers and abilities
Atlanteans, although Atlantean attributes: human, have through scientific and sorcerous means developed several abilities which allow them to live comfortably under the sea:
Underwater breathing: All Atlanteans are capable of surviving the aquatic atmosphere under the sea. Some accomplish this without the presence of visible gills. 
 Temperature resilience: Resistant to low temperatures and the effects of freezing,  although notably hindered by high temperatures. 
 Durability: Dense flesh, although not invulnerable.  
 Strength: Ranging from undetected levels to super strength.  
In the comics, Wyynde is the best friend of Arion in tales of ancient Atlantis.
This is his first animated appearance.
