A member of the Inhuman Royal Family, Triton is cousin to King Black Bolt and Queen Medusa, and brother to Karnak. His origins lie within the hidden city of Attilan, where infant exposure to Terrigen Mist triggered aquatic adaptations: green skin, gills, and an enhanced physiology for underwater survival. These mutations grant him the ability to breathe underwater and endure extreme oceanic pressures, while also enabling him to function on land and within lunar environments without supplemental breathing apparatus. Following the Royal Family's relocation to a floating city above the moon, Triton engages in training and diplomatic duties. He exhibits advanced combat skills during sparring sessions with allies like the shapeshifting human Chloe and Kamala Khan (Ms. Marvel), demonstrating proficiency in martial arts and tactical acrobatics. His fighting style incorporates flips and evasive maneuvers, though psychological tactics, such as an opponent mimicking Black Bolt's appearance, can momentarily disrupt him. Amid escalating tensions between Attilan and Earth, Triton supports the Inhuman royals' diplomatic efforts with humanity. He stands alongside Black Bolt and Medusa during critical meetings with the Avengers, meetings sabotaged by Maximus, Black Bolt's brother, who frames Earth's heroes for an attack. This deception leads the Inhumans to declare war on Earth. Triton remains loyal to the throne throughout Maximus' manipulations, emphasizing his integration into Attilan's hierarchy and commitment to its sovereignty, though he is not depicted directly involved in ensuing combat preparations.
