Skyhawks characters

Jay

Jay was Ace's twin brother and Kai's younger brother. He appeared to have a similar appearance to Ace but his eyes were dark blue and his hair was black and shorter than his brother's.

Jay was born to Sparrow Strike and Ida. He grew up on Terra Atmosia with his mother, father,  brothers Lightning Strike, Rocky, Kai and Ace, and sisters Addie and Parotia. He shows to be a good, kind, and caring boy as shown comforting Ace when their older brother is killed in a flood. As a teenager, he and Ace both shared a strong bond with each other. However, both were teased by Lightning and his buddies. Once, Jay accepts a dual with Strike. Strike accidentally shoots Jay in the chest, causing the latter to have a heart attack and fall from the fight. Ace comforts him but Jay dies in his brother's arms as a result of the shock. Afterwards, Strike took no responsibility for Jay's death. Thinking Lightning Strike had purposefully killed his brother, Ace was drowned in a thirst for vengeance and anger. In the vision, Mirage shows Kaida her father's childhood and the scene where Jay dies is shown, scaring Kaida. In "Cave of Dangers", Ace reveals what happened to Jay to Aasira who was horrified and disgusted at what her grandfather had done.
