Jay

Jay is one of the prankster twins on the Starship Tetra. The two share a common interest in pulling off pranks and generally causing mischief, especially upon Ai. They also tend to complete the other's sentence, or at least rephrase it in a different order. While they appear to be inseparable, they often blame each other when losing a battle. He is based on the J and L-shaped Tetrominoes.
