The series title forms from the Dragon Balls flying through space, in a tribute to Dragon Ball (1986). The opening credits end with all the Z-Fighters lined up, in a tribute to Dragon Ball Z (1989).
The second closing credits show the main characters setting out for a picnic at the twilight dawn, where a lot of stars appear in the sky (and Goku remembers his DB/DBZ early years).
The first closing credits opens with a flashback of Goku's life, then changes to Goku at present watching the sunset on a beach with his family and friends.
