Dragon Ball GT featured FOUR different end credit sequences/songs, which is astonishing considering it was the shortest lived of the 3 Dragon Ball series.
There are 2 versions of the opening credits. The first one, played for the first half of the series, ends with Kid Goku, Pan, and Trunks standing together on an adventure to get the Dragon Balls. The second, played over the latter half of the series, ends with Super Saiyan 4 Goku standing alone. Other than these differences, the sequences are the same.
