Using the scenes from the first sixteen episodes of Dragon Ball GT (known more commonly as the "Black Star Dragon Balls" Saga), Lost Episodes continue the gameplay changes added in Shadow Dragons. Lost Episodes also introduced a new method of winning the game; attaching three Wanted Poster cards to their corresponding Personalities (Goku, Pan, and Trunks), and playing the card "Captured!", allowed the player to win. Score planned a fifth GT expansion after Lost Episodes (as seen by the preview cards inserted into the Lost Episodes Boosters), called "Anthology", which would encompass the Dragon Ball GT series in its entirety. However, this set was never released and Lost Episode stocks were seemingly cut short. This made them hard to get with Ultra Rares such as Lv5 Pan, Lv5 Trunks and Bulma Sensei becoming considerably rarer than Z cards such as Goku, Super Saiyan 3 and Majin Vegeta, the Malevolent. Some Lost Episodes packs also had bonus "Skannerz" cards.
Personality cards in this set included Goku, Pan, Trunks, Giru, Dr. Myuu, Dolltaki, Bon Para Para, Son Para Para, Don Para Para, Emperor Pilaf, Mai, General Rilldo, Luud, Ledgic, Cardinal Mutchy Mutchy, Mutchy, and Zoonama. Sensei cards in this set included Bulma and King Kai.
