The Dragon Ball Z: Collectible CD Picture Cards were a series of multimedia pocket CD-ROMs released exclusively in Australia in 2001 and were compatible with PC and Macintosh. Designed and produced by Streamedia Pty Ltd, there were 10 CDs to collect, each featuring a different character and were available randomly in packets and as a promotion given away with the purchase of Coca-Cola products. Each disc contained information on the respective character and each Dragon Ball Z saga up to the Cell Saga, information on merchandise and a "BattlePrint" activity mode. Despite saying "DBZ Set 1" on the packaging, no additional series were ever released.
Mr. Satan/Hercule is usually depicted in Dragon Ball video games as wearing a jetpack during gameplay despite not actually doing so in the anime or manga. This was done for player convenience so that he would be able to fight the other flight-capable characters.
In March 9, 2011, Toei Animation publicly recognized that the music composer Kenji Yamamoto had committed plagiarism in many of his works. As a result, each of his music tracks featured in any Dragon Ball game was replaced in every re-realease starting with Dragon Ball Z Budokai HD Collection.
One of Jeice's pre-battle voice clips in the first Budokai Tenkaichi is "Don't play stupid with me, wanker!" In both Budokai Tenkaichi 2 and 3, the word "wanker" was removed, but instead of re-recording the line, they edited the existing one. The "w" can clearly be heard spoken after he says "Don't play stupid with me!"
In the Budokai games, even if Cell has reached his Semi-Perfect, Perfect, and Super Perfect forms, whenever he receives a powerful hit and screams in pain, he sounds just like Imperfect Cell. This mistake continued on into the Budokai Tenkaichi series as well, as take-damage voice cuts were never recorded for those forms.
Many Dragon Ball Z games give Broly a form called "Legendary Super Saiyan 3", a form which never appeared in the show.
