There is a variant of the pirate robot built by the Red Ribbon Army. Its description states:


The original was built by pirates. Also, the name Geromantium refers to a character from the series named Dr. Gero.

One area in Legacy of Goku II has six Super Nintendo game boxes on display. Though incredibly low resolution, these appear to be:
• Final Fantasy IV (released in the U.S. as "Final Fantasy II")
• The Legend of Zelda: A Link to The Past
• Pilotwings
• Paladin's Quest (or possibly E.V.O.: Search for Eden)
• Secret of Mana
• Super Metroid

There is also a Game Boy Advance sitting on an adjacent table.

Though none of the Dragon Ball Z: Legacy of Goku games were released in Japan, a special version of the second instalment called Dragon Ball Z: The Legacy of Goku II: International was released exclusively in Japan. This edition was published by Banpresto and featured updated character portraits and the character's names changed to their original Japanese names, though Mr. Satan is still referred to his English name "Hercule" on a parade float.

The opening FMV is present in the US and Japan (international) versions but was removed in the European version due to the need for storage space to add other languages.

If the game detects that it is being run illicitly, when Gohan first goes to the world map, a message will appear saying "This game will not run on the hardware found.". You will then be sent to the title screen.

The games working title was Legacy of Goku 2: Future Shock. The title was dropped mid-way through development. All three LoG games were meant to have subtitles.

An NPC appearing in Dragon Ball Z: The Legacy of Goku II is potentially a reference to American domestic terrorist Ted Kaczynski, the Unabomber. It should be noted that while his character portrait and overworld sprite look similar to Kaczynski, it is used for several different NPC characters in the game, so it's unknown if he was originally intended to physically resemble the real-life Unabomber. However, like the Unabomber this character is also named Ted, he moved to a cabin in the woods, and believes society is too reliant on industrial technology, even complimenting Vegeta on "blowing up" a neighbor's generator after he failed to destroy it himself. His dialogue is the following:

In Capsule Corp, a yellow hovercar can be found to the left directly after entering the building. A scientist working on the hovercar reveals that it's a prototype model that he predicts will be a "huge hit" when it's finished and released. According to the game's official strategy guide, this hovercar is the same one used by Goku and his driving instructor in the "Dragon Ball Z" filler episode "Goku's Ordeal", where Goku and Piccolo are forced by Chi-Chi to take driving lessons.
