Dragon Ball Z: The Legacy of Goku II is an action role playing game developed by Webfoot Technologies and published by Atari for the Game Boy Advance. It is based on the anime Dragon Ball Z and is the sequel to Dragon Ball Z: The Legacy of Goku. The game is followed by Dragon Ball Z: Buu's Fury.
The gameplay shows some similarities to the original Legacy of Goku game. Players still move around in a large 2D environment, interacting with objects and characters with the single push of a button. Players can select from a variety of attacks to use on enemies, which can either be melee or energy. However, there are also RPG-style stats which can be modified if players level up or if use different capsules which can be found throughout the game, also, unlike the previous game there are HP numbers appearing up the character when hit (red numbers show a loss of a HP and green numbers show a recovery of it).
After players have completed several events in the storyline, some characters have the ability to transform. By transforming, stats and speed receive a quick boost. Goku, Gohan, Vegeta, and Trunks undergo a Super Saiyan transformation when prompted and Piccolo simply takes off his weighted clothing (a large speed boost rather than a power-up, though he also slowly regains health while "transformed".) Unlike in the previous game, players now have the ability to perform various "side quests" and therefore can complete various tasks and fight some beings from the non-manga world of Dragon Ball Z (such as Frieza's brother, Cooler).
The game starts in the timeline of Future Trunks, drawing elements from the TV special Dragon Ball Z: The History of Trunks. Afterwards, it begins in the present and allows the player to assume the role of young Gohan. Further into the storyline, more playable characters appear (first Piccolo, then Vegeta, Future Trunks, and finally Goku), as well as more abilities up until the final battle with Cell. The game uses environments, enemies, attacks, and music directly from the anime itself.
