Dragon Ball Z: Supersonic Warriors (ドラゴンボールZ 舞空闘劇,Doragon Bōru Zetto Bukū Tôgeki) is a fighting game based on the popular anime series Dragon Ball Z. It was developed by Banpresto and released for the Game Boy Advance on June 22, 2004. Its Story Mode ranges all of Dragon Ball Z from the start of the Saiyan Saga to the end of the Kid Buu Saga.
The game pits two characters of the Dragon Ball Z franchise against each other in large environments, where they mostly fight in the air. The player can use strong and weak variations of close combat attacks, and charge their ki to fire strong and weak energy blasts. Each character also has three unique "Certain Kill" abilities that deal heavy damage to the opponent. The Certain Kill ability varies depending on where the player is located - above, below or horizontal to the opponent
Each character has three "levels" which makes them stronger and occasionally changes their sprites and abilities. This is used in story mode to simulate the characters being stronger or weaker than their opponents.
Some characters have special abilities which can be activated by charging Ki to 100% and then press both L and R button at the same time. These special abilities represent power ups (like LV1 Goku's Kaio-ken)
The player can also fight as a team, during which two or three characters are stacked up with their own health bars and can be changed between by pressing the L button.
Krillin (Normal for all three, but one Certain Kill ability changes from summoning Gohan at LV1, to Tien Shinhan at LV2, to using the Spirit Bomb at LV3, also at LV3 Krillin can use the Kaio-ken special ability)
Vegeta (Normal for LV1, Super Saiyan for LV2, Majin Vegeta for LV3 (Automatically a Super Saiyan 2 at LV3))
Story Mode lets the player select a character and go through a unique story, each with eight battles. Each character has a "What If..." scenario which differs from the original Dragon Ball Z story, but there are also three scenarios that follow the Namek, Android and Buu Sagas. Certain "What If..." scenarios also have a "Special Edition" ninth battle (such as Piccolo being revived and sparring with Gohan).
Challenge Mode pits the player against teams of certain characters one at a time. As the player defeats each team, new teams are unlocked, and the harder the team, the more points the player gets. You can't go over the Level 4 limit with your characters.
The Option Mode lets the player change the game's difficulty, unlock new characters, or view rankings of various scores you have gotten in different modes in the game. Unlocking characters and story modes costs points, which are obtained by winning battles, completing story modes, etc.
It also includes a 'museum' where the player can view the game's illustrations as displayed after completing the respective stories in story mode and listen to the characters' quotes which are otherwise heard during battle. Note that this is only available after acquiring the required amount of points.
Super Saiyans' eye color is blue in the game, which is different from all other media where their eyes are green.
At LV3, Krillin can use two of King Kai's techniques in story mode: the Kaio-ken (as a Special Ability) and the Spirit Bomb. These techniques are taught to Krillin by Goku (who had died of heart virus and returned to Earth for one day to teach Krillin the Spirit Bomb & Kaio-Ken which would give Krillin a chance to defeat Cell) in Krillin What-If story. Krillin defeats Cell using the Spirit Bomb and later fights Majin Buu who he defeats with a Kamehameha (with assistance from Goku in Other World).
Frieza has a similar power to Kaio-ken (as a Special Ability) in all three levels, though it has purple aura instead of red.
Super Buu's alternate costume somewhat resembles that of Evil Buu, although the skin is more purple than dark grey.
Even though they are not playable characters, Trunks and Goten can be seen for a brief moment when Gotenks' Fusion Dance expires.
In the game Gotenks vest is green but in the anime it is blue.
