Alternate endings
After you complete the story mode you will be able to go back and do new missions in the three different sagas to unlock characters and items. After you do the new missions for each saga (can be done randomly), another mission opens where the story from the cartoon and game is changed. In the Saiyan Saga, you play as Vegeta and take on the Z Fighters. After Vegeta defeats each of them he turns Super Saiyan. In the Namek Saga, you play as Frieza and once again take on the Z Fighters. Once they are defeated Freeza, will use the Dragonballs and ask to be invincible. His wish is granted and he destroys Namek and then goes after Earth. In the Android Saga, you play as Cell. After absorbing Android 17, Cell goes after Android 18. He will try to absorb her but Krillin will jump in the way and be absorbed instead. Cell will become a hilarious fusion between the two. He will then take on Yamcha. After the fight, Tien goes to blast him but Cell suddenly wakes up from a dream. He is in his Perfect form waiting for the Cell Games.

These episodes can be unlocked when you complete Story Mode at any level.

Go into those episodes to get new players and new player abilities, such as a Super Saiyan for Vegeta.

Tournament wins
When in Tournaments, instead of trying to kill the CPU opponents, just lure them close to the edge of the ring. Tap X + Down to move behind the opponent, then use a strong move to knock them out the ring.

Taunts
Taunting (press Punch + Kick + Guard + Escape) will lower your opponent's Ki gauge by 1.

The Dragon Balls
Within the game you can collect the seven Dragon Balls. In order to get them, you have to buy them at Mr. Popo's shop. However, they are very rare. They cost 8000 Zenie each and will only appear in a "Recommended" or "Gambled" Capsule. After collecting all seven, go to the Caps List option in the "Edit Skills" menu. Then go along to the second to last list. If all seven Dragon Balls are present, press X and you will be asked if you wish to summon Shenron. Select "Yes" and you will be given the option to "Breakthrough" three random characters. Breakthrough is a Capsule which will open all the Death Moves, Transformations, and Physical Moves of the character in possession. However, it takes up seven ability slots and cannot be equipped in conjunction with anything else. After choosing your character, the Dragon Balls will disappear and you will have to collect them all again.

If you do not like the random choice of three characters that Shenron powers-up, restart the PlayStation2. All your Dragon Balls will still be there when the game is resumed. Summon Shenron again until you like the choice of the three random characters.

Get Dragon Balls quicker
Go to the Skill Shop and go down to the "Recommended" section. It will tell you what item it is. If it is not a Dragon Ball, exit and re-enter the shop again. The Recommended item will have changed. Keep repeating this until you see a Dragon Ball in the Recommended section. Make sure you have enough money, as each Dragon Ball costs 8,000 Zenie.

Keep and reuse the seven Dragon Balls
This trick requires three memory cards.

1. Save the original game on the memory card A, then save it again on memory card B or copy it from the PlayStation2 browser.

2. Create a new game and save it on memory card C.

3. Go to "Trade Skills" under "Edit Skills" with memory cards B and C and in the PlayStation2. Trade the Dragon Balls from memory card B to memory card C.

4. Remove memory card B and replace it with memory card A. Go to the "Skills List", find the Dragon Balls, and use them on the desired character.

5. Return to "Trade Skills" and trade the Dragon Balls from the memory card C to memory card A.

6. Repeat steps 1, 3, 4, and 5 until you have all breakthroughs for every character.

Frieza's Space Ship Capsule
Get 12,000 Zenie go to "Recommended" in Mr. Popo's shop. When you see Frieza's Space Ship. pay the 12,000 Zenie. This Capsule takes three spaces in Frieza's slot. When you die, Frieza's Space Ship appears and restores everything. It also transforms you into Cyber Frieza.

Play through the Namekian Saga under the hardest difficulty setting and defeat Frieza at all times without losing once. The Capsule at the end should be Frieza's Space Ship.

The Legend Of Mr. Satan Capsule
Unlock Mr. Satan and go to the Mr. Popo's shop. Buy the "Advanced Tournament" Capsule and the one that appears next is "The Legend Of Mr. Satan". It is a new fighting mode, where you recreate the events that the public believed happened during the "Cell Games Saga".

Super Trunks 2 Capsule
There is a capsule to get Super Trunks 2. It is stronger then Super Trunks and is very helpful when fighting in the tournaments. You can purchase this from Mr. Popo. The "Recommended" capsule section is the best place to find it. Exit in and out of the purchase screen and the recommended capsule should eventually appear as Super Trunks 2.

Advanced Tournament Capsule

Red Capsule
On world championship mode, if you win you get 10,000 Zenie and second place gets you 5,000 Zenie. This is useful because when you go to the shop and buy the Red Capsule, you will get some very good moves such as Super Saiyan Trunks, Kamahamaha for Krillen, and even Super Saiyan Level 2 for Gohan.

Burst Zone
When fighters simultaneously connect with an Energy Punch, you enter Burst Zone. You will know when this is happening by the speed at which both warriors are attacking and blocking. Rotate the Left Analog-stick as quickly as possible. If you are the fastest, you will deliver a powerful knock-back attack on your opponent upon exiting the Burst Zone.

Easy transformations
For easier transformations, enter the options screen. Select the controller option then move over to "Costume". Hold L1 and press Left or Right until you see P K G (the transformation buttons). You will now have L1 as a transformation button. Note: You can do the same thing with taunts; just press Left or Right or left until you find P K G E.

Easy win
To easily defeat an opponent, go to "Edit Skills" and give your character a Viral Heart Disease Capsule and a Vaccine Capsule. The Vaccine Capsule negates the effects of the Viral Heart Disease Capsule on your player, and only your opponent will get their life drained.

Fight through the story mode and/or the tournament mode until you can get the Senzu Bean, Viral Heart Disease, Vaccine, and Kamehameha skills. Equip all four skills on Goku, Gohan, or Krillin. When you now fight in a duel, allow your opponent to knock your health down to zero. By this time, the Viral Heart Disease should have depleted his health down to half of the last bar. The Senzu Bean will replenish all of your health and energy. Finish off your opponent with a four-punch combo and a Kamehameha.

Go into the options menu and set "Difficulty" to "Very Easy", "Com" to "Very Weak", equip the Vaccine, Viral Heart Disease, and a Senzu Bean, Set the time limit to 30 seconds.. When the match starts, dodge for the first fifteen seconds. The last fifteen seconds should deplete your opponent's health. When the clock reaches zero, if you have not been knocked out of the ring, you will be declared the winner.

Restore life
To get life without going into the rejuvenation chamber on Namek, go up closely to the chamber without going in. You should see your life bar fill.

Powering up
Hold X and tap Back(2), and hold Back after you tap it again.

Ki Ball tennis
This has no purpose other than a laugh, and will not unlock anything in the game. Enter practice mode (or two-player duel if you want to play with a friend) and choose your characters and stage. When the fight starts, put as much distance between you and your opponent as possible. If in practice mode, set the opponent's action to Deflect-Back at the pause menu. Once you are as far away as desired, launch an energy ball by pressing Circle. In practice mode, your opponent should knock it back at you. Just before the ball hits you, press guard (X) and if it timed correctly, it should be reflected back at the opponent. In a two player match, you can play it like a proper game. For example, flip a coin to see who serves (launches the energy blast). Set a score limit. If the Ki ball is knocked away, hits, or is hit by another Ki blast, whoever reflected the ball last gets the point.
