Defeating the Oozaru

Easy Dragonballs
Fight in level in Z Battle Gate at Kami's Lookout. For example, play as Krillin vs. Yamcha. During the fight, go over to the main building and put it between you and the enemy. When you fire your finishing move, you will destroy the building. Go over and look at the rubble. There will be a column stump remaining in the middle, and a Dragonball on top of it. It does roll off -- if it is not on top, then it is somewhere on the ground. Quickly grab it and make sure you defeat your opponent, or you will have to get the Dragonball all over again. All seven Dragonballs will appear one at a time at this location randomly. Just fight in the level seven times to get a wish from Shenron. This is very useful, as every time you get a Dragonball and complete the level, you will also get another Z Item Fusion, which are valuable, and a random Z item. Do this as many times as desired.

In Story mode, select the Buu Saga and look for the level that takes place on top of Kami's lookout (SSJ3 Goten vs. Super Buu). During the fight, destroy the main building on top of Kami's tower. There will be a Dragonball in the rubble every time. Repeat this as many times as desired. Note: You must successfully complete the challenge each time in order to receive the Dragonball at the end of the match (for example, finishing off Super Buu with the Volleyball attack).

Go to the fight with Chiaotzu vs. Guldo. Burst through the few islands in the stage and locate the Dragonball by using your radar. Then, defeat Guldo. He is not much of a challenge. Repeat this to get all the Dragonballs.

Go to the Saiyan Saga and get to the part were you must defeat Krillan with Yamcha or vice versa. Go to the building in the middle of the look out (the biggest one). Destroy it and get the Dragonball there. Defeat the enemy and you will get the Dragonball at the end. Do this seven times (always a different Dragonball) to get all of them.

Go to Sayain Saga and Krillin vs. Yamcha. Blow up the big building and get the Dragon Ball, then win. Repeat this a total of seven times.

When fighting Super Buu in Buu Saga with SSJ3 Gotenks, the Dragon Ball is inside of the lookout house. Get the Dragon Ball and defeat Buu with the super move. Repeat this until you have all seven Dragon Balls. Keep doing this and you will unlock everything that requires a wish to obtain.

Easy wins
To win easily, just press Square then X. You will punch, then deliver a heavy blow leaving your opponent defenseless for a short time. Note: Sometimes very good fighters, for example Android #15 or #12 in Ultimate Battle mode, will break this combo. If your character is fast enough (try increasing the speed stat on your character's Evolution Z to help) and your opponent is a big character that will not be affected by normal punches and kicks or normal Ki blasts, you can land up to one attack from your character's full combo ability (the maximum is about five), then press X. You can get 99 hits if you are skilled enough. It will not count any more after that, but the damage will still be rising.

Easy World Tournament win
Select a character with high speed dash or a move that works similar to it. At the start of a tournament fight, dash toward the opponent, attack a few times, and knock them back. When they are near the edge of the ring, do high speed dash. As soon as you finish the attack, hit them with Ki blasts. Their feet will instantly touch the ground allowing you to win easily. Additionally, play as Chiaotzu. Rush at your opponent, then do four regular attacks followed by four Ki attacks. If done fast enough, your opponent will just fall off the stage and you will not lose any health.

SS4 Goku combo
While playing as Super Saiyan 4 Goku, instead of using just 10x Kamehameha use the following combo. Increase to maximum power and have three favorite technique bars full. When you are at maximum power, find a good time to attack your opponent (for example, when they run away to charge or when they are close to you). Use Instantaneous Transmission (L2 + Circle) to warp behind your opponent. As soon as you are behind your opponent, press L2 + Down + Circle to use 10x Kamehameha to hit your opponent from behind. This attack is not stronger than the regular 10x Kamehameha, but it is harder for your opponent to dodge.

Strong combo
This trick only works on weaker enemies. First do four normal attacks, then do a stun with dash and repeat. If done correctly, it can result in a 75 or greater combo.

Stronger Ultimate Gohan
Equip Ultimate Gohan with Speed +6 and Attack +6. If you are fighting a smaller character such as Krillan or Goten, a full 7-hit combo does about 3,600 damage. However if you are fighting someone very tough such as Bojack, Broly, or Cooler, the damage will reset because of the fact they are so tough. You will do about 2,600 damage. Also, if you press Square about four times, X, then Square a few more times, the attack damage will almost triple Gohan Ultimate's regular 7-hit combo damage. The regular finishing move does 15,500 damage and his ultimate attack does 245,000 damage.

Wishes

Wrong name
When you fight with Master Roshi in Tournament mode, the tournament announcer instead calls him "Contestant Turtle Hermit". Additionally, when fighting with Tien in any mode, use Ki Blast cannon. When you do so, instead of saying "Ki Blast Cannon!", Tien says "Tri-Beam!", which is his super finishing move's name.

Wrong subtitle
In Z Battle Gate, on the Super 17 gate when you defeat him, he says "I should have been able to absorb all that". However, the subtitle reads "I shouldn't have been able to absorb all that".

Fight Nappa with Chaoutzu and kill him without using Farewell Mr. Tien. Nappa will say "You almost gave me a scare", but the subtitles read " Kch...That was a lousy thing to do".

Wrong voices
When Goku SSJ4 and Vegeta SSJ4 fight, if Goku wins he speaks in Japanese instead of English at the end of the match.

When fighting Super Saiyan Trunks (with the tied back hair) and he executes a Finish Buster, he says it in Japanese, similar to Dragon Ball Z: Ultimate Battle 22.

When using Long Haired Trunks, do his Burning Attack move. His voice will change to Japanese.

In COM vs. COM mode, if SSJ4 Goku fights and wins against SSJ4 Vegeta he will speak in Japanese after the battle, even if the Japanese voices are turned off.
