Throw someone, then when they go flying, do Galick Gun, etc. and it will kill them.

Easy energy blast hits
When fighting a henchmen or Boss, get him within the view of the screen. You can do this when you are on the ground or in the air. Hold Circle when game play slows down and your character starts charging up a blast, then press L1 and put your aiming reticule on your enemy. Press Teleportation (R2). You will teleport directly behind the enemy while you are still charging up. Once you have appeared behind the enemy, immediately release Circle to blast your enemy at point blank range. If you want to be reckless, charge another one after he falls to the ground from the last attack. Teleport behind him and blast him again. You can do this repeatedly. Note: It is easier to do this when the enemy is distracted by charging up his own blast or doing any other attack that he may be trying to perform. Just hit him with this before he can make it successful.

Easy practice
Set the game on two-player mode. Have the second player be Goku or Vegeta. You will win against him because he cannot attack.

Play as same character in Pendulum mode
While at the character selection screen in Pendulum mode, have both players highlight the character you which to be the same as, then press X simultaneously. If done correctly, both should say their names at the same time. Note: The timing must be precise.

Warp Kamekameha
To do a Warp Kamehameha or any Warp Ki attack, when charging it lock on to your opponent and teleport.

Instant Transmission Kamehameha
To do this, Teleport is required. When you are far away from your opponent, lock on to them and start your special technique. Immediately before you launch it, press R2 to teleport directly next to your opponent. A better way to do this is if you have uppercut; hit you opponent into the air, start your technique, and teleport right next to them. By doing this you will have a clear shot and should not miss. This is a great way to defeat Bosses and can be done be anyone.

Turn invisible
To turn invisible you must be fighting a Boss. When the boss punches you into the air and hits you back down, before he slams you back down press X to slam him down instead. Alternately, start charging Ki and teleport. Fire Ki blasts and jumping, all while charging. If you wait long enough you should turn invisible.

Hit Dende
In Tyranny Of Frieza you can hit Dende with Ki balls or a special move.

Protecting Goku
With two players, while one is fighting the Android, have the other person stand in between Goku and Dr. Gero. The Ki Blasts that Dr. Gero shoots should hit the other player instead of Goku. Make sure that they are a short distance away from Goku, as the explosion from taking the Ki Blasts can also hurt him.

Warp finishing move
When locking onto an opponent with any character, while charging for an attack, teleport in front or in back of your opponent and attack.

Goku's finishing move
Press Triangle(5).

Defeating Bosses
When fighting a Boss, have a special move, teleport, and a good combo selected. Run up to the Boss enough to teleport behind them, then do a combo. When he or she gets thrown away, lock on quickly and hurl a special move to cause maximum damage.

Defeating Android 17
To defeat Android 17 in Trunk's Saga, dodge his blasts, then press Punch four times each round.

Defeating Android 18
To defeat Android 18 in Trunk's Saga, dodge her blasts, then press Punch four times.

Defeating Captain Ginyu
When fighting Captain Ginyu, he will dig underground most of the time and attacks from underneath. To avoid this, get up in the air and stay there; Captain Ginyu cannot fly. When you are up in the air, you can charge your Ki or a special move then keep launching attacks at him. He should be defeated after awhile.

Defeating Cell
Once in SS1, do only simple combos with a lot of buttons involved; the more buttons the better. Try using the first two combos that you learn. Note: You must have Combo Breaker. Try not to use Ki moves unless you have to; the longer you must charge, the more open you are to attacks.

Defeating Frieza
When fighting Frieza in Tyranny Of Friezam, he will Shoot Death Balls at you. Either dodge them, or when you are close to him, punch or kick him. He will dodge your Galick Guns by teleporting. Just punch him until Piccolo arrives.

Defeating Vegeta
When fighting Vegeta, stay in the air the entire time. Dodge his Galic Guns. When he uses his other attack, it will only affect you if you are on the ground. While that attack occurs, Vegeta will be vulnerable. Lock on to him with L1 and hold Circle to hit him with a Kamehameha Wave. Keep doing this until he is defeated. You should not lose any health by doing this. Additionally, fly in the air so you do not get hit, then stay in the air. Hold Circle, then when Goku says Kame, release Circle. It will almost always hit him. Also, dodge his moves and get up to him. Keep attacking with Square(2), Triangle(2). Do not stop doing this to prevent Vegeta from guarding. Sometimes he will make a quick guard and start beating you again. Note: He is very fast.

Defeating Nappa with Gohan
Fly while shooting Mesenkos at Nappa. Nappa will eventually start shooting blasts of energy that paralyze you. Quickly dodge them and fire at him.

Defeating Freiza with Goku
When fighting Freiza as Goku, you can only hurt him when you are a Super Saiyan. When he charges up his Death Ball, use the Quick Teleport (if purchased) to get to him and deliver the blows to hurt him or charge up your Super Saiyan meter. Try using only punches and kicks, as he will dodge the Kamehame Wave. It will only hit and hurt him if you are Super Saiyan and if done while he is charging up his Death Ball.

Defeating Perfect Cell with Teen Gohan
Keep hitting him until the Ki bar for Super Saiyan is full. Then, turn Super Saiyan and keep hitting him until you have filled the Ki bar for Super Saiyan 2. Finally, when you turn Super Saiyan 2 attack Cell with Masenko, but first lock on to him with L1. If he teleports behind you, use a combo. Note: Do not waste your Ki on Cell.
