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 a while.
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 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. 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 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 L and hold B to hit him with a Kamehameha Wave. Keep doing this until he is defeated. You should not lose any health by doing this.
Do a Warp Kamehameha
You must have teleport, and Special Move. Next, Lock on to a character. Start the Special move, and Charge it. Before it fires, Use teleport. You will end up behind your target. Release to Fire your Warp Kamehameha.
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 B. When game play slows down and your character starts charging up a blast, press L and put your aiming reticule on your enemy. Press Teleportation (Black). You will teleport directly behind the enemy while you are still charging up. Once you have appeared behind the enemy, immediately release B 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. 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.

Stronger/Extra Smash Hit
This is realy easy to do first you have to have the upgrades upper cut,smash,and teleport.The first thing is to get into a fight then hold the block button untill an oppnent comes close to you use the upper cut then use smash while the person is in the air as your oppenent starts to get close to the ground your fighter will quickly fly down and knee him before he hits the ground and as soon as your fighter knees him use the teleport skill and your fighter will move a slight bit higher in the air on the opposite side and hit him with more power than the regular upper cut + smash combo.This is going to take practice but its well worth it because this will come in handy on strong people or bosses.This makes a good stuner to start up a special ki attack.
