Press are and x at the same time while choosing a character ,like goku in super saiyan,to start transformed.An example, by doing this you can start with goku in super saiyan form

Usually there is a chance that your ultimate blast or regular blasts will hit, by a higher chance of missing. An easy way to get a direct is by stunning your opponent using a gaurd break attack which can only be used with an aura Burst. After the gaurd break your opponent is stunned and then your opponent is vulnerable to any ultimate blast.

P.S. Suggest not to use this tactic with Majin Vegeta.

To get Janemba you must finish the dragon road

To get gogeta and vegeto take different pats in dragon road mode in chapeter 5

Sorry about my last submission it was wrong.
Krillin can also use the Extra Damaging moves.
It's the same combo as SS2 Gohan and Broly Start the ultimate attack and press O (E). The characters are Broly, Krillin, SS2 Gohan, and SS3 Goku.
Sorry about that, I will try and get my further submissions correct.

To get alot of items to personalize your card all you have to do is click on Z trial mode and click on survival mode and defeat as many opponents as you like and the number that you defeat will be the number of items you will recieve.

P.S.
This game rocks!
