i personally would like to see more attacks for frieza, buu and also cell but for cell you should replace frieza disk with destructo disk and add ki blast cannon from tein. for frieza a charge laser would be good or a ball to beam attack. as for buu more rapid fire mouth blast and also a type or kamehameha as was shown in the series or possibly the super ghost kamikaze attack that he uses as super buu that uses kamehameha and masenko. also all characters should be able to do an attack like Vegeta did against buu but there should be a time limit on when you can respawn and also have full energy and transformed.
