Breakthrough Capsules are rare, untradable items. Breakthrough capsules will unlock every Red and Blue capsule (and where applicable, the attacks at full power as if several of that attack capsule were equipped) at the same time for that character. The Breakthrough capsule takes up all 7 slots for the capsules though, meaning you can't equip any of the Green capsules with it. The Breakthough Capsule can only be obtained by collecting all 7 Dragonballs and summoning the dragon (to summon, go to the capsule list, when you go to the Dragonballs, it will ask if you want to summon Shenron, say yes to summon). All the Dragonballs are obtainable in Mr. Popo's Shop for 8,000 Zenny. They are only found as a Recommended Capsule (Dragonballs will be displayed as grey capsules in the recommended section), as a Random Capsule for 3,000 Zenny, or at random as a prize for completing a level in story mode.

How to unlock the hidden characters.

Play through the Namekian Saga under the hardest difficulty setting and defeat Frieza at all times without losing once. The Capsule at the end should be Frieza's Space Ship. When you die, Frieza's Space Ship appears and restores everything. It also transforms you into Cyber Frieza.

On the loading screen, a dragon radar with the logo of the game is flashing in the bottom right corner. You can control the movement of it's light by pressing left or right with the control stick.

In order to play a darkened stage when you choose where you want to fight instead of using the A button use the Y button. Of course not all stage will have a night version only a few.

This glitch only works with one of the characters who can use the Senzu Bean, Saiyan Heritage combo. (Goku, Kid and Teen Gohan, Vegeta, Trunks, Raditz, Nappa, and Cell)

Select one of the characters above and make sure that they have an empty capsule tray. Then, put down at most three capsules. Then, put down 1/3 Senzu Bean and then Saiyan Heritage. Then, put down a capsule that will take up the second to last capsule slot. Finally, replace the 1/3 Senzu Bean with a full one.
