Kind of an old PS2 game, I know. But I did a lot of research through gameplay and here's what I got so far!

Dragon Balls Quick and Easy
{Dball}
Having trouble getting the Dragonballs? It can be pretty frustrating. Fortunately, there is an easy way to get them. Go to Dragon Adventure and choose the Saiyan Saga. Then go to the event titled Training in Heaven. Go to the yellow dot at the Southern Capitol. You should see General Tao. Fight him, and bust through the buildings, cancelling Lock On when you Lock On to him. Eventually, you will find a Dragon Ball. Get it, then beat General Tao. Keep doing this until you get all 7. Save it, then go to Shenron, and you can load it if he doesn't offer you the item you want.

Double EXP for characters
{x2exp}
In Ultimate Battle Z mode, pick any of the Tag Team roads. When you are asked to choose your characters, pick the character you want to double the EXP gained from the battles you'll fight on the Tag Team road. Make sure to choose custom, and make sure that the character has Z-items equipped that can be leveled up with EXP. When asked to pick your second character, just pick the same character again, along with "Custom" just like you chose the first character. Now, when you win a round, you'll get double the EXP!

Halo Goku and Vegeta!
{Halo}
Fuse potara purple 5 and 6. It will be a yellow potara. Use this yellow potara at goku or vegeta potara list to get them as a halo character.

Level 160 characters easy!
{160A}
first of all you need to get either 5 "title tenkaichi's" or 5 "kiss of #18's" each one adds 4 levels to each attrinute, so if you put on all five that means all of the attributes will be maxed and you also have some empty slots to add in other items. Personally, my best line up is SS4 Goku/Vegeta/Gogeta with 5 "kiss of #18's", "Genuine power" and "Halo".
I didnt try other characters. So try it for your self.

JAPANESE VERSION FUSE CHARACTERS.
{JapPotar}

I hope this will help you to unlock the characters you are still searching.

Tip 1: before fuse go to baba store and buy the first purple potara. something called Z Item Fusion, or somethin' like that. This potara lets you fuse potara 1 time so be sure to buy as many as you can.

Tip 2: First the base form before you fuse the transformations.

Fox Mask
{Fox}
If you are having trouble finding the Fox Mask to unlock Grandpa Gohan here are the instructions on how to find it and get it.

Fox Mask, is located in both the Android and Buu saga's. In Android saga chapter 17, and Buu saga chapter 11. Go to the yellow dot at the Mountain Road, Yamcha will be there, beat him to get Fox Mask.

However Yamcha will be Lvl.228 so make sure you lvl up your character a bit. Also play it while in the Buu Saga as it is easier. Hope this helps.
