By completing missions. Depending on what rank you are (or level) you can do a mission- something like win 15 battles with Haku in your team to get Zabuza. When you do win the amount you're supposed to do, you will either complete a mission and/or unlock a person. Hope this made sense...it took me forever to figure this out!
no you can ' t do it , BUT you can unlock other things .
Aqua is one of the people from the other world and you can't unlock Aqua in bt3 there is only Pikkon.
It might be the two people you make in the art room or other people...
when you upload a flip on hatena it should say lock which means other people cant edit your flip when downloaded and if you tap unlock it means that other people can edit and upload it but hatena has a thing that when you upload a flip you cant unlock it again unless you upload it again

You unlock them at level 51. Although I have seen other people get them before I don't know how though.
you have to play story mode to unlock other characters
You start the game as Yoshi. He has to unlock Mario, who then has to unlock Luigi, who then has to unlock Wario. (See other questions to find out how.) If you have an Action Replay card, if you find the right codes you can play as other various characters. Although some people even say that Waluigi can be unlocked without this... but that's another story.
Hotweels games are good but to unlock them at first its simple but then it gets harder. You can also unlock other cool stuff.
unlock all the other characters first
ACTUALLY you can UNLOCK someone and that is black mage. To unlock him play 10 matches and probably win them
Yes you can use cheats ,unlock in rtwm or unlock in wwe universe
