how do i unlock super
nova

how do i unlock uub

to unlock uub was easy for me

wat u do is play through du with goku all the way to kid buu

there u might want to safe just in case u mess up

go to the red dot

make sure u have spiritball, kaioken, supersayian 1 and wat ever else u want

go battle kid buu when he has half orange left go into hyper mode

u have to be normal or kaioken or this won't work

use spirit ball(it will say super spirit ball)

with the energy bar make sure u get more than kid buu

u kill him

it will ask u to save(ur choice)

then goku will be talking about to tourny in front of his house

go there skip the cut scene then fight uub(he is really easy)

then u have unlocked him
