Your character's journey begins at a child phase. Much in line with the traditional family spirit of the DB franchise, your character progresses in age as it levels. But rather than it being gradual, at level 30 you must undergo a quest in which brings you to your adult potential. It is unknown whether or not this quest is mandatory or not. However it is speculated that those who chose to stay children will be at a disadvantage. Those who chose to progress gain benefits in both skills and stats. The aging aspect is speculated to also play into one of the possible ends to your characters life. It is unknown if death by old age is probable, but it is worth mention since aging is just another part of the game.
