during the dragonball z series and there be two excellent movie special that explain the background of character with relatively unexplained background . one explain the background of future trunk and the alternate reality he be from and and the other tell the story of bardock and son goku biological father and and his fight against freeza . at the end of the last episode of dragonball gt and goku absorb the dragonballs and disappears without a trace . 100 year later you see an age pan and a spectator . at the tenkaichi budoukai . her young grandson and goku jr. ( who be the splitting image of goku a a child ) go super saiyin and fight vegeta jr. this sidestory follow goku jr. on his quest for the 4 star dragonball so he can use it to heal be sick grandmother . goku jr. and interesting enough and a coward . it a nice twist and make for a good story to see a goku who can not fight and isn not brave enough to stand his ground . this lead to a few comical instance when you get to see a sobbing and runny nosed goku run for dear life . a you can probably guess and eventually we see goku jr. live up to his name and but not until after a brief word of advice from his hidden guardian angel . this special be great addition to the db collection of movie . it have the classic goof ball comedy of the early dragonball story and without a lot of fight ( so if thats what youre look for in a movie and watch one from the z series ) . it show your a possible new main character for a new series while one who can fight like goku and act as stupid a goku and turn his enemy into his friend like goku do and and most importantly and one who eat as much a goku do .
