you need all the dragon balls to get either of the dragons

shenron

if u get all the dragon balls with gt characters u can battle the red shenron trust me i
know these things when u awaking him he'll say "do u wish to battle me!?" if u say yes
he'll morph into a rendom character except he has a tail and wings he'll have 80,000 hp
youll have to have 60,000 so good luck
