yes but he ceaps it a secret;)
No! the only non pure sayain to have a tail was Gohan. this was explained off by saying that the tail is a recessive trait and it was very uncommon for non purebloods to have it. mainly the writers thought super sayains were enought o work with and did not feel like doing another great ape transformation
Yes he was during the battles with Super 17 and Omega Shenron.
That earthlings name is KRILLIN is what I beleive is goku's awesomest Line because on the game burst limit he says that and becomes a super Sayain
gOhan
No I don't believe Gohan was ever spanked at all entirely through all of DBZ.
No he almost dies in Majin buu saga but he does not have a halo
Goku becomes super saiyan 2 when he is training in a special room at Kami's lookout. It allows a year to pass in the room, while real time in the outside world is just a day. He acheived SS2(Super Saiyan 2) right before he battled cell. So did his son Gohan. Even though Goku was stronger than ever at that time, Gohan was stronger than Goku, achieving SS1 and SS2 in the special room. Gohan was the first one to go SSJ2. Goku became an Ultimate SSJ in the Hyperbolic Time Chamber. Goku went SSJ2 for the first to battle Majin Vegeta, which was about 7 years later. Gohan went SSJ for the first time in the Time Chamber, and SSJ for his fight with Cell.
No because he is not a pure Saiyain like goku and vegeta
Yes but not in the real future where Goku lives from the life threatening disease.
no,piccolo also trained goten and trunks how to fuse.
Of course! Gohan could become Super saiyan 2 in the cell saga after android 16's farewell and destruction, then another loss, provocated or not, he could go past that evel and certainly attain super saiyan 3!
No women ever played in a Super Bowl game.
