Also, Goku points out that being able to turn Super Saiyan on command took him a great deal of work, and he had a year and a half to do it. I would assume that Vegeta was a Super Saiyan for at least 6 months, but I prefer the idea that he'd achieved it about a year into his training. It's all open to interpretation (unless you're a videogame called "Legacy of Goku 2" and screw things up just to get to the point faster).
Well, we do see Goku talk about needing training to control the activation of SSj - but we also see Gohan go, in less than a year - from not being able to transform, to transforming at will, to staying in SSj form all the time. Can we draw from this that more intensive training and/or greater power would make the 'training' of one's Super Saiyan ability to be quicker? Vegeta trains harder than Goku or Gohan (especially at that point) and was stronger than Goku and (arguably) Gohan while they were 'training' their SSj forms.
If Gohan could go from nothing to 'full power' in under a year, I think it's safe to say Vegeta could achieve control of SSj within a few months.
Of course, this could mean that Vegeta achieved SSj early or late in his training.
Also, let's look at when Trunks could have been conceived. We don't have a birthdate, so we'll have some wide margins - but bear with me.
May 774 (Buu saga) Trunks is 8 years-old. May 767 (Android saga) Trunks is 1 year-old. We don't know if his birthday was a week before, or 11 months before, so he could have been born anywhere between June 765 and May 766 - similarly, he could have been conceived between September 764 and August 765.
Future Trunks arrived sometime in August 764,so that gives Vegeta one year to conceive his son.
For the 'Super Siayan gene' theory to work, Vegeta would have had to achieve SSj within one year, at the absolute latest. He'd have a full year only if Trunks was exactly 1 year-old when the androids arrive. If Trunks was 1-year-and-3-months old, Vegeta would only have 8 months, if Trunks was a year-and-a-half Vegeta would have 6-months, and so on.
So, the whole 'gene' theory rests on the assumption that Vegeta could have achieved SSj in an incredibly short amount of time. Does anyone
honestly believe that Vegeta could have gone SSj within a year?
Consider this:
- While it was only filler (IIRC) that showed us Vegeta training and transforming in space, it makes sense. If Vegeta had transformed on Earth all the Z fighters would have instantly felt such a large ki. But, the Z fighters are shocked at the fact that Vegeta is a SSj when he fight #19.
- Vegeta would have trained in his Super Saiyan form after having achieved it. Not just to control the transformation, also as a sense of pride about having achieved it. If he'd have transformed into a SSj, as I said before, everyone would have felt it before he showed it off against #19. Again, more reason to think he trained off-planet until the androids arrived.
- Vegeta doesn't seem like the kind of guy who'd jaunt back from space for a booty call. Maybe I missed something, but I just don't see it in him.
Considering these points, I find it hard to believe that Vegeta could have fathered Trunks after becoming a Super Saiyan. It seems the most likely events is Vegeta trains on Earth, conceives Trunks, continues training in space, achieves SSJ, continues training in space, returns to fight the androids.
