Captain Cadaver said:It was a fairly forced way of Toriyama trying to say that he's changed, considering his plan doesn't make much sense. We're given no inclination Vegeta knew how the Genki-Dama worked (hell, we have no evidence he even knew its name in the Saiyan Arc), yet he banks everything on this attack just because it really hurt him at a time when his full power didn't even measure up to 1% of his current self and just assumes one with more Genki will do the trick
