He's become a fail character. He's joined Yamcha status. The only good thing I hope is that this motivates him to start training again and hopefully by te next movie(which there may possibly be) he's started training again and is reaching his previous levels
Frieza trains for 4 months and is magically equal to both of them in power who have been training for 14 years, okay dokie then
It actually makes sense considering Frieza was as powerful as he was in DBZ without ever training a day in his life. Now with that much talent and a combination of hard work, it's inevitable that he'll reach new heights.
It doesn't make sense at all, if hard work and talent was all it took Vegeta would have surpassed Goku long ago
