Yup DBZ had one Super Sayin in the last 1000 years, and ppl thought Goku did it because he was pure of heart. Then we see Vegeta became one based off him fighting for his life (also a desire to be great) and like the Super Sayin it appears that the True Alpha (to date) is derived off a need/emotion.
