Blast Off At The Speed Of Light! That's Right!
Whatever your take on the story, Battle of Gods made it pretty clear that both Frieza and Bills are aware of each others' existence, considering Bills anticipated Frieza might be a successor. I imagine the God of Destruction takes interest in planet-busting galactic realty outfits. The notion the Colds had some dealings or knowledge of either Bibidi or the Kais is not unimaginable. Good Intel is a form of power.Also I lol'd super hard at the part where Freeza says his Dad warned him about Majin Buu-- I mean, the premise of the Buu arch was that the events of Babidi vs the Kai's happened so long ago it might as well be the beginning of the Universe. It's absolutely laughable to think Frieza's Dad would know about a beast that existed before their species probably even evolved. Lolz
Frieza didn't even have a sparring partner to train with. This is a guy who spent most of the time curbstomping planets in his base form. He was basically in a tier of his own until SSJ Goku happened - and while I'm sure there were other powerful warriors in the universe, why would Cold Galactic Realty try and go after the strongest planet champions instead of the weakest?
