Dragon Ball Z : Battle of Gods [2013 Release]

Why is it that defeating Freezer was such a big deal? Majin boo alone defeated the 4 supreme Kaio's of the universe, but this guy gets interested in Goku because he defeated Freezer?. Considering its said this guy wipes the floor with Goku on SSJ3, this guy must be close to SSJ4 lvl, then why the pineapple would he act like freezer was such a big deal?.

 Spoiler

I guess it's because Bills and Wiss have been in hibernation (?) for 39 years, or some stupid number like that, and Majin Buu was thought to have been sealed away permanently. Frieza has been the universal overlord for a very long time - since before Bills and Wiss went into hibernation or whatever. Hearing the defeat of Frieza, Bills wants to destroy Goku, because there's an overabundance of "good," creating an imbalance in the universe, apparently.

this guy must be close to SSJ4 lvl

Actually... I haven't seen any confirming sources, but I've heard that V-Jump stated that Bills is about as strong as an Ascended Saiyan form (SSJ2) of Gogeta, which has never made an appearance anywhere, which is magnitudes stronger than Super Saiyan 4 in GT was.

Also, apparently, Wiss is even stronger than Bills. And according to some sources that have seen a preshow of the movie, there are 12 universes in Dragon Ball and Bills, the God of Destruction, resides only in this universe and that he is the weakest of them all. This could be opening up to even more Dragon Ball content in the future.
