There is something I do not understand when it comes to Kid Buu, and that is how did we get from Majin Buu (Fat Buu) from our first encounter with the Buus to Kid Buu at the end. The way I look at it is this, Majin Buu creates Evil Buu who absorbs the latter turning into Super Buu. Goku and Vegeta remove everyone from inside Gohan absorbed Buu which reverts him back to Super Buu. And then when Vegeta removes Majin Buu we get Kid Buu? Algebraically speaking it does not make sense for Kid Buu to come out at the end of all the transformations. If anything it should be Evil Buu again.
Here is a formula that I have made, maybe I am looking at it wrong, or have the wrong variables.
What do you all think?
