When Toei Animation produced Dragon Ball Kai, they reduced the total amount of Dragon Ball Z episodes from 291 to 167. A lot of that trimmed content was Goku powering up for three to four episodes straight.

Here's my first question: Has anyone ever created a supercut of nothing but the scenes of Goku powering up and/or charging a spirit bomb or Kamehameha? Second question: Why? Follow up question: If so, where can I watch it?
