Dragon Ball Episode 125

You are an fool if this is what you came up with after watching the episode. While Dragon Ball uses a lot of different cultures to create its world the main culture used is Japanese. While the concept of there being one all powerful God is very popular across the world, most Asian cultures don't believe that there is only one God. Kami it self is a word used to describe spirits, natural forces, or essence in the shinto faith, it is only some times translated to mean god or deity.

...what? your belief in god has nothing to do with this...

When we first met him I had no clue he would be so strong.
The way he walks around or sits here and there. No hint at all that he would be so powerful and Goku feeling cocky leaves himself open to fail.
