I was watch DBZ Kai on 4kids (not nicktoons) and It was playing the battle of goku and Vegeta and When he did his galac gun they called it galac BLAST.......
So later in the episode king kai said that all that goku had left to is a Spirit BLAST not bomb
Spirit bomb
Galac gun
Is that realy not appropriate
Also they dont change it in the Nicktoons version
