I'll say it. This is, by a longshot, my favorite moment in anime so far. You can feel Vegeta's rage over his loved one being hit.
You know that if it anyone else that hit Bulma, other than Beerus, they would be on a one way trip to Otherworld.
This is just one moment, out of sooo many in the Dragonball/Dragonball Z franchises, that is simply awesome to watch. (Unfortunately I do have to admit to GT having awesome moments to...)
