Why doesn't a villain ever try to blow up the sun?

[Kamiccolo9]

Seeing as how the Moon has been destroyed in DB not once, but TWICE, and these things didn't happen, your point is null and void.

THAT is my point.

I feel your pain. I really do.

Well, in case anyone missed it, and attempting (probably in vain) to get back on topic here, ABED mentioned on page one that the Vampire Lucifer tried to blow up the sun in Dragonball Movie 2: The Sleeping Princess in Devil's Castle. It was his main ambition, and he even had a megalithic cannon set up to do just that. Just as he prepared to fire, Goku blew the platform out from under him with a Kamehameha. The cannon fell into the pit below, now vertical, and aimed away from the sun, it fired into outer space and subsequently vaporized Lucifer in the process. It really is a cool movie, and one of my favorites.

Question asked and answered, I guess you can go back to your "canon" arguments, even though the "Cannon" in question has been now answered in a bit more detail.

I had forgotten about that. Thanks.
I know Cooler thought about blowing up the sun after being blasted into space (at least in the dub).
