Kaboom!!!

[Hellspawn28]

Most people believe Roshi's Moon feat is Inconsistency since stronger characters never show that level of power until later on when Piccolo blow up the Moon with a simple ki beam against Gohan's Oozaru form.

[Savage68]

That doesn't make Roshi's "Moon-busting" feat inconsistent, because this happens all the time in DB, and comics in general. The Earth is protected by a sturdy set of plot armor. Freeza can destroy Namek at no more than 70% of his power, but a ki blast from Super Buu 2 fails to make a notable dent in the Earth's surface. Toriyama just can't have the domicile of DB's protagonists being leveled all over the place, can he?

Piccolo Daimao was able to wipe out an entire city with no effort, right? I believe he could have destroyed the Earth, if he wasn't planning on ruling it.

[Bussani]

If my math is right, the Earth's Gravitational Binding Energy is about 1821 times greater than the moon's. If battle powers are a linear scale and Roshi's moon-busting Kamehameha was at 180, that means it would take a battle power of around 327,780 to fully explode the Earth in a dramatic, Death Star style kaboom. Considering first form Freeza's supposed battle power and how he blew up Planet Vegeta with one finger, that...kind of makes sense? Of course, if you had the energy to destroy the moon, that would also be enough to destroy all life on Earth's surface if you felt like it, so Piccolo Daimao certainly could do that! I'm sure Vegeta's 18,000-24,000 would be enough to rearrange the Earth into a molten ball, too.

PS: Don't take the above too seriously. I know looking at it this deeply is ridiculous. =P

PPS: I wonder how right my math actually was...

[Perfect]

There's a difference between adding power to an attack and actually powering up. >.>;;

^Directed at whoever said something about Freeza not being able to hold back when clearly he can put minimal amounts of chi into an attack (as well as any other character) that would do little more than blow a huge boulder apart.

He destroyed the city's center, or it's capitol.

Freeza was at 50% of his power, when he blew up the core.

[Shoryuken]

What about Freezer's daichiretsuzan (大地裂斬 Earth Fissure Cut) couldn't it technically in the hands of a more powerful user be used to cut planets in half? If so Freezer did display strength enough to cleave large areas of Namek with a single swipe.
Hell, the technique is even known as "Planet Cutter" (惑星切り Wakuseigiri)

[Herms]

In the Bouken Special, there's this series of rough sketch comics by Toriyama where characters explain how to perform their special attacks (Hujio and I have been wanting to put these up on Kanzentai for a while now, but we never quite get around to it). One shows Tenshinhan demonstrating the Kikoho, but he accidentally cracks the Earth in two. "Maybe I overdid it a little", he says sheepishly. I don't know how "canonical" this would count as, but I thought it was funny.

[Senzu_Bean]

^ I really have to see that.

[painfuldeath]

I think destroying a planet has less to do with power than how its done. Blasts directed towards the core in a focused form are likely enough to destroy a planet. It is possible that even Roshi could destroy the Earth had he directed his Kamehameha towards its core.

[Savage68]

The only time that core-busting was suggested to be the cause of a planet's destruction was in the Namek arc, and in that scenario, the perpetrator (Freeza) later proved that he was holding back.

That doesn't really make sense from a real world perspective, but...neither does Namek exploding because its core disappeared. So yeah, that's a possibility.

[Savage68]

From a real world perspective, it takes just as much energy to destroy Earth's core as it does to destroy the planet, anyway. And there's no reason to think that a profoundly sturdy mass of iron would detonate like a bomb just from being molested by a speck of energy.

[Bussani]

I'm not sure I follow you here. How would you define "destroy" in this situation?

But yeah, that's what I meant, too. The planet's core isn't set to go off like a bomb when hit, and even if you could cause a massive explosion down there, all that mass-energy has to go somewhere. It would either be enough energy to blow the planet to pieces (which it wouldn't be if you only had enough to blow up the moon), or it wouldn't, and the core wouldn't go anywhere because...well...the rest of the planet would still be wrapped around it. Which might be what you meant above, anyway.

But the Dragon Universe doesn't necessarily seem to run on this logic, especially when you look at what Freeza did to Namek. So I dunno.

[powerupguy]

I bet Kuririn could Kienzan the Earth in half!

[Bussani]

I bet Kuririn could Kienzan the Earth in half!

Maybe--but the gravity of the two halves would just hold them both together!

Maybe it would throw the Earth's rotation off course!?

[Rocketman]

I bet Kuririn could Kienzan the Earth in half! :D

It would not.

Well, from a real world perspective nothing in DB would make sense. The Earth's core is molten metal, blasting through it would require enormous energy. It just makes no sense to try and reason with real world logic. A planet wouldn't just explode into space dust out of nowhere, it would probably implode on to itself, then have its chunks slowly drift away as the gravitational force decreases.

Still, is there any official size correlation between the DB Earth and Namek? It seems to me that Namek is SMALLER than the Earth because of the way its depicted during fights and its shorter year. If that is the case then it would take more energy to destroy the Earth than to destroy Namek. That said, I still think its more of a matter how you do it then brute force. Buu exploded the Earth by expending all his energy to explode himself. Frieza destroyed Namek by busting its core. I don't believe Frieza could have done the same Buu did as he uses a specific technique to get to the core. He doesn't just blast the planet.
