Could Ranma ever stand up to Dragonball /DBZ ?

[antimatterenergy]

Ranma is trained enough more than enough really his hand to hand skills is probably better than any of the charachters in DB. What he lacks is training in building up his Ki and using his ki to enhance himself. As already stated Ranma is a novice ki user wheras most of the Dragonball characters have been training specifically to use they're ki for years. The DB characters training is mostly to build up ki strength and using ki. The training Ranma has had has made his ki stronger than normal people and has enhanced his physical abilities but training in ki manipulation, build up, and using it to consiously enhance yourself has not been the kind of training Ranma has had until very recently and unlike the DB charachters Ranma doesn't have people willing to train him for the most part. Genma didn't teach Ranma ki techniques, Happosai doesn't mean to, and Cologne only taught him a little and no more (didn't even train him completely in the Hiryu Shoten Ha). For the most part Ranma's use of ki is self taught. Also unlike many of the DB characthers Ranma isn't an alien that naturally has ki abilities or an affinity for ki usage.
Nuclear death frog many of the mentioned ways Ranma would fight are not overly out of characther. If Ranma knew he was so outclassed these are things he would do. Ranma has and will cheat to win. Ranma will manipulate people to get things. Ranma has used mind control items on people in the manga Ryoga to fall in love with Akari, shampoo to get her to go home. Ranma will try and get things to empower himself - noodle of stregth, magical dogi. Ranma has snuck up on people. Ranma has used magic on others - happosai used girl repelant. Ranma will use weapons if he sees an advantage to it - battle vrs Saffron. Ranma has no problem flirting with people to get what he wants. Ranma has put stuff in other peoples food - kunos and the pervert boy who wouldn't take his medicine. So those things are not overly out of characther becuase Ranma has done similiar types of things in the manga when the world wasn't at stake.

Bullshit.
Half the ways you listed are murder attempts, and some of the others are murder arrangements.
Ranma is not a murderer. If he were, he'd have killed Ryouga or Mousse or a bunch of other people long ago -- he's certainly had ample justification.

I wonded if Moxibustion would work on Saijins? if so he might pull a happosai and take them down that way. Well the Son family anyway, Vegita would probably catch him in the act... The Son family is trusting enough to fall for anything Ranma trys to pull.

[antimatterenergy]

I'm trying to point out that Ranma can be a threat to DB characters. I did not mean to imply that Ranma would generally use these tactics or even would only that he could, especially since he has used tactics similiar to them but never to a murderous level and if something important enough to him was at stake he may use these tactics. Really Ranma wouldn't be fighting most of them in the first place since Ranma rarely starts fights with others or attacks first and he would be below what they would consider bothering to fight. I would never write a Ranma/DB crossover to begin with because of the massive power difference.

[WG_Writer]

I agree with that, but there was one Ranma DBZ cross that I liked for realism. Vegita destroyed Earth with Ranma at the epicenter of a blast, Ranma never even saw him. (forgot the name)

[Screwball]

Okay, I'll agree Ranma could be a threat, but only in an assassin-like way, not in a stand up fight.
As for crosses, I'm not fond of DB crosses, since they invariably either massivly overpower the other side, which isn't fun, or are massively overpowered themselves (I once saw a Culture/DBZ cross. Poor, poor Goku...). There doesn't seem to be anyone in the same category as DB.

Actually, I think that was during one of the fights in the series, and Ranma (and Tokyo) just got caught in the blast. Can't remember where I saw that one, but the author said he based it on one of the fights where Vegita's blast is shown to carve a (huge) trench in the Earth.

If you convinced the Z fighters to hold their power levels down to near Ranma's, he might be able to take them in a match of skill on skill. At their normal power levels, it doesn't matter how much more skilled he is, any one of them could kill him with one punch, while he'd have to pound them for hours before they'd get more than a mild bruise.
A good analogy might be the difference between attacking a tank driver with your bare hands and attacking a tank driver bare handed while he's driving the tank.

DBZ predates ranma (I think) and as such he couldn't be in it. But I refer to a Short spam fic written with just one scene... I will see if I can drag up the link.

I agre with bissek. On terms of skill, spotting openings, and the like, Ranma is simply better. The "training" done in DBZ is usually "be able to do more damage/move faster" type of training. Let's take Piccolo's split-self training. Yes, he can train himself to be faster and stonger by training against himself, but there is no way he can learn new techniques from his opponent, who does not know more than he does. Or the training Goku undergoes in the spirit realm during the Vegeta arc. Yes, he's stronger and faster... but he didn't learn how to _fight_.
The sheer power of the DBZ characters is insurmountable for Ranma to overcome. Even in the DBZ universe, humans have an upper limit to what they can do. Given access to the training methods (such as increased gravity) and enough time, Ranma can _probably_ match the other human characters, but absolutely never the saiyajins.
Reminds me of that SM/Ranma/DBZ crossover, where female Ranma comes back in time to train the SM characters to fend of Vegeta. It was a good fic, but even then the Ranma/SM cast were still overpowered, and still underpowered compared to the saiyajins.
The moxibustion would probably work, but I'm willing to bet it would be in a different spot (different anatomy and all that).
Assuming that Ranma already has chestnut fist, perfect shishihokodan, hidden weapons, tiger's bullet, hiryushotenha:
Genma's secret techniques would put Ranma on kulilin's level, prior/during the vegeta arc. Kulilin has demonstrated similar attacks, but would still be physically stronger and faster. Invisibility might help, up until a DBZ character uses an area attack. Ranma's invisibility also doesn't grant incorporeality -- he'd still displace air, and I wouldn't put it past the DBZ characters to use this as part of their ability to detect unseen/illusionary opponents. Super Soba and Battle Gi will put Ranma solidly on par with the human characters on terms of strength and speed during the vegeta arc, but not energy attacks.
While Pale Wolf might describe "undbeatable" as "not beaten yet", I subscribe to the "unless proven otherwise, then it is". I'm willing to bet focused beams can still be dodged, and straight up blows can be misdirected. However, I doubt it if even Mark of the Gods will save Ranma from an area attack, and likely it still won't give Ranma the firepower to actually hurt the DBZ characters.

That fic is Savior by Michael Fetter.

The funny thing is, most of the DBZ characters don't strike me as particularly skilled anymore. Sure, they've got power in spades, but they never seem to be able to wield it skillfully. They don't win by being a better martial artist - they win by being stronger and more powerful.

[Ninsaneja]

I had a fic where Ranma used variations on the Hiryu Shouten Ha as an energy drain to bring DBZ characters down to his level, but it really, really sucked (mostly because I basically know nothihng about DBZ.) It was sort of a cheap method. I also had him beat Gohan by using the Umisenken and the Yamasenken (which I had upgraded to invisible destruco disks...)
However, barring invented moves and dues ex machina, Ranma will never beat a saiyajin above age 3.

[P.H. Wise]

Could Ranma ever stand up to Dragonball /DBZ ?

Short answer: No.
Long answer: NOOOOOOOoooooooooooooooOOOOOOOOoooooooooooooo.

In the end it comes down to the age-old question...Will power overcome skill?
We look at Ranma and Ryoga. Ranma usually hits Ryoga with many weak punches, whereas Ryoga just hits with one big punch. They're pretty evenly matched that way... Speed and power are a trade-off for both.
Ranma's fast but not as powerful, while Ryoga is powerful, but lacks the speed.
The DBZ characters are so overpowered in comparison to Ranma, that they only need one hit, and contrary to Ryoga they have shown to have retained speed along with power.
The speed Ranma holds over Ryoga therefore doesn't help him anymore, and the punches that the DBZ characters deliver are (if we level it out to Ranma standards (which isn't true, yeah, I know!)) as bad as Ryoga's punches.
