If Piccolo beat Frieza...

[Origibros]

If Piccolo beat Frieza what could happen next? Would he of killed Vegeta too or do you think he would let him live? How would the future pan out?

[FoolsGil]

I suppose it would be based on Gohan's and Krillin's objections. Though at the level Vegeta was, he wasn't a threat, Piccolo perhaps would have spared them on that alone.

King Cold would likely travel to Earth on his own and get killed by Trunks. If Piccolo killed Freeza then Goku would learn how to go SSj and learn how to use the Shunkan Ido. I think Cell might be a bit weaker since he won't have Freeza cells, but everyone still end up being killed later on.

Cell would still have Freeza's cells since he would be coming from another timeline, where presumably things still played out like canon.

Also Cold wouldn't know about Earth since it was Freeza who told him about it.

Was Piccolo strong enough to stop 19 and 20? If so then at least they'd survive until 17 and 18. Maybe they would find SSJ1 in the time chamber.

[Hellspawn28]

I totally forgot that Freeza told Cold about Earth. Either Cold never bother going to Earth or he finds out that Freeza was beaten by a group of people from Earth.

Assuming that Piccolo does let Vegeta live, and that Vegeta stays on Earth and would hook up with Bulma. How would they have defeated Cold in the original timeline if Goku never became a SS (I'm assuming you meant Goku wouldn't learn SS and Shunkan Ido). Wasn't Cold supposed to be around Freeza's power or at least strong enough for Freeza to think he could help against Goku?
I guess its possible that Goku could be/become strong enough to beat Cold using just KK or gain SS while fighting him but if that was the case then why would Trunks have jumped in to fight Cold if Goku was on Earth when he showed up? He only jumped in against Freeza and Cold because for whatever reason Bulma never told him that Goku had Shunkan Ido so he thought that he wouldn't make it in time.

Actually, if Piccolo was somehow strong enough to beat Frieza, then logically, he should be able to take care of anyone else since he's APPARENTLY so absurdly strong, right?

If he beat final form full power Freeza then sure. I was assuming the OP meant some how beating Freeza in his second form by not letting him transform.

[Hellspawn28]

King Cold is stated to be weaker then Freeza. I would imagine Piccolo could beat him in the original timeline.

[Low Tone G]

I think they would definitely killed by Androids, or only Goku, if their aim was to kill him. Or if they would have spare them, just like in canon, then Piccolo would have had his fusion with Kami, but later would be killed by Semi-perfect Cell or something like that. Even if they could attain SSJ while fighting that androids, and somehow entered in ROSAT, it wouldn't be enough, neither for Gohan, as Goku wasn't able to figure out how to master SSJ1, beacause he wouldn't have known how to if he wasn't enough experienced being a SSJ.

[Cipher]

Oh, you want to change one thing in Dragon Ball?

Everyone dies.

[Hellspawn28]

If the Cell games does happen then Cell would still blew up the Earth since Goku would never travel to Planet Yardrat. Cell could travel to Namek and blew up the Planet to avoid them wishing everyone back.

No. Cell wouldn't know jackshit about Namek. He couldn't travel there even if he did know because he doesn't know IT and he doesn't know any of the energies there even if he did.
This is what would happen.
Piccolo would beat Freeza, he said that he'd handle Vegeta afterwards. There's a slight chance that he wouldn't, but Piccolo isn't forgiving like Goku. Vegeta dies, no Trunks. King Cold would not travel to earth because Freeza wouldn't have been able to tell him about earth. Everyone travels home safely and are killed by the Androids 3 years later. If they aren't killed by the Androids, then someone would come back from the future. If anyone came to the past to give Goku his antidote, it would be Bulma. Goku would learn of the androids and train with Piccolo along with Tenshinhan, Yamcha, Kuririn and Gohan. Everyone would be the same strength in base form as the original series. Android #19 massacres until Goku pulls out a 20-fold Kaioken. Defeats him. Piccolo then shows his ability to increase his power and defeats Android #20. They defeat the Androids when Kami tells them that there's something else. They attempt to confront Cell and are told that they wouldn't stand a chance. Piccolo fuses with Kami and defeats Imperfect Cell. They still need a guardian to wish back the people Killed by the Androids and Cell, so they travel to Namek. Piccolo stays to guard the earth while Goku, Gohan, and Krillin take another trip to Namek. They find More PTO soldiers there and see King Cold is there and he discovers the Dragonballs. They fight against Cold and this is where Goku disovers the secret of the Super Saiyan and defeats Kind Cold. End of series. Babidi possibly comes to earth but sees that nobody is able to supply energy for Buu and he leaves, never to be seen again. Somewhere in the middle Bulma has a child with Yamcha named Trunks maybe?

EDIT: This isn't exactly what would happen just a hypothetical.

[Gokuden]

I'm pretty sure Rosat is key here. I would say that Trunks wouldn't have a welcome party, and would be greeted by the Cold family. Then would look for Goku, who is now ChiChi's course boy while a little training with Gohen, then Trunks would probably kill him by mistake when they fight with the sword, or accuse him of not being Goku since he cannot transform. I'm pretty sure... By this time Vegeta would probably be nearing SSJ levels. Maybe Trunks would never be conceived, but Future Trunks wouldn't disappear, because he may or may not come from a different timeline.

From there the androids could be weaker, or more powerful than Future Trunks' timeline. Everyone has trained, and Vegeta and Goku started sparring with Trunks, and reach SSJ levels. But Trunks also benefits from Goku's guidance, and Vegeta's hard love. The trio reach the level of Super Saiyan Trunks minus the sword, but Trunks somehow gets stronger.

Kid Gohan dies because of some unknown disease, and Goku comes out unscathed.

Trunks becomes a false prophet, and is forced to flee, this is probably how AT Trunks gets to SSJ3 lol.

Cell appears before Android 18, and Android 17; depending on their strength, they either decimate him and wait for bibabo to come unleash his carnage against the Z fighters, or perfect cell gobbles them up until he is super ultra terrific perfect.

Either way, everyone dies.

Not knowing about boo, and failing to reach their usual levels, they deaded hard.

Goku would be greeted by a SSJ trunks, who would probably tell him ''you're not Goku! You can't even go SSJ!)

[Low Tone G]

My point is that Future Trunks would not born, and if Piccolo would be the hero to beat Frieza, that they most likely could defeat Cold, but failed to sop the androids, so Piccolo would have his fusion with Kami and defeats the androids somehow. Cell would not appear in the Android saga as he was an infant in that time. But on all of cases they will be killed by Dabra in Majin Buu saga. Or if somehow Gohan could reach SSJ2 and adult for the first time, then they could defeat Dabra, and everyone get free because there is not enough energy for Majin Buu to come back.

[RocktheDragon]

Even if Piccolo would have beaten Freeza I still think Goku and Vegeta would have reached the ability to transform into SSJ's. It wouldn't have happened the way it did in battle with Freeza but they would have found their bearings eventually, it would just be a matter of time and training.
