Goku became a Super Saiyan during the Saiyan Saga?

[Ultimate Cell]

So let's say that Goku became so pissed and angry that Nappa killed off his friends that he manages to get so mad that he becomes a Super Saiyan like when Freiza killed :Krillin . How would this effect things?

Nappa would be instantly killed without mercy, whilst Vegeta would be KO'd with a simple kiai, though Galu would most likely still have the self control not to kill him. When Vegeta awakens, Goku gives him one chance to leave the planet or die, with Vegeta likely realising Goku is a Super Saiyan and requesting they form an alliance, informing him about Freeza. The group then head to Namek with Vegeta, though still don't make much of a direct confrontation due to Vegeta still being concerned about how strong Freeza may be. They would strike out during the attack on Dende's village, except not only would most of the characters be far stronger due to training with Goku, but Vegeta and Goku would likely wait until Dodoria started chasing the other two for Vegeta to launch a pincer attack against Dodoria and SSJ Goku to wipe out all the men around Freeza whilst stealing the DBs Zarbon held before getting his friends to safety.
With Freeza having no scouters, the main cast have far more freedom to move in this version, finding and saving what villagers remain whilst gaining the Dragon Ball Vegeta would've otherwise taken and all heading to Saichoro's house, getting their potential unlocked shortly after. The Ginyus arrive a lot sooner than in the main timeline, but the potential unlock would likely be a substitute for the Gravity training and make Goku as strong as his canon self but with SSJ. With this, and Vegeta being stronger than his canon self, the Ginyus are easily killed by the two other than Ginyu, who'd be guarding the ship and would only realise his men had been wiped out once the Z-Warriors arrive. The fight between he and Goku is relatively the same, just without Jheese's distraction, and the events with the Body Change cause it to be a quicker version of what happened in the main timeline. The only difference is that the newer model healing chamber wasn't damaged by Vegeta, so Goku is able to heal a lot faster than in the main timeline, likely healing by the time they made their wishes in the main timeline. They still have to wait for Dende to get back, so what ample time they have isn't worth much. The main difference is that Saichoro's grief would be less due to the village that had been saved and Goku would arrive to stop Vegeta pressuring the group to grant his wish. As such, Goku is confident to face Freeza when he arrives and wishes everyone but he, Vegeta and Freeza back to Earth. Goku lets Freeza go into his true form and 100%, with the battle being the same as in the main timeline other than that the planet isn't at risk. Goku eventually defeats Freeza after 3-4 minutes troll), though with Vegeta there no opportunity would be left for Freeza to survive. As there would be no need not to oblierate the two scouts in this version, Kami's ship would still be undamaged as would Freeza's, so whichever one the two find best to escape on together is used. They likely remain in space for a while to train, with Vegeta's hateful facade lessening at a quicker rate as in the main timeline and him possibly gaining SSJ from Goku's training. They'd head back to Earth once Goku senses Cold heading for it, thus arriving a lot sooner than in either of the other timelines. Trunks' timeline remains fairly unchanged, whilst for the timeline where the Cell Arc happens, the lack of Shunkan Ido means everyone gets killed by Cell's explosion.

-Nappa is beaten much easier
-Vegeta is beaten fast because Goku would have a much larger head over him
-Goku would go to Namek with Krillin, Gohan, and Bulma
-Goku would only receive some image training, not increasing his power a lot
-Easily deals with anyone on Namek that comes their way, save Frieza
-Gets his potential unlocked from Guru, increasing his power quite a bit
-Solos the Ginyu Force with ease
-Loses to Frieza, no way around defeating him really

This, I don't see anyway for Goku to surpass Freeza since he can't abuse more Zenkais which helped him a lot to overcame the gap between him and Freeza.

Considering how the potential unlock ended up bringing Kuririn/Gohan's battle power into the hundred thousands by the time they confronted Freeza, I can see someone who started off over five times stronger than them easily getting into the millions from the unlocking. Factor in the training and what Zenkais he may receive due to still having Senzu at hand and he'd probably reach his canon power so long as he doesn't rush to Freeza immediately.

As soon as Goku transforms, Vegeta realizes he is the legend and talks to him about Freeza. Considering not even Freeza's 1st form's power is known and Vegeta is deluded by the SSJ legend, he is sure that Goku can win. The fact that Goku does not fight Nappa/Vegeta in this timeline along with his new form making him feel superior to anyone by a wide margin render him indifferent to trying 100x gravity training. Since Krillin and Gohan are not needed under those conditions, Goku follows the two Saiyans himself. When they arrive, they attack Freeza right away and they all get killed. Freeza keeps ruling while Androids ravage Earth.
