The early parts of the saga stay the same, the only difference is that instead of choosing Buu Goku chooses Citron who says his goodbyes to his Namekian people before leaving, the first fights like Goku vs Botama and Frost stay the same until it’s Citron vs Magetta, at the start of the fight Citron uses his Namekoid form to dodge Magetta’s lava spit, and due to Citron having the increased focus(thanks to Namekoid) he figures Magetta’s weakness out pretty easily and defeats him leading up to Citron vs Cabba(CVC), Citron easily pushes Cabba while using basic Super Saiyan, seeing this other universe Saiyan struggling Citron starts telling him the need to achieve Super Saiyan, Citron pulls from his own experience of grief and starts telling Cabba to start imagining thing’s that anger him pr make him sad allowing Cabba to achieve Super Saiyan As to show how far Saiyan’s can go Citron once again shows Super Oozaru Saiyan, the power jump from the simple yellow hair Super Saiyan to the red fur of Super Oozaru Saiyan is so shocking towards Champa, Vados and Cabba. Citron does eventually push Cabba out of the ring leaving new knowledge for the Universe 6 Saiyan. The next opponent for Citron is Hit, after knowing Hit’s Time Skip is a big threat Citron powers up to Super Oozaru Saiyan 2 allowing Citron to tank the invisible strikes, Citron tries to use his Namekian trained focus to predict Hit’s movement during frozen time, but due to Hit continuously adapting increases his time skip, and after a high speed struggle Citron ends up losing leading to Goku vs Hit, and thanks to Citron, Goku knows how Hit fights, leading to Goku revealing SSJB and the arc ends the same. continue reading in Notes/Credits
The saga opens 17 years in the future. The peace Future Trunks fought so hard to achieve is utterly shattered by two mysterious, sadistic entities known only as Goku Black, and Citron Black. Both dressed in dark robes and wearing a single green Potara earring, both tyrant’s possess Goku and Citron’s face and voice but harbors a pathological hatred for mortals, calling their mission the "Project Zero Mortals.". like normal Trunks appears in the past again but much more beaten, and he gets back to full health wakes up and attacks Goku like normal before realising this isn’t Black, so he asks to see Citron. They arrive on Namek and are greeted by the Namekian’s as well as Citron who is happy to see his allies again, they catch him up on the problem so Citron agrees that it’s pretty bad, Goku Black appears on Earth and not seeing anyone there goes to Namek meeting the group there, the normal Goku v Goku happens like normal with GB being dragged back to the future. Beerus sees all the connections to the Kai Zamasu like normal, they go to him Goku spar’s and defeats him starting up his obsession unintentionally, it reveals the plan, Zamasu kills Gowasu, steals the Time Ring and watches the fight between Citron against Hit to Goku against Hit, it’s disgusting. For one of the three manage to reach level’s of a god with nothing divine like, for two of the three people has divine ki which no mortal should have. It was an embarrassment to someone like Zamasu, so he went with the strongest one of the time, Citron, who while only a little stronger than Goku still counts, but it would be nice so he goes to Future Trunk’s timeline befriends that timeline’s Zamasu and have him become Goku Black. So, in a way to prevent this nightmare Beerus erases present Zamasu, only it doesn’t work as when Citron, Goku and Trunk’s head to the future both Citron Black and Goku Black are there, both Black’s decided to reveal their unique forms, Goku Black: Super Saiyan Rosa. Citron Black: Super Oozaru Rosa. Both reveal how they achieved where they are, not only that but GB reveals he brutally murdered Goku’s family, while Citron revealed he murdered all the Namekian’s and blew Namek up. This causes Goku to rage in Blue, even with his better self-control Citron rages in Sos2(Super Oozaru Saiyan 2), though the Black’s do end up proving too much, causing the team to retreat and re-plan, allowing the Black’s to recover themselves and get stronger. Even with their strength’s both Citron and Goku will push the Black’s to their limit and not wanting a risk they activate their potara fusing into Citku Black and ultimate fusion of absolute power calling himself justice given form, while Goku would recommend it Citron refuses even with Goku trying to convince him Citron wants to singerly get revenge for his Namekian families so he powers up to Sos2 once again and charges, though Citku Black seems to strong meaning Goku steps in with Trunks but even then it seems in Citku’s favour. Knowing Citron is the stronger of the three Saiyan’s Goku tells Trunks to give Citron their energy, feeling his energy rising Citron starts charging up. Citron’s silver aura turns diamond blue and grows in size as he explodes in power now in Super Oozaru Saiyan 2 Ultimate, this allows Citron to get the upper hand on Citku Black, the fight reaches it’s pinnacle as Citku starts charging a Ugoku Kamehameha, Citron think’s outside the box and starts charging a Sub-Bakudan(similar charging up as a normal Ugoku Bakudan and explosive/destruction potence when fired but not requiring as much energy as the normal one and is one handed), Citku Black and Citron enter a beam clash but Citron’s Sub-Bakudan manages to split its way through Citku Black’s Ugoku Kamehameha and right through Citku’s chest killing the threat.
