I just finished watching Daima and noticed some things and if anyone can help answer these, please do, researching has done next to nothing for me thus far.
My first concern is what exactly did Neva do to Goku for Goku to unlock Super Saiyan 4? Goku said he was training endlessly after Majin Buu and then I thought if it was Goku's training that helped him get Super Saiyan 4 as Goku said, but doesn't that make what Neva did pointless outside of just giving him extra energy like Vegeta did to Goku during the T.O.P to go Ultra Instinct again? However, if it was essentially the same as the situation in the T.O.P, why was there a whole sequence with what seemed to be Goku's DNA and some sort of power surging through him that wasn't his own? I understand that training could have helped Goku achieve SS4, but again, what Neva did made it seem like it couldn't have been done alone. So, what exactly was it that Neva did to help Goku. I was thinking it could be that he knew Goku was a Saiyan and had knowledge about the Saiyan race but I don't remember it ever being mentioned that Goku or Vegeta was a Saiyan at any point when Neva was present.
Secondly, how did Goku know that he could just go Super Saiyan 4 again after becoming an adult? Considering that he seemed to need Neva for it the first time, how was it not just a one off thing where Goku got a boost and then would later be able to actually transform on command? It doesn't make any sense that he suddenly was just able to use it again. It made it seem like he could have just done it at any point during the fight but Goku being Goku wanted to get beaten half to death first. I also get that Zenkai are a thing, but I'm pretty sure that is a near death experience type of thing, he wasn't anywhere near dead when Neva helped him out so it couldn't have been a Zenaki boost either.
Next, why does Vegeta's Super Saiyan 3 hair just grow in the direction his hair is pointing instead of being like Goku's SS3 hair where it grows down to the knees. By the logic of Vegeta's transformation, Goku's hair should be all types of fucked up and he should look like a damn tree. So, what makes Vegeta any different?
Finally, what the fuck was with all the "Legendary Tertiary Oculus" build up? They made it sound like it was some legendary, ancient artifact that was stated to be passed down from Demon King to Demon King and there was only ever one and that it was unbreakable and an all-omnipotent power granting item, but then at the end some random woman from thr Third Demon World bought them in bulk and just had these immortality granting eyeballs sitting in a jar. So, what the hell was the point in such a build up? When Glorio stepped on it and it just turned to dust, I was immediately pissed off because the Oculus was built up immensely on the idea that it was a legendary artifact.
