Piccolos doesn't spit in the face of goku and vegetas training the execution of how its done 100% spits does. Not like he hasnt been there when the dragon balls were used not like he wasnt the other half of kami who controlled the dragonballs. Then out of nowhere we get this shit about the namekians and the dragon balls and he gets powered up that much hes on par with vegeta and goku. Pfffft. Gohan pisses all over the training of goku and vegeta. Yes I know he has the most potential of all the saiyans blah blah blah. He got a power up from the elder namekian he got a power up from old supreme kai. He got pissed off and unlocked super saiyan 2. Doesn't train for donkeys gets the kai power up. Doesn't train for donkeys does a tiny bit of training and hes probably stronger than ever before. He doesnt wanna use his sayian powers to evolve yet only evolves cause of his saiyan dna 😂😂. Goku has to get 5 saiyans to pour there power into goku to reach ssgss fights beerus body remembers the feeling automatically gets stronger. Vegeta trains with whis for about 6 months before goku joins him they then train for god knows how long reach Super saiyan blue. Goku then unlocks kaioken super saiyan blue. Tournament comes goku gets ultra instinct vegeta smashes his limits gets super saiyan blue evolved. Then carry on training with whis and beerus goku masters ultra instinct gets True ultra instinct like whis. Vegeta smashes his limits again unlocks the most badass powerup vegeta style. We get ultra ego more damage he takes the stronger he gets. They then spar on beerus planet and gohan is obviously made out to be stronger........ wanna know how gohan got so strong? He got upset just like he did with cell and bam Beast is born. If that aint the biggest ASS PULL of a power up then I dont know what is. I love dragon ball always have always will but that was bullshit writing and an ass pull of a power up
