A major one if you mentor under Beerus.They can even fight Golden Frieza on equal footing (Who was strong enough to almost casually overwhelm Goku as a Super Saiyan God Super Saiyan until his stamina dropped) and possibly even SUPER SAIYAN ROSÉ GOKU BLACK!! And that's just before fighting Mira after he absorbs Tokitoki's egg, which has the power of an entire universe's history contained within it, and not to mention that not even the likes of Merged Zamasu will be enough to stop the player character! By that same token the player characters, no matter their race, can stand toe to toe with villains that would give the heroes a run for their money.Considering the power levels of even the strongest human characters in the Dragon Ball lore, this is definitely an incredible achievement. They constantly voice their shock and awe at how a mere human could achieve a power as great as that of Super Saiyan 3, maybe even SSGSS. Players have access to any race from the get-go and can all achieve the same feats as each other, but special mention goes to the human characters for how often NPCs bring it up.Although this also caused Mira to break his power limiter when he finally realized his fighting spirit in inspiration from Bardock, causing the entire final boss fight of the game in the first place. It's enough that Mira has a Villainous BSoD when he's defeated by someone that should be far, far weaker than him. An angered and mentally-freed Bardock fights Mira one-on-one out of raw vengeance, and ascends to Super Saiyan 3 on pure willpower and the power he gained as the Masked Saiyan. The Kamehameha finisher isn't even needed - you kill him in a single strike. Unless you get the alternate ending, in which the fighting souls of close allies wordlessly encourage you and give you their power, like in the first game, before you personally deliver the Dragon Fist and pluck the egg yourself. And for the coup de grace, Goku uses the Dragon Fist to steal the egg out of Mira's body while you finish him off with a ( voice acted!) Kamehameha once and for all.What follows is easily something both more difficult and more satisfying than even Demigra's final form in the previous game. The chips are down, and the final battle against a Super Saiyan 4-esque Mira who absorbed both Towa and the powerful Tokitoki egg has you backed up by Goku in Super Saiyan Blue.It's such a bold move that Beerus is actually impressed, agreeing to sit back and watch for a little while. But unlike Demigra from the last game, Mira isn't afraid of Beerus at all, pretty much telling the God of Destruction to shut up and let him finish his fight. A villainous example: During the Battle of Gods saga, when Mira attacks the player character, Beerus is pissed off because his fight with Goku got interrupted, so he starts threatening Mira.
You unlock all three transformations at the same time. Also an extra level of awesome if you think about it is that Goku and Vegeta had to train for years to get Super Saiyan 1, 2 and in Goku's case 3 independently.What was it Goku said in the Cell Saga? "The power comes in response to a need." To win that fight, both you and your character were in dire need.Your abilities stay locked out to showcase the initial overwhelming anger of the Super Saiyan form, but you won't need them to win.
Then Goku and Vegeta get back up, Goku goes Super Saiyan 3, and the fight is on in earnest.
Especially if you have five full Ki bars and go straight into Super Saiyan 3. Suddenly, it's still a Curb-Stomp Battle, just going the other way. Just when you feel like snapping your controller and walking away as your opponents run roughshod all over you, your abilities are locked out except for one: Super Saiyan. It's easily a Curb-Stomp Battle, up there with the Frieza and Cooler fight in Story Mode in terms of difficulty.
