Goku teaches another character everything he knows.

As far as educational tools goku has a hyperbolic time chamber dealio with the gazeebo of ultimate picnics, rocky maintain-plain generic dbz battleground that goes on literally forever, and a few things like bricks, boulders, weights, cars, targets, etc. He has a maximum of ten years to do it, and morals/character is on, so cap or batman might grate against him personality-wise, and may not get a full education, but any of his students can not kill him as long as he's still teaching them, but when they get out of the time chamber the universe is whatever resulting abomination's playground.

Who would be the most awesome at the end of the course?? :D

Certain powers might speed up the process as well, for example, captain america's near boundless endurance and healing factor would mean that 1: he could use kaioken far beyond his body's normal capacity to use kaiyoken, because any damage it deals him is almost immediately repaired, and 2: well, he wouldn't have to take as many breaks between lessons, or just as much time resting at all, and so he would complete his training much faster.

And another note, this is not a versus thread, this is supposed to be a lighthearted (and I hope fun) little "what if", and as a general guideline, it's not exactly about who would be most awesome by the end, it's who would benefit from the training the most. For example, by the end galactus would still be galactus but with a few more tricks up his continent-sized sleeve and the ability to become independent of planets for energy, and just eat a spirit bomb every once in a while. But wolverine would suddenly be on par with some of the heaviest hitters in mainstream marvel, due to the mass and durability of his adamantium bones, his immense healing factor, and the fact that his claws are natural extensions of his body (and he could therefore coat them in a ki aura to make them even sharper than they already are, a power illustrated when trunks channeled ki into his otherwise normal blade to cut a planet buster in half, and that goku used to block said blade with his index finger).

... Too lazy to read all of this.

I'd love to see AMAZO with his combination of Superheroes' powers. Also I think Captain Marvel/Shazam/whatever his name is now is a child and more lighthearted so would probably be able bond with him and he has some mastery of magic already

Imagine Amazo being able to go anywhere in an instant with Instant transmission and having energy projection that can easily blow up planets lol

Imagine Hulk being able to fly as fast as his energy reserves allow(which is huge) and having a huge boost in combat speed due to the training. Hulk with the Kaioken technique would be hilariously overpowered. That'd be scary

Hulk with instant transmission = GG

Hulk with ki amped fists = GG

Superboy...end of thread

@unbreakable_fs4: Op here, and Jesus that would be terrifying, hulk could do SO much with kaioken. Like, using it tears up your muscles and can become really painful, but pain only makes hulk angrier, and thus tougher, and thus able to use higher levels of kaioken without being outright destroyed, and thus be in more pain, and loop for almost infinite strength and speed. Honestly, hulk + kaioken has the potential to take on some of the bigger threats in DBZ!

Now, another thing, what would happen if the resulting characters where let back into their own respective universes?

Broly and Buu ain't got nothing on that!

@changeordie: If someone like Hulk had all these new advantages, he'd be higher tier than he already is. Even though he's grown exponentially in power and improved significantly in speed, there are still many people who could still make short work of him

@unbreakable_fs4: Yeah, and plus, I theorize he could probably only pull off a kaioken x6 when perfectly calm, and after that the scaling would be slow. The thing I like about this idea is that he can manually power up, instead of having to fight someone and get angrier that way. He could literally sit on a hill and kaioken all day until he has enough strength to one-shot planets, speed to make quicksilver look like he's standing still, and power to vapourise a helicarrier with a thunderclap. But still, now, what would happen if this hulk was let back onto marvel earth?

Oh, also, wolverine would kick all kinds of ass if he had goku as a mentor. Not only is he already a master martial artist, his healing factor would mean he could ignore the side effects of kaioken, so that he could annihilate opponents with a single adamantium-fist superpunch. He would probably be able to hang with the more powerful avengers like thor. Also, has anyone ever considered how much it would friggin hurt to be punched by wolverine? He has peak human strength, bruce-lee level H2H combat skill, and his fists are laced with the strongest metal in the world, it would be like being kicked by a shod horse. o-0

Superman with the kaioken ?....
