Goku's powers are on a much higher scale. His ability to destroy planets as a Super Saiyan makes him far more powerful than Naruto at his strongest. Naruto's jutsu are mainly focused on the ninja world, while Goku's powers are universal.
In fanfiction, Naruto's shadow clone jutsu could be combined with Goku's Instant Transmission. For example, Naruto creates multiple clones and they all use Instant Transmission simultaneously to surround an enemy. This would be a very effective strategy.
Goku's powers are on a completely different level compared to most characters in Highschool DxD. His Saiyan abilities like Super Saiyan transformations give him incredible strength, speed, and energy projection. In contrast, the characters in Highschool DxD mainly rely on magic and their devil or angelic powers which, while powerful, are not on the same scale as Goku's in terms of raw power. For example, Goku could easily defeat most low - level devils with a single punch in his base form.
Well, Goku's Saiyan powers are all about brute strength, speed, and the ability to transform into more powerful forms. Android 21 has her unique android abilities like energy absorption and regeneration. If they combined their powers, they could create some really powerful attacks. For example, Goku could charge up a Kamehameha while Android 21 absorbs energy from the surrounding environment to make the attack even stronger. Their combined speed would also make them a formidable duo in battle.
In a Naruto - Goku fusion, there could be a new form of energy manipulation. Goku manipulates ki, and Naruto uses chakra. They might create a hybrid energy that has the best of both worlds. This energy could be used for long - range attacks like Goku's energy blasts and also for close - combat like Naruto's Rasengan. Also, the fusion could have enhanced senses, borrowing from Goku's Saiyan senses and Naruto's ninja training.
Goku's power level is extremely high compared to most Young Justice characters. His Super Saiyan forms would likely outclass the strength of many of them. For example, his Super Saiyan 3 form could probably take on a large group of the Young Justice villains single - handedly.
Goku's ki - based powers could be seen as a parallel to the magic in Fairy Tail. His attacks like the Dragon Fist could be considered similar to some of the dragon - slayer magic in the series. When he uses his ki blasts, the mages in Fairy Tail might initially mistake it for a very powerful and unknown type of magic. Goku could also learn to sense ki in a way that helps him detect magic users and their power levels more easily.
Goku's powers would be a shock to the Naruto world. His super strength that can break mountains and his speed that is faster than the eye can see would make the ninjas reevaluate their own power levels. His powers would likely be the subject of much discussion among the ninja clans. Some might try to find ways to replicate his powers using chakra, while others would simply be content to have him on their side in battles against common enemies.
Goku's powers are on a completely different level. His Super Saiyan forms would make him extremely powerful compared to most Naruto characters. His ability to fly and shoot energy blasts would be like nothing they've ever seen. Even Naruto in his strongest forms might struggle against Goku.
If Goku time travels, his powers could change in several ways. For example, if he travels to a time when the power levels were generally lower, like the early days of the Saiyans, his current power might seem overwhelming. He could easily defeat foes that were once considered strong. However, if he travels to a future where new threats have emerged, his powers might be relatively weaker compared to the local powerhouses. He would then have to train harder and adapt to the new power scale.
