By now, you probably know that Son Goku is one of the most powerful and potent fictional characters ever created. He is not the most powerful one, but he is at the very top. On the other hand, Rimuru Tempest from the That Time I Got Reincarnated as a Slime is basically a deity as well, which means that Rimuru is quite powerful. This situation prompted us to think about whether Rimiru could defeat the protagonist of Dragon Ball, which is what we are going to talk about in this article.
Although Rimuru is a deity in the world of That Time I Got Reincarnated as a Slime, Son Goku would easily win this fight. Namely, the world Rimuru comes from is much less dangerous than Goku’s multiverse and Goku has more powers, as well as more experience, which would definitely help him win this fight.
Now that you have the short version of the answer, the rest of the article is going to be divided into three sections, with the first two introducing the characters, their powers, and their abilities. In the end, we’re going to give our final verdict and explanation on why Son Goku would ultimately be able to defeat Rimuru Tempest in a direct fight.
Rimuru’s powers and abilities
Rimuru Tempest, formerly known as Mikami Satoru, is the main protagonist of That Time I Got Reincarnated as a Slime, as well as the founder and king of the “Great Jura Forest” monster country. Tempest and is considered to be one of the most powerful Demon Lords among the Eight Star Demon Lords, as well as the only currently known Great Demon Lord. He is also a partner and best friend of the “True Dragon” Veldora Tempest.
Using the Great Sage, you can quickly read a book by copying it completely. Simultaneous utilization of Great Sage and King Beelzebub’s Gluttony allows high-speed copying and revision of the magic books he holds in his hands. With that, you can postpone checking the content of the book for a later time. Unfortunately, it is not possible to be able to use magic simply by copying the books.
But, by taking it and copying it, he can index the magic books he wants. After this, it is necessary for you to study them one by one. Taking this into account, it can be said that Rimuru possesses a great deal of knowledge about magic, as well as being speculated to be able to use most of the magic in those books.
After evolving into a Demon Slime, he gained the ability to freely switch between material and spiritual bodies. As a result of his evolution, his total magical energy greatly increased. Compared to the original amount, he was ten times larger. He can use abilities that don’t rely on magical energy, such as augmenting his abilities using the Herculean Strength fighting spirit technique.
Thanks to Hakurou’s guidance, his sword skills improved. He was able to analyze the summoning magic that he first saw during the adventurer exam and gained the ability to use it. After fighting the Guardian of the Labyrinth, Rimuru has the ability to create golems. The Golem’s abilities can be added through the possession of a spirit or a demon.
The outer appearance of the golem is created according to his imagination. Rimuru can copy space manipulation techniques just by seeing it, such as when he copied the Unique Ability Restrictor that belonged to Gozurl. In this form, Rimuru can also pretty much copy any other Skill or Magic as long as he has seen it. After naming an Ultimate Ability, Lord Raphael’s Wisdom, as Ciel he acquires an ego, that is, a soul, and evolves into a Manas, an intelligent being born from an Ultimate Ability.
After the fight with Yuuki, Rimuru gained the ability to use Instant Move which allows him to travel through Space-Time at will. Using this ability, Rimuru was able to travel to his old world where he saved his own self, Mikami Satoru, from death. He was also able to return from the place beyond time where he was exiled by Yuuki.
The ability described is the ability to reach the desired point instantaneously through space and time. At the end of the web novel it is hinted that Rimuru is perhaps a reincarnation of Veldanava the creator God of existence itself.
It is not very well understood since it may be that he is a reincarnation or just the successor of this since Veldanava, like Rimuru, wanted to create something that would maintain balance and endure peace between the species. It may be that Veldanava allowed him to be his successor since when Rimuru was going to say his name, his real name, the author censors that part implying that he is someone who has exceeded any limit of existence resembling a God in this case Veldanava.
Also at the end of the novel Rimuru exists in his original world and in the current one in a parallel way thanks to his Parallel Existence ability. It is also implied that the Rimuru in this case Mikami Satoru of the original world keeps the memories of him only up to the point that he was revived and from then on he has to continue without knowing anything about the other world.
Son Goku and his powers
Son Goku is the main protagonist of the manga Dragon Ball and Dragon Ball Super, and their animated adaptations, Dragon Ball and Dragon Ball Z / Dragon Ball Kai, then Dragon Ball Super, as well as the alternate animated sequel to the first two series, Dragon Ball GT.
Growing up, Goku becomes the strongest warrior on Earth and faces numerous increasingly powerful adversaries who threaten the peace of the planet and the universe. Goku transforms into Super Saiyan for the first time when Frieza kills Krillin on planet Namek. As the series progresses, Goku reaches other levels of Super Saiyan, which, depending on the stage, make him change his appearance and increase his fighting strength.
The following stages reached by Goku after the first level are, in order: the second, the third, and the fourth stage of the Super Saiyan, the Super Saiyan II, and the Super Saiyan III. Goku also reaches an intermediate state between the normal Saiyan and the Super Saiyan I, called False Super Saiyan.
In the 195th episode of Dragon Ball Z, Goku confronts the members of the Ginyu Squad in hell. On this occasion, Goku’s hair appears raised as in the Super Saiyan stage but black, and the aura appears golden: it is not the False Super Saiyan (which is devoid of pupils and irises) but the consequence of a late script change (initially it was expected that Goku would face the Ginyu Team transformed into Super Saiyan, then it was decided to keep this form for the clash between the Saiyan and Paikuhan in the four galaxy tournament), which prompted the designers to limit themselves to recoloring Goku’s hair rather than redrawing the scene.
In Dragon Ball GT, Goku reaches the stage of the Golden Giant Monkey (the equivalent of a Super Saiyan in the form of a Giant Monkey) and Super Saiyan IV. In Dragon Ball Super, thanks to the energy of five other Saiyans, Goku reaches the level of the Super Saiyan God, which he later internalizes and manages to reach without the help of his companions.
In the movie Dragon Ball Z – The resurrection of ‘F,’ and also in Dragon Ball Super, after training with Whis, Goku reaches the stage of a Saiyan beyond a god, obtained by maintaining the power of the Super Saiyan God in the basic stage. Still, in the same film and in Super, he reaches another stage, the Super Saiyan God Super Saiyan or simply “Super Saiyan Blue.”
In the Dragon Ball Super anime, he manages to combine the devastating power of the Kaiohken with the transformation of the blue Super Saiyan, giving rise to the blue Super Saiyan Kaiohken, in order to face Hit. In the Dragon Ball Super manga, Goku also manages to reach the final blue Super Saiyan stage in order to face molten Zamasu.
During the Tournament of Power, Goku manages to obtain Ultra Instinct, a particular condition that makes the body capable of reacting and adapting autonomously to threats, thus eliminating reaction times. The acquisition of Ultra Instinct provides Goku with two new transformations. The first, called incomplete Ultra Instinct, is the consequence of a raw and incomplete use of Ultra Instinct.
Goku’s irises turn gray, his body gives off a silver aura, and his hair sways upward. In addition to this, Goku’s gaze becomes more severe, and his voice deeper and more aggressive. The second, called Complete Ultra Instinct, is acquired by Goku as a result of the experience acquired using Ultra Instinct in the previous state. In this form, both irises and hair become silver in color.
Also, in this case, in the manga, the build corresponds to that of the Super Saiyan God. In this form, Goku’s power grows with anger, and in addition to enabling him to powerfully overcome the might of a God of destruction, it makes him virtually the most powerful mortal in the Seventh Universe.
Rimuru Tempest vs. Son Goku: Who would win?
Comparing characters with Goku is usually a useless task because he actually beats almost anyone. Rimuru Tempest might be the strongest character in the universe of That Time I Got Reincarnated as a Slime, but that universe is significantly weaker than Goku’s universe and, thus, comparatively, Goku’s weaker forms are basically on the level of the strongest characters of That Time I Got Reincarnated as a Slime.
Son Goku has fought aliens, monsters, martial artists, and even deities in his own universe, all of whom are significantly stronger than anything the world of That Time I Got Reincarnated as a Slime has to offer. In that aspect, we can only confirm that Goku would beat Rimuru and that he wouldn’t even have to give it his all.
Goku is a better fighter, he is much more experienced than Rimuru and he has powers and abilities that Rimuru simply cannot match. This is why Son Goku wins this one.
