He has a carefree personality. After becoming a king and experiencing the reality of the death of his close friend Shion, his naïve nature decreased. Unlike most other shounen protagonists, he has no problem with decimating any forces who dare to harm his subordinates and his country, regardless of their numbers. As he progresses through the story, he slowly becomes more and more like a True Fallen King.
Rimuru also tends to "overreact" when there's danger to his close ones, such as his countrymen, subordinates, friends and students.
Rimuru initially appears as a pure white-bodied slime, but upon becoming a Demon Slime, his body turns silver with streaks of gold. His mass has grown over time, allowing him to accommodate larger human forms. Towards the beginning of the story, he only has enough mass to appear as a child, but by the time he becomes an Ultimate Slime, he has enough mass to appear as a 16 year-old.
In this form, Rimuru possesses silver hair. There are no visible sex characteristics; however, he is often mistaken for a young girl. This is likely due to the fact that the original form belonged to Shizue Izawa.
Since his slime body is equal in mass to his human form, he fills this body with solid shape instead of black fog. Without the black fog, there is no additional magic consumption required to maintain the form. There is no discomfort when he assumes this form. If he uses the black fog, he can also assume the form of an adult.
His fine motor capabilities improve when he is in his human form, and he finds it easier to move in than his slime form. Even though it appears to be human, this form has no need for breathing, excretion, and reproductive organs. However, he can freely eat, taste, and drink.
In his human form, he wears a black fur coat and a scarf. Under the coat, he wears the kimono and pants that Shuna had made for him. He also wears the steel thread underwear he makes himself. He often wears Shizu's old mask to hide his demonic powers.
Since eating the Orc Disaster, his human form grew a bit. He now assumes the form of a pre-teen with feminine features. In this form, he is around 150 cm in height. In addition, he has obtained a devil transformation.
Upon becoming a True Demon Lord and changing his race change to Demon Slime, Rimuru has been depicted wearing a black overcoat. His nails also appear sharper and his overall human form appears slightly older.
Upon evolving further into an Ultimate Slime, Rimuru's human form ages to 16-17 years old. This form is described by Velgurind as appearing gender-less (as she saw it nude upon creation) but with dangerously cute features. By simply willing it, Rimuru can generate clothes from his own mass and magic power.
Using Great Sage, he can quickly read a book by copying it completely. Simultaneous utilization of Great Sage and Gluttony allow the high speed copy and review of the magic books that he holds in his hands. With that, he can postpone checking the content of the book for a later time. Unfortunately, it is not possible to be able to use magic just by copying the books. But, taking and copying it, he’s able to make the index of the magic books that he wants. After this, it’s necessary for him to study them one by one. Taking that into consideration, it can be said that Rimuru holds a great amount of knowledge regarding magic as well as being speculated to be able to use most of the magic in those books, if not all of them.
After evolving into a Demon Slime, the ability to freely change between material and spiritual bodies was added. As the result of the evolution, his total magical energy greatly increased. Compared to the original amount, it was ten times as large.
He can use skills that don’t rely on magical energy such as raising his abilities using fighting spirit technique with Herculean Strength in addition.
Thanks to Hakurou’s guidance, his skills with the sword was improved.
He was able to analyze the Summoning Magic he first saw during the adventurer exam and acquired the skill to use them.
After fighting the Guardian of the Labyrinth, Rimuru has the ability to create golems. The abilities of the Golem can be added through the possession a spirit or a demon as Rimuru made them inhabit the Golem. The outward appearance of the golem is created according to his imagination.
Using Manas: Ciel, Rimuru can copy space manipulation techniques simply by seeing it, such as when he copied the Unique Skill Restrainer which belonged to Gozurl. Like this, Rimuru can also copy practically any other Skill or Magic as long as he has seem it.
After the fight with Yuuki, Rimuru gained the ability to use [[[Traveler|Instantaneous Movement]]] which lets him travel across Space-Time at will. Using this ability, Rimuru was able to travel to his old world where he saved his past self Mikami Satoru from death. He was also able to return from the place beyond time where he was exiled to by Yuuki. The ability as described is the ability to reach the desired point instantly across space and time.

●Anti-demon Mask: A magic mask left by Shizue Izawa. As it's name implies, it suppress demonic power. It also serves as a treasured memento of Shizue, as it is the only remaining possession of Shizue which Rimuru possesses.
●Dark Leather Guards: He received dark leather guards from Garm.
●Kimono: It is made of glossy linen - first-class silk that feels wonderful to the touch. Putting the silk to his body, it immediately changes size to fit him. After mixing with his magic, it became as if a part of his body. Even in his adult form, the clothing grows appropriately. This clothing absorbs the aura of its wearer, and can change its appearance. Rimuru’s clothing turned jet black to match his aura. Even if this clothing rips, as long as it absorbs his magical energy, it can repair itself.
●Wolf Outerwear: The materials used came from the previous Fanged Wolf leader. But, due to the wolf clan’s evolution, the fur had turned black. As an extra bonus, it seems that the fur had quite some magical energy stored in it. It has tremendous defense power. This attire happened to have become a magic item. It will always perfectly fit the one who wears it. In other words, even if Rimuru turns into his adult version, the clothing won’t rip.
●Swords: Rimuru equipped with a demon sword a Magic Swords a high-purity Demon Steel weapons inserted with high-purity magic stones/gems he created a sword using Bladed Storm Crystallization and Bladed Flame(Scorch): Crystallization from Void God Azathoth call The Sword Of Tempest.
