Technically Rimuru is genderless, but identifies himself as male (due to his previous life) Rimuru was male in his previous life and still more or less considers himself as such.
Rimuru becomes the Demon Lord in the Birth of the Demon Lord Arc. This happens after he sacrifices 10,000 enemies to revive his friends by becoming a Demon Lord. Long Answer: When does Rimuru become a Demon Lord? In the Web Novel, the Birth of the Demon Lord Arc is the fourth arc in the story. It takes place after the Life in the Royal City arc.
Rimuru Tempest can beat Milim after engulfing and acquiring the powers of Veldora, thus becoming a true dragon. With this strength, Rimuru surpasses Milim, the oldest demon lord in the series. By the end of the series, he attains Godhood and becomes the strongest character.
we don’t know what the Grand Priest is capable of but he probably can blitz Anime Rimuru. Against Manga Rimuru, Rimuru might have a chance but I doubt it. Against LN Rimuru if the Grand Priest fights like the rest of his verse(brute force) he loses(Rimuru is immune to physical attacks and can eat infinite energy)
One of Rimuru's most essential abilities of all is the Predator skill, and this particular skill is what allowed him to gain most of his other powers. Rimuru was reborn with the Predator skill, and he used it to devour many giant monsters inside that cave, including Veldora the storm dragon.
This particular strength doesn't come up often, but from time to time, it can be rather helpful, and it's an advantage that few organic anime characters have. Rimuru Tempest may look human, but he is truly a slime, and slimes do not need to breathe air or filter oxygen from water to live.
Not many anime or comic book characters are telepathic, and this power can give someone a serious advantage, such as Professor X of X-Men fame. Rimuru has telepathy as well, mostly because his default slime body doesn't have a mouth or lungs for regular speech.
During Season 2, Rimuru was getting ready to confront his nemesis, Demon Lord Clayman, and he needed a way to intercept Clayman's army in the Animal Kingdom right away. It was too late to march his army into position, so Rimuru decided to use teleportation magic.
Rimuru has to be more than a fighter -- he must also be a skilled politician and diplomat, but his human life didn't prepare him for any of this. Rimuru is slowly but surely learning the ways of statecraft and politics, and he has a helpful guide on hand.
Rimuru has made many powerful allies by now, and each of them is a formidable asset. In fact, an alliance with any one of them would make Rimuru overpowered by this world's standards, and that includes Rimuru's alliance with a primordial demon known as Diablo/Noir.
There used to be ten Demon Lords in the world, from Clayman and the fairy queen Ramiris to Leon Cromwell and the harpy queen Frey. Later in Season 2, Rimuru took part in Walpurgis, or the meeting of Demon Lords, and transformed it.
Rimuru Tempest, formerly known as Mikami Satoru, is the main protagonist of Tensei Shitara Slime Datta Ken. He is the founder and King of the Monster Country.

I do have to preface this one with “Rimuru has yet to show his full Demon Lord abilities at the time of writing this”, as the matchup is already insanely close without more power-ups.
This fight largely depends on whether Giorno can get close enough to Rimuru to activate his Golden Experience Requiem.
Think of Anos as a slightly different Saitama in terms of power, as he has some of the most intense feats in all of anime.
I hope this goes without saying, but Mob would have to be at 100% with the full intent to kill in order for this to work.
Since we talked about Mob, we might as well get his older brother out of the picture.
For all intents and purposes, Urashiki is currently just a slightly better version of Rimuru.
If you thought the Eri pick earlier was too much of a stretch, this one should suit you better.
Gobta is a casual friend of Rimuru's, being one of the first people who ever allied with him, and Gobta will do anything for his slime boss and friend. Gobta is a bit arrogant and goofy at times, but he still values his friendship with Rimuru, and he'd rather fight in Rimuru's name than his own.
The masked hero Shizue Izawa only spent a brief period of time with Rimuru before her time came, but she and Rimuru did get along quite well before she passed away. Shizue is an isekai heroine like Rimuru, who came from World War II-era Japan. It was Demon Lord Leon Cromwell, in particular, who summoned her here.
Not all Demon Lords are hulking brutes. One of the oldest and strongest Demon Lords is Ramiris, a fairy who crossed paths with Rimuru late in Reincarnated as a Slime Season 1. She and Rimuru clashed at first, but they soon became friends and political allies.
The ogre warrior Benimaru may not be Rimuru's BFF, but he is certainly a loyal and fearsome ally of Rimuru's, and the two of them get along just fine on a personal level. Benimaru may be the ogre tribe's leader, but he puts Rimuru first, and Rimuru is thankful for the support.
Shion is another member of the ogre tribe, along with Benimaru, and she is fanatically loyal to Rimuru on a professional and personal level alike. Rimuru finds her flamboyant and immature personality tiring at times, but he wouldn't dare kick her out of Tempest. He's glad to have her around.
Another friendly ogre is the lovely but tough princess Shuna, the younger sister of Benimaru the warrior. Shuna has been a loyal and committed member of Tempest since the early days, though she isn't often seen in battle. She would rather handle more constructive affairs in her new home.
Dogs are known as "man's best friend," and in this isekai world, star wolves are a slime's best friend instead. Ranga once belonged to a bloodthirsty pack of wolves led by his father, but then he allied with Rimuru and the goblins. It was a wise decision.
