** In Episode 47, Rimuru orders Veldora to keep Milim at bay during their fight against Clayman. When he gets enough of a breather to check up on Veldora, he's [[https://www.youtube.com/watch?v=wRupVm670YQ seen]] spamming [[Franchise/StreetFighter Hadoukens]] at Milim, then pursuing her in the air with a {{Shoryuken}}, [[HurricaneKick Tatsumaki Senpukyaku]], and a [[VideoGame/VirtuaFighter Tetsuzanko]], finally ending his "combo" with a [[Franchise/DragonBall Kamehameha]]. Rimuru can only watch in exasperation, wondering out loud where he learned all those special moves.

A 2D turn-based role-playing and city-building game called ''That Time I Got Reincarnated as a Slime: Lord of Tempest'' (''Tensei Shitara Slime Datta Ken ~Makoku Renpou Souseiki~'') was released for iOS and Android. A 3D battle role-playing and city-building game called ''That Time I Got Reincarnated as a Slime: ISEKAI Memories'' (''Tensei Shitara Slime Datta Ken: Maō to Ryū no Kenkoku-tan'') was released for iOS and Android on October 28, 2021, introducing two original characters by the names of Shinsha (a slime who self-proclaims herself as Rimuru's daughter) and Izis (a mysterious Witch of Mirrors who can summon alternate versions of ''Slime'' characters). It also had several crossover events with other isekai such as ''Literature/{{Konosuba}}'' and ''Literature/Overlord2012'', with major characters from both being [[TrappedInAnotherWorld brought to]] the ''Slime'' world via dimensional rifts and needing to find their way back while teaming up against inter-dimensional threats.

* MagicSkirt: In the rare instances of skirt-wearing women doing active work, such as Ramiris, Suphia of the Beastketeers, and Milim in her SuperMode [[{{Irony}} (despite her regular outfit shamelessly showing far more)]], their modesty is consistently protected.

** {{Telepathy}} is a very useful tool for communication and understanding, especially if you come from a whole race that possesses it. Unfortunately, this also makes it difficult to properly communicate with someone with whom you can't just instantly share your thoughts with. [[spoiler:Geld bemoans while trying to properly organize and work with the majin prisoners of Clayman's forces that he's been spoiled with how easy commanding his High Orcs are by comparison, as he has to take the time to explain aloud what they're doing wrong.]] In addition, because many monster races have [Thought Communication] even if only between their own kinds, this also means few wild tribes bother putting their histories or stories down in writing, or even learning a written language.

* SurprisinglyRealisticOutcome: Humans (even most evolved humans) need air to breath, and this has been exploited twice. The first was with one of the traps in the labyrinth, sealing off the room in a way no air would get in or out, meaning setting a campfire could asphyxiate you. This was also used by Guy Crimson against [[spoiler:Yukki, since [[AntiMagic Anti-Skill]] has no effect on non-magical fire, meaning Guy burned up all Yuuki's air and he would have suffocated if he didn't realize what was happening and deal with the fire. Yuuki has to outright forcibly evolve his body to a fully-matured Saint, removing his human limits in order to remove that method of attack (even if the fight still goes against him)]].

** The first proper one would be the fight against the Orc Disaster, as it involves Rimuru forming alliances with the various races of the Jura Forest to combat the vast 200,000-strong army.

** The Eastern Empire War Arc involves Tempest clashing against the might of the Eastern Empire.

* WeHaveReserves: In the Eastern Empire War Arc they throw over 2 million soldiers at Tempest and the Empires immense numbers all get [[CurbStompBattle utterly crushed]], [[spoiler: later it is revealed that they were [[XanatosGambit expected to lose (however, winning would have been favorable as well)]] the war but in the process the trauma of the defeat was meant to trigger an [[MookPromotion ascension in some of the survivors]]. However, technically speaking there were no survivors left to do this other than the lucky ones Rimuru was able to revive.]]

* EarlyBirdCameo: Before Shizue is officially introduced in the episode named after her ''Shizu'', she first appeared during the beginning of the pilot episode, where she was sucked into a fire and died... only to be brought into the fantasy world and featured five episodes later.

* MaleGaze: [[FanserviceCharacters Milim Nava and Shion]] are both subjected to this due to Milim's [[{{Stripperific}} outfit]] and [[HartmanHips hips]] and Shion's [[BuxomBeautyStandard ample chest]].

* {{Wutai}}: The nation of Tempest itself, naturally, but the Ogre Village before its destruction and the {{Tengu}} Village also have this aesthetic. {{Justified}} as they were all influenced heavily by [[TrappedInAnotherWorld Otherworlders]] from Japan, with Rimuru admitting many of his cultural developments have been because he wants to keep Japanese culture alive and well to avoid homesickness. Fellow Japanese Otherworlders like Yuuki and Hinata certainly don't complain that they have reliable access to things they love like manga and cuisine respectively when they once thought they would only ever be memories.

* SelfFulfillingProphecy: The reason why the Falmuth Empire attacks Tempest is out of the fear that their growing power and political influence risks destroying their kingdom through taking over their trade system, so they attacked first to prevent that. Due to their actions, Rimuru and his surviving subjects are so enraged that they do indeed use their power and political influence to destroy their kingdom, only instead of doing it indirectly, obliviously, and without violence, they do it directly, intentionally, and ''very'' violently.

After dying while protecting his junior colleague at work from a knife attack, Satoru Mikami is reincarnated as a slime in a magical world. As someone who is reincarnated, he gains the Skills "Predator" and "Great Sage". While strolling around, he meets the Storm Dragon Veldora who becomes his friend and names him Rimuru. In return, Rimuru gives the surname Tempest to both of them and agrees to consume the magical cage trapping Veldora, so that one day they can permanently break Veldora's imprisonment. The mysterious disappearance of the Storm Dragon results in huge consequences as his presence acted as a sort of buffer zone. Meanwhile, Rimuru starts his adventure by traveling, meeting new people, fighting some of them, and turning them into allies by fighting them. He is guided by a mysterious interface, the Great Sage, which teaches him how to use his unique skill, "Predator", an almost limitless ability to eat and assimilate living things and objects. Rimuru begins to adopt the forms and abilities of everything he absorbs, which makes him very strong, but also a target.

* WhamLine:
** Episode 47: As it becomes rapidly apparent to Clayman that he has been {{Outgambitted}} and forced into a fight with Rimuru and his subordinates that he can't win, he attempts to [[spoiler: order Milim to kill everyone so that he can escape]], the following line hammers home just ''how'' thoroughly Clayman was played.
--->'''[[spoiler:Milim]]''': [[spoiler: [[NotBrainwashed Why would I do that?]] [[PretendToBeBrainwashed Rimuru and Shion are my friends.]]]]
* WhatKindOfLamePowerIsHeartAnyway: Otherworlders get [[NewLifeInAnotherWorldBonus powerful skills]] based on their desires when entering the world. For Satoru though, he was dying as he was being reincarnated into Rimuru, so his thoughts and desires are a jumbled mess of thoughts like "my god it hurts" and "I can't believe I'm dying a virgin", which the world interprets in weird ways, thus resulting in the skills he gets and the form that he takes. And as the Otherworlders summoned by Farmus prove, the kind of people who get powerful combat skills aren't necessarily the good kind.

* AuthorAppeal: The author very clearly has a thing for cute monster girls, including BizarreSexualDimorphism with dragonewts and eventually including hot demon girls.

* SpottingTheThread: During the ''ISEKAI Memories'' crossover event with ''Literature/Overlord2012'', Rimuru makes a comment about needing business cards when introducing himself to Ainz as a personal in-joke, only for Ainz to not only ''know'' what business cards are to the point of musing he should have some made, but the way he says it reminds Rimuru of a "business man" rather than "skeletal overlord".

** The second opening of same season also showing the remains Great Demon Lords like [[spoiler:Dagruel, Dino and Luminous Valentine]]

* AwesomenessIsAForce: Downplayed with King Dwargo who is described by Rimuru as 'exuding an aura of raw power'.
