Somewhat similar animes with the main similarity being world development. If you are a fan of Overlord you will most likely be a fan of Slime. In both animes the main character is overpowered and that is used as a plot device for world building and domination. The main difference is that Overlord is somewhat more "grim".

The main characters are reincarnated as a monster with video game like abilities in a different world or realm with lots of different life forms. They have memories of their previous life. They both level up.

Both stories involve protagonists originating from Japan and being transported to a fantasy world with superhuman powers, which propels their power as a monarch. They establish cities with locals, mainly monsters, and come into conflict with fellow humans. Both has comedic moments throughout the story. 
report Recommended by Aleron
Both are stand out shows in their seasons for being Isekai's that both play with the viewer expectation in a simple way. Changing the status quo in small ways that aren't particularly mind-blowing, but effective and utilized to each of their strengths

Main protagonist dies and reincarnates into a fantasy world with swords and magic with his previous life's memory intact. Protagonist is trying to navigate the new world based on their previous experiences. Lots of ecchi-comedy moments and has huge character development for the protagonist since after all in Tensei, protagonist is a slime and in Mushoku Tensei, the protagonist is born as a baby.

They both involve having to get used to a new way of living. Starting a new society. Working together and building a society.

- Overpowerd Main Character - Badass Main Protagonist - Genre: Isekai - Closed to being in an RPG, "Time that I reincarnated into a Slime" but plot twist, he's rather thrown to be on the Monster Side than the Human side, wouldn't considered much being a villain however "Arifureta" is meant that the main character wants to go home to his normal world but instead he has the power to kill gods.

Both titles feature adult protagonists in seemingly small and “weak” characters, prone to discrimination and underestimation. However, they have used their charisma and knowledge of the real world to improve their situation in the new world, gaining admirers and recognition but attracting danger at the same time. The stories are wholesome and share an almost too “friendly” approach in style, using prominent themes of trust, friendship and family. Ascendance of A Bookworm is more female-friendly as opposed to “Slime” since the latter features a harem (not over the top), big-busted women, and more action. Nevertheless, the attention to world-building and pacing are similarly well done.

Probably has been said but both have neat similarities. Both protagonists transported to a world to establish, create and maintain a new type of society that benefits the world they were transported in. Both go through a multitude of trails and tribulations but goes in with an outlook of not just positivity, but an ideal to better others. Both world are vibrant, colorful and intriguing cast member and both have stories that go to interesting places that is entertaining.

Both are isekai anime, which have similar take on that kind of show. They don't take itself seriously and have some great comedy moments. "Tensei Shitara Slime datta Ken is like Konosuba but with overpowered main protagonist" is how I describe it to most people. If you enjoy either of these shows, you should check the other one out.

Both are rather OP but relaxed about it Both MC's get put into another world after they died Both involve slimes (Tensei the MC is the slime; kami the MC collects them) Kami is more slice of life with more relaxed vibe. Tensei has more combat but still is about the nice chill moments.

Slime? Yes An anime about slimes "TenSura" is about a literal slime, while "Slime 300" is about fighting slimes. Nevertheless, both series focus on how a person can be so powerful through the influence of slimes.

- Isekai. - Overpowered protagonist. - The power of friendship. - The protagonist gathers some kind of a "family" from supporting characters around him. - Has a fairytale vibe when almost no one from supporting characters can die for real.

Both are Isekai anime. If you like this kind of stories, you will like both. Although re-zero has an slower start, and Tensei Slime has a really quick start, both are really good anime.  
report Recommended by hobbito
- simply: very similar overall vibe - main character gets isekai'd - main character makes a lot of allies due to helping them, unintentionally gains people's respect and they start treating them in a special way - most people become friends with or love the main character - focused mainly on those friendly relatioships - the type of anime you'd watch to relax after a long day - maybe not the same, but I'd say that a similar colorful art style... [other than that, Slime is more serious/fantasy&magic/fight focused, Otome is more light/romance/slice of life, i guess] 
report Recommended by Alesko
If you liked the town-building/politics parts of Slime Tensei, then you'll probably also like Realist Hero, since that's a big chunk of the story. Realist Hero does have action/war parts (because, you know, politics) but a lot of the focus is on the town-building (which honestly I'm all for).

It'd be pretty obvious ofc, Reincarnated as a Slime and Sword are closely similar to each other. They have the following: -The title itself is closely related to each other. -Both MCs have same skill but in different approach. -Skill sets are quite same too. -Monster hierarchy are pretty much the same. Overall, if you enjoy watching a unique isekai anime with vast powers, skills and wild adventures, then its a must watch!

Similarities: 1. Both MC started their ordinary lives as adults. 2. Both found themselves in an alternate world where they have to start from scratch. 3. Both were able to become powerful mage. 4. Both have a couple of harem members. Dissimilarities: 1.

One has a kaiju as part of his team while the other doesn't,

Both isekai animes have OP characters as their main, and also focuses on world-building while leading an army.

- OP main character with a "happy-go-lucky" attitude - Set in medieval fantasy world - The early arcs concentrate on building the "crew" around the main character - General vibe and color scheme are similar. - Both shows can take themselves seriously when they want to, but there's always room for a bit humor, too. - distinct and interesting side characters

- Both have protagonists that are ridiculously OP - Both have magic involved - Both protagonists share their magic with their followers, allowing them to earn respect and build empires. - Both have some comedic moments (at least I think so) Tensei shitara Slime Datta Ken is a fantastic anime and yes, ML is overpowered, but he is pretty humble too. This show also has 2 seasons (but if you count season 2 part 2 as a third season, then 3) and a movie!

They're both isekai anime. If you like the genre, you will probably like them both. They are both mostly light-hearted shows, and the protagonists don't take themselves too seriously most of the time. The both have absurd moments that make you laugh out loud, and they both throw some unexpected things your way (tsundere dragon, how to get closer during a summoning ritual).

Both main characters start off weak and progressively becomes stronger, gaining new abilities and gear by battling monsters. Both main characters hide their true strength. Solo Leveling seems to be inspired by Tensei shitara, in the sense that both of the main characters interact with a system UI unique to them. Both animes are set in a fantasy MMO RPG like world, with Solo Leveling being a crossover between the modern world and fantasy. Tensei shitara focuses on character development and world development. Solo Leveling is mostly focused on character development, but both animes still have a similar vibe.

Same concept, a useless body collects different skills by absorbing/defeating and becomes powerful. While slime relies mainly on skills, in the fruit of evolution it has more like a RPG levelling system.

the amount of politics in these 2 anime is simmilar as in the poweplay between the different nations. gate is about a nation trying to civilize a different world as in teaching and integrating modernday values into an seemingly uncivilized world, and slime is about a creature starting his nation in a similar world to be honest but we get more content about the relations between the different species in slime.

They are both animes that put a very unique twist on the Isekai genre. And focus a lot on the world-building instead of an overpowered MC. Granted Slime does have an overpowered MC but it still makes up for it by the effort it puts into the side characters.

A 30 year old man is transported to another world! Unfortunately the action from Slime is not translated into the farming life presented in Kaiko Sareta Ankoku Heishi... but village development and fan service definitely is. While Kaiko may have more fanservice than Slime, the evolution of a settlement from humble beginnings to prosperous living is shared between the two. Though slime has more of an action tag to it, Kaiko has more of a slice of life feel. Both share comedy equally and hopefully will fill that hole that both of these series leave after you finish them and/or anticipate another season.

Both have action , fights , and fantasy and a very interesting story , although completely different from each other . One is darker than the other , where the MC trains hard to become strong and protect his remaining family while the other might seem a bit more chill , where the MC is OP but the MC has something to protect too . Either way I enjoyed both very much , both are , to me , very good anime

A relative nobody gains an incredible power and uses it to influence geopolitics. In Code Geass the power is more limited, creating a tenser story, and the tone is pessimistic rather than optimistic.

Although the theme is different, the struggles of main characters are similar, which is non existent. The main characters are never in trouble, because both are genius and overpowered. They are surrounded by people who revere power more than anything. I think these two series are similar but in a bad way.

Both anime share a super strong main character who can pretty much do anything with magic. Both have a focus on empire building. Both Main Characters have strong friends that look up to the MC. Both anime are also pretty laid back, but Reikenzan has less adventure and a stronger focus on training to become better

Both anime are incredibly wholesome and fun to watch while Tensura shows some action and wholesomeness, Barakamon shows us the daily life of the protagonist and wholesomeness. In short both stated anime are incredibly unwinding and can be watched at a quick pace.

Both present a magical setting. A vast world of mystery and monsters. I always found myself entertained while watching each episode. How the characters solved their problems, the locations they visited, Rimuru´s humor, Elias´s wisdom and mystery. Both series share the bonds of family. Rimuru builds up the goblin village and eventually more residents of different races settle there. He will seek solutions to protect his citizens and if necessary resort to violence. Elias sees Chise as his familY, and i believe he cherishes her more than anyone or anything. :)

- Both anime have an overpowered main character who is laid back and knows about his power, both have a sense of justice and righteousness - Both anime have multiple comedy scenes and very memorable supporting characters. Both of them form an entourage of powerful friends who aid them in battle. - Both characters attract powerful enemies and hence both anime have mutiple fight scenes -Both anime have a power ranking system (SS Rank, A rank etc.) - However, unlike OPM, Rimuru's power grows steadily during the series whereas Saitama is OP from the start - Also, Slime has much more world building than OPM

Both series involve overpowered protagonists that you end up rooting for regardless, due to the shows' abilities to focus on minor characters and their growths alongside the MC. As well as this, both protagonists kinda involve some sort of progression that you get invested in; with Slime you end up rooting for Rimuru's village's growth; with One Punch Man you end up rooting for Saitama's recognition in the Hero Association. All fights are full of hype- especially the ones where you know that the protagonist wins, and acts as catharsis when you see the villain finally get beat up.
