Edens Zero

Both series are about a group of friends pursuing exciting adventures and using magic powers to defeat their foes. Both have main characters that are very similar to each other (personality and design) and heavily rely in themes like family and friendship and also have plenty of fanservice/comedic moments. Lastly, Fairy Tail and Edens Zero were created by the same mangaka. If you liked Fairy Tail, you will probably like Edens Zero. 

Both have similar themes of friendship and adventure. They travel to different locations with their own cultures and both have a strong sense of exploration with friends. 

Both shounen has the protagonist and his team searching for something Both anime can go from having joyful adventures to even dark and depressing themes  

Both anime consist of a team of quirky and fun characters traveling in space They both have either dark and/or joyful moments Both have aesthetically pleasing space themes along with fan service and funny scenes  

These shows aren't super similar but what they do have in common is that they're shounens directed to a younger audience (10-13 year olds). Both shows have their fair share of ecchi elements but thats standard for the shounen genre. So yeah if you like edens zero you probably will like shaman king :) 

CHARACTERS ARE ALMOST THE SAME FROM FAIRYTAIL ...BUT THIS TIME ITS SCIENCE -FICTION BASED GENRE.  

-the sense humor -the fights and abilities -made by the same author -Both have some dark moments  

Space adventuring from one planet to the other in search of a superior universe goddess to grant wishes. Presence of androids with hearts. 

Similar types of adventure story about seeking a a being (or objects that lead to a being) that can grant wishes. In Edens Zero, Shiki was raised by robots and meets female V-Cuber Rebecca, they go on an adventure to find "Mother", a goddess who can grant wishes. In the Pilaf Saga of Dragon Ball, Son Goku was raised by a human man and meats female adventurer Bulma, they go on an adventure to find the seven dragon balls that can unlock Shenlong, a dragon god who can grant wishes. 

Both shows are about a galactic adventure where an idealistic main character wants everyone to get along well. Both also have a giant female figure known as "Mother" that is key to the plot of the story. 

The characters in both shows venture in space together. They have very different plots but similarly in every planet they visited. There are always new adventures to see and do. 

Just ignore the fact that both of these shows have names that end in "Zero". I noticed that myself and thought the similarities ended there. They don't. Both are dark fantasy anime that serve as deconstructions of their respective genres ("Edens Zero" of shonen battle anime, "Re:Zero" of isekais). The main character in both shows has spent most of his life in isolation then one day gets thrown into a vast world that they're eager to explore, only to discover that said world is much harsher and more unforgiving than they initially believed. Personality-wise, Shiki and Subaru are generally cheerful and friendly, but also socially inept and try way too hard in certain aspects (Shiki at making friends, Subaru at pleasing others). In both cases, they end up making friends with a sweet girl with a bad reputation (Rebecca/Emilia), who has a cat-like companion that serves as her aid in combat (Happy/Puck). They also have a few of the same voice actors- Shiki and Subaru are voiced by Sean Chiplock, Rebecca and Beatrice are voiced by Kira Buckland, Pino and Felix are voiced by Sarah Williams and Weisz and Roswaal are voiced by Ray Chase. Personally, I recommend watching both, as the two of them are equally good in pretty much every way. read more 

I'm going to be biased on this part... both animes aren't that great. butt if you like one, you'd probably like the other. -Both main protagonists want to pursue their dream/goal, but their reasoning is very shallow. Despite not having strong reasoning, they are very committed. -Both anime are about adventure, traditional shounen where the characters travel around, meet people, defeat evil that comes across their path -Both main protagonists is abnormally stronger/unique powers compared to normal humans -In Fairy tail and Eden zero vs. Orient and Magi, the original characters of the series are carried over to the new anime they made.
