Monster and 20th Century Boys are both written by the same author (Urasawa Naoki) and are both heavily psychological works that primarily explore the nature of evil.

Both are written and drawn by Urusawa Naoki, and has the unique Urusawa feeling. They are both about a "mystery" of sorts, as well as a conspiracy that threatens the world. Billy Bat has some supernatural elements and is more of a historical manga set during the 50s-60s.

The two pieces are emotive in two particular ways: a coming-of-age realisation, and the development of relationships between friends. Both also feature great artwork and storytelling.

You will find yourself mesmerised by the amazing storytelling, dramatic character development, and the enveloping mystery of the plot in these two publications.

Both stories are thrillers that are a race against time as the protagonist has to remember events and people from his childhood to protect himself and those he cares about. They definitely have the same kind of series-long tension that keeps you reading late into the night.

Both are about surviving almost extinction due to several reasons, and how society changes and adapts to it. Furthermore, both are also about groups of people unraveling the mysteries surrounding the events of their almost extinction. In both manga we witness the growth of the different characters over long periods of time.

A bunch of kids saving the world, do note that Bloody Monday is shōnen unlike 20th CB.

The characters in both are involved in a life or death game. The "game" in 20th century boys involves the entire world, while Liar Game is much smaller. Both focus mainly on psychological conflits and character development. You need to actually think to understand the story of either

Friends...Comrades...Both manga are about a male who has to deal with something or someone trying to take over the world. In one story, it's about one of his childhood friends trying to brainwash everyone and in the other, it's about his friend who wants to make everyone disappear. Both are thrilling action/mysteries that are addictive and filled with serious topics and a moving plot.

"What the hell is going on?" is usually the thought that comes to mind when first reading either. But each mystery and loose end is slowly unraveled as the story progresses. Both mangas heavily focus on psychological conflicts and character development but only Believers includes adult interactions and erotic behavior. In both stories, a bizzare cult is at fault for the several occurring deaths and disappearances. Standing at the top in 20th Century Boys is "Friend", while in Believers a man called "Master". Both protagonists are deeply connected with the cult, but approach it differently. Kenji seeks to find "Friend" and put an end  read more

Yes I did it. While reading this manga I couldn't help but feel the subtle influence of Otomo's masterwork in what I would be tempted to call it's spiritual successor. The main similarities, aside from the obvious seinen and sci-fi that both of these prolific works share, is how the story progresses. The enormous cast of characters that grow and change as the story progresses in each work, much like the narratives propel the plot forward at a dizzying pace though in a good way. If you're a fan of psychological science fiction and manga than you are doing yourself a discredit if you  read more

The main plot of both these series convey the meaning of friendship and trust. Both the main protagonists have their true friends as their supporting force.

The people are forced to be a part of a 'game', the purpose of which they aren't told. Both protagonists seek to find the "bad guy" and aim to end the senseless game in which they were plunged into unknowingly.

ERASED and 20th Century Boys both are great mystery-seinen manga that looking for someone who responsible for the tragedy on both series. The plot of these manga are really similiar, the main characters are adults and both of them must remember an event since they were child (ERASED's MC even uses time leap).  
reportRecommended by HiatusXHiatus
Antagonists hold a lot of power and the main characters have to oppose this massive force while trying to find out the truth behind everything that's happening and will happen while trying to keep it a secret from others. Both give off the feeling of suspense and leave you impatient to know what will happen next.

Both mangas are high-adrenaline thrillers with a touch of mystery. In a world where rebellion against societal norms can get you killed, the main characters are pitted against greedy and corrupt enemies with terrifying political and economic power. Colorful characters, masterful cliffhangers, and powerful stories make these two mangas a Japanese thriller must.

Both are seinen manga with touches of sci-fi that focuses mainly on psychological conflits and character development. Also, their brilliant plots feature end-of-the-world and conspiracy ideas. Even the feel is the same. 
reportRecommended by Leninha
Each of these manga deals with an epic adventure with a protagonist, who against the odds, fights against an absolute evil. Shin Angyo Onshi is more of a historical story involving Korea and 20th Century Boys is more based on current times involving Japan. ^_^

It has a similar theme:"man relives his childhood" 
reportRecommended by Sylphonsso
Although one is manga the other is a manhwa, both of them have great similarities. Throughout the stories lots of mysteries happen and some "friends" try to solve the mysteries.

In a world where hopelessness has blended into everyday life, a dystopian tale about some teenagers and their struggles. Anyway, frankly speaking, there really is no hope; the earth is about to end. 
reportRecommended by Fabio
Different genres, but with a similar feeling. Mysteries that span decades, and huge twists in almost every chapter. Both masterpieces. 
reportRecommended by Wildflame
Both are seinen manga, with plot about the past, in school, and later, as adults. Nijigahara Holograph is a lot shorter though, only 1 volume. 
reportRecommended by Kupo28
Too similar, both are a psychological mangas and have a complex story. Also both , Urasawa and Mizukani, use to have complex characters, incluiding the supporting characters, with much importance in story.
