GetBackers

It's quite similar considering that Both Black Cat and GetBackers share a main English Voice Actor (Jason Liebrecht plays both Train and Ban in both series respectively), As well the music is done by Taku Iwasaki in both series. The fact that both series have goofy characters like Sven and Ginji and the more serious character like Train and Ban. Means this is almost a clone of it. 

Super powers. Mystery. Witty. Each anime has these elements in spades. Intensity seems to be the main element though. I couldn't help but notice the similarity after the first two episodes. The darkened theme running through the background plot sets up the mood for future events and the protagonists both have sort of that "in your face" approach. If you've seen one, I definitely recommend the other if only for a comparison of the two.  

in both animes the protagonist will do anything for money, although in get backers it is more to get back something lost or stealed. 

My reason for saying Get Backers is similar to Stray Dogs is pretty simple and straight forward. Without spoiling too much from Get Backers, both have the main character found by a brother like figure, both have a main character that grew up an orphan. Both have a main character with a similar personality(kind at heart) Both have a detective like agency. Get Backers was one of the first, duo/group jack of a all trades detective agency manga, and certainly it did not end up the last, it should be read and watched.  

The similarities between these titles are a bit random but nonetheless very much there. Both series have an overall dark atmosphere but still inject a bit of comedy every so often. Plotwise, both involve a small group of men who go on some sort of retrieving mission. Finally, both are most worth watching for characters and their dynamics rather than any sort of plot or action they contain. 

Both have a group of heroes with special abilities. They fight for justice. They bot have great characters 

Get Backers is more light and comedy than Darker Than Black, but the themes of powers is the same, and both series has main characters that manipulates electricity in similar ways. 

In both series, the main characters take on dangerous jobs/missions as a bounty hunter or "Getbacker" in hopes that their hard work would finally free them from their poverty and grumblings about having no money. Despite being very successful at what they do and completing their jobs, money still manages to elude them and onto the next job they go.  

Get back what is stolen 

They had the same director and they both provide good action and mix of shounen comedy. 

The jobs in both Anime are similar and the characters have similar powers. On top of this the characters have similar personalities. There is also lots of action and similar styles. 

VERY different people work together. A themes of partnership, friendship and mutual assistance were shown very well. 

Wacky humor, similar styles and an ending built up to, not to mention characters one ends up getting to know if not outright fall in love with. On top of this, both are rather well known for their time frame, although they may have also both faded from memory with all the other Anime coming out. 

-do odd jobs -helping their customer -mature art style -main character're sleazy but responsible and caring at the same time 

-Both involve in helping other people with any job no matter how dangerous  

Battle shōnen with super powers, similar characters and a bit of comedy. 

D. Jackal = Bel ( Knifes ) Himiko Kudou = Bianki ( Poison ) Amano, Ginji = Lambo ( Light and Native XD ) Mido, Ban = Mukoro ( Mist )  

They both go on missions to get enough money to barely survive and they both do it with powers 

I think the spirit of K really lies in the competitive dynamic between the different super powered groups. The characters all are exhilarated by their rivalries and violent fights, yet a bittersweet feeling underlies it because of the consequences of their powers. GetBackers has a similar tone. It is a friendship story between two young men whose pasts have been shaped and twisted by their abilities. They encounter many obstacles, but revel in the chance to test their powers. Both shows are carried by this excitement and the emotion between characters as they battle for and against each other.  

Getbackers was probably the first one in mind when I saw Monochrome Factor. Both series showcases an array of bishonen characters, bromance, double/hidden personality (see Akira and Ginji), effeminate characters (see Shirogane and Kazuki), action, supernatural, comedy and the shounen-ai subtext that will make fangirls beg for more. 

Get Backers and .hack//SIGN have a similarity with characters and an initial plot. MacubeX and Tsukasa are both questioning their existence. In Get Backers, however, MacubeX takes his depression to an extreme; while in Tsukasa's case you get a small picture of a bigger problem. Both anime are entertaining in their own right, though Get Backers, not centered around a depressed main character, is humorous; and .hack//SIGN, while centered around a lone speculative child, is more thought-provoking. If you enjoy one you will enjoy how the other looks at the possibility in a different light. 

- Both are in the Shonen category - Main characters are working in pairs - They have the same jobs - Features special powers/abilities With the difference, Re;Hamatora have lolis, while Getbackers have big breasted lady. 

The chemistry and the relationship between the characters They have personalities and similar characteristics, some GetBackers characters seem to mix other Yuyu characters 

The Characters in both shows have special powers. They fight for what they believe to be right. 

In both animes, they have to do something for the rest in exchange of something. Get Backers : A Group that retrieves anything that was lost in exchange of money Ookami-san : A Club that fixes students problems in exchange for the student helping them out later.  

Young GTO (Shonan Junai Gumi) is very similar to Get Backers in that they both feature a duo. In Shonan Junai Gumi , Eikichi Onizuka and Danma Ryuji(Onibaku) both try to find girlfriends and become the strongest gang in Shonan.In Getbackers ,Ginji Amano and Ban Mido try and make a living in becoming retrievers, by helping people "get back" what they've lost. Both animes feature a group of two characters who fight alongside each other against tough opponents and have hilarious moments together. Hope you enjoy them! =) GBbaku - geddit? :P 

These anime have many similarities. In both the character design is good, but the animation quality goes up and down. Both have some genres in common, such as action, drama, tragedy, and some comedy to lighten up the mood, and themes in common, such as granting wishes, fighting with ex-friends, protecting the loved ones, and world destruction. Both can be quite psychological, even though Get Backers has more shounen elements and is less serious than X. Both are about people who have supernatural powers (such as controlling electricity, just to name one). Both have an ensemble cast of characters, and many bishounen. In both there are 2 opposite factions that fight against each other. But above all, some characters are very similar, and many, if not all of them have a tragic past and/or are orphans (reason why grandparents are quite important in these series): there’s the innocent, quiet schoolgirl (Kotori/Natsumi), the cheerful guy (Sorata/Ginji), the computer freak (Satsuki/Makubex), the killer in a business suit (Seishiro/Akabane), the busty beauty (Karen & Kanoe/Heaven), the man who is telepathically connected to animals (Kusanagi/Shido), the blind girl (Hinoto/Madoka), the calm, blonde, and seemingly careless man (Yuto/Kagami), the absolutely amazingly gorgeous guy (Subaru/Kazuki), etc. While the X anime is notably inferior to the manga, I think the Get Backers anime is better than the manga. read more 

If you enjoyed the action in Dragon Ball Z you will enjoy the fight scenes in Get Backers! Like DBZ it has a great cast of wonderful characters with awsome abilities. Enimies become friends, everyone helps out, and like in DBZ, the most powerful character always has a smile on his face! 

Both revolve around charaters with special powers They also just have a similar feel about them it was really worth watching. If you liked one you will like the other! 

~Slap-kneed humor ~Many bishounen ~A group of guys get teamed up to do odd jobs 

The shows both have a rather gothic look and are mystery based. The character designs have simularities, having a detailed look, yet not going overboard with the details. The characters also have depth in the characterization. The two main characters, of the two main male characters, one is serious, one is more comedic. 

A largely unskilled but hardworking girl joins two uniquely skilled guys and does her best to help them out as they work through supernaturally-tinged cases that their unique skill sets permit them to tackle and try to grind down some of their debt. In Zombie-Loan they hunt down zombies that shouldn't be alive; in GetBackers they get back what shouldn't be gone. 

Both have characters that are a little off socially, have strong abilities, and who really like fighting teamed up with characters who fight, but are soft hearted.  

Both have characters who are down on their luck (largely because of their personal preferances in lifestyle) and who are really bad with money. Also the premise of having an agency where people come to you for help is the same, though the details around the main characters are quite a bit different. 

the plot is not at all the same. but it has the animation technique, and many facial expressions are similar.  

Both anime have similarity with people in them. Chosen people have special power, unique to ones existence, and both of them have small organizations who works for money (Get Backers work only in order to retrieve something stolen or lost while in Senkou no Night Raid work as retrievers of information). 

While GetBackers and Gad Guard both go in completely different directions with their stories, they both have the same urban feel and similar character interactions. On top of that, they have similar upbeat music and intense action sequences. GetBackers contains a good bit more comedy than Gad Guard, but Gad Guard still has a fair dosage as well. In conclusion, if you like the overall atmosphere of one of these series, you would probably find a sense of familiarity in the other and like it, at least to some degree. 

Ban mido in GetBackers is kid of the same person in a way he uses his left arm to use make a move called snake bite and Touma Kamijou uses a movie that destroys magic and the are preformed in the same way and people have natural ability's like a girl has lighting ability exactly like Ginji Amano in GetBackers The same ability's but a hole different story and show
