Zettai Karen Children

Both of these hyper comedy series were produced almost by a lot of same staff. Notice the similar format in on-screen advisory, commercial phrases, lyrics mark-up, etc. 

explores relationships between normal people and those with superpowers 

Both shows deal with the concept of kids with psychological powers, having certain levels, whether they are too powerful or not to be part of society, or if a seperate place is needed for them. They also feature for the main characters, girls. 

superpowered fights explores relationships between normal people and those with superpowers 

science fiction and superpowers concerns relationships between normal people and those with powers 

* ESP power * fight between good and bad espers * two leading "races" in universe: normal people and espers 

Both place children with powers among those with no super abilities. Both have antagonism between groups. They share an element of hope for overcoming differences.  

These share quite some elements: A group of 3 girls in their early teens with superpowers fighting side by side. A guy in his 20ties as guardian. Loli and other jokes. Cool antagonists, with the evil overlord the coolest of them all. The overlord is trying to change the world, and the protagonits oppose him and his underlings or allies. I found these series sometimes of bad taste, but never boring. Would recommend them both. 

Both series are about superpowered children fighting against superpowered foes in a world of espers and science. The kids in ZKC are gradeschoolers rather than middle schoolers but are part of an elete force that combats esper criminals. ZKC is however less serious than Railgun for the most part however, often protrayed through the fact that 'the children' are bratty and abuse their powers a lot. 

Both Anime orient around the day-to-day lives of three school-age girls' in an unfamiliar or overblown situation as they are special. Due to their "specialty" they are used by organizations for the better of mankind. Both containing themes such as: - Reason for being; "Am I a Puppet/Weapon for this organization?", etc. - Discrimination; Inhuman Powers/Genetically engineered. Discriminated against for being above human. - Family; E.g. Being with those they love./ Non-"traditional" family. - Life Lessons; Growing up in the world you're faced with and overcoming the hardships. - Female leads - "School" setting; Principles, vice-principles, teachers & students. - "Zettai Karen Children!"; "Absolutely adorable Children" - Kids are cute, and you'll end up feeling like a parent. The style seen in Zettai Karen Children is unlike any I've ever seen before. That is to say it's unique in a good way. With around 50+ episodes this anime is very paced which allows for the lengthy character development within its large and diverse cast. Despite the large cast every character is entirely original in their personalities, they all live as "one-big family" within the (often cramped) confines of the HQ. Which almost always leads to havock in the event of a misunderstanding, its these type of episodes which stray from the main-story which make the characters come alive. It is quite literally the Hogwarts of Zettai Karen Children. But the large cast isn't everything this series has to offer. Its main arc focuses around the clash or two organizations, with neither really being the villain. Episodes which show Kyosuke as the protagonist lead to the HQ of the Psychic Squad being the antagonist and vice-versa. Thought quite limited in their frequency these episodes change in pace vastly from the norm, usually leading the squad of girls confused as to whom they should believe in[Life lessons]. Though generally these are always entertaining to see. Overall, it may be too early to say as I've only seen the two latest episodes of Coppelion, though with the way this anime is structured it should be quite similar enough for viewers to also like Zettai Karen Children. This was my first review so I apologise if this is poorly presented.  read more 

Both series involves around espers that are measured by levels that determines their degree of powers. Both series' main male protagonist has similar personalities and are protective to those he cares about. They often go through lengths to help others in need. Both series features some super power themes and antagonists who also has their own supernatural abilities. Both series also contains comedy, drama, and even some romance. 

Both have a self-centered main heroine, both involve a family situation with superpowers, and Ouka and Minamoto are very similar characters on the surface. 

Both feature young girls with psychic powers that are misunderstood, as well as an older mentor figure who is the one person there for them. While Zettai Karen Children has a lot more comedy in the beginning, it moves into a more drama-focused story in the latter half. 

Children that don't know how to control there powers and act very prematurely. These shows are directed a kids and very similar styles with an eccentric villian... 

These two animes have a slight simillarity when it comes to psychic abilities. In Terra e, those who possess psychic power are called Mu's while on Zettai Karen Children they are called Espers. On top of that these people who possess these psychic abilities are somewhat hated by normal people. 

I really don't know why, but the first half of D.Gray-man and the whole of Zettai Karen Children sort of feel similar even though ZKC is no where near as serious as DGM. Allen and Shiho are pretty similar to be honest as well, which I find funny xD and both series are pretty lolsome too. 

These deal with the idea of special powers. Particularly those with children, and wheter or not the children should be treated like normal children, monsters or gifts to humanity. 

What would happen if humans were to develop powers? Each of these shows take a slightly different view point on if this should happen and how normal people would react, from the view point of those with power and those likely prejudiced. 

Both share the same kind of comedic atmosphere plus they both share half the same seiyuu cast. 

Not really great comparison about those two series, but the characters is a lot alike. 3 children loves one man, who refuse them. 

CLAMP Gakuen Tanteidan + Zettai Karen Children = Tantei Opera Milky Holmes Take the characters in Zettai Karen Children and in the concept of a Detective School like CLAMP, you get TOMH 

Both have groups of powerful girls managed by a bishonen glasses-sporting older man who's not as strong as they are.
