'''''I Kill Giants''''' is a graphic novel written by Joe Kelly (who also wrote ''SelfDemonstrating/{{Deadpool}}'' and is a member of Creator/ManOfActionStudios) and illustrated by J.M. Ken Niimura.

Barbara Thorson is a loner. A misanthrope. A girl with a very caustic personality. And she's only in the fifth grade. Oh, yes, and she kills giants.

Problem is, nobody else sees what she sees. Everyone treats her as a freak, and she reacts violently to the counselor, Mrs. Molle, when she tries to find out a little more about Barbara. It takes the friendship of a new girl in town, Sophia, to start breaking Barbara out of her shell....

But is that for the best? Are the giants Barbara claims to kill really real? Is Barbara really just suffering from some kind of mental breakdown, caused by some kind of family trauma? And what does baseball have to do with it?

An excellent work, ''I Kill Giants'' starts weird, gets crazy, then gets CrazyAwesome, and then goes straight into heartwarming. Read it if you need something to read.

Compare with ''Literature/AMonsterCalls'', another story about a troubled loner protagonist that gets tied up with a monster that may or may not exist, also accompanied by a similar BittersweetEnding.

A film version was released in September 2017, starring Madison Wolfe as Barbara and Creator/ZoeSaldana as Mrs. Molle. It is to be released on streaming platforms in 2018.

* TitleDrop: Barbara proclaims this to Sophia.
* UnusualEars: Barbara wears three different pairs of [[AnimalEaredHeadband Animal Eared Headbands]] throughout: [[CatGirl cat]], what looks like mouse or bear and, most commonly, bunny ears, making her look a little bit like [[Anime/{{FLCL}} Haruko Haruhara]] (It doesn't help that the art style is a little similar). The headbands also help to visually distance her from all the other characters and emphasize how much of an outsider she is.
* WeaponOfChoice: Coveleski.
* WeirdnessCensor: No one seems to think Barbara wearing [[AnimalEaredHeadband Animal Eared Headbands]] are out of the ordinary.
* YoungerThanTheyLook: Taylor and at least a few of her lackeys (the former especially) in particular look rather similar to teenagers for girls that are supposed to be in the fifth or sixth grade. However, it is possible that they may have been held back a grade (given some of their record, especially Taylor's) with it being an ElevatorSchool or they only look the way they do because that is how Barbara perceives them.
