As the main concept of Homi Bhabha’s postcolonialism, hybridity refers to the area on the borderline overlapping between contrary concepts such as white/black, colonizer/colonized, and west/east which was used to justify Western domination over the East. Hybridity is also presented as ‘in-between’ space, interstitial passage, and ‘beyond’ borderline in Bhabha’s postcolonialism and can have the role of resistance in such dichotomy focusing on the third space/area on the borderline. This study aims to probe into a variety of aspects of hybridity through character, space and so on in On Such a Full Sea. In this novel, the protagonist Fan is a symbol of hybridity as a resistant character who has free will and explores her own future and B-Mor is another symbol of hybridity as an ‘in-between’ space between ‘Charter’ and ‘open countries’. Furthermore, Changrae Lee presents various aspects of hybridity through time, geography, and a narrative voice. Through describing the resistance of hybridity, Lee suggests that individuals should recognize the ‘in-between’ spaces which can be the resistance area to break the dichotomy and the power of community of ‘individuals’ not a single ‘individual’.
