Keywords: Implicature, Relevance Theory, and MovieImplicature is what the addresser wants to convey without stating it explicitly. In this study, the writer intends to analyze an implicature in Megamind Movie using Relevance Theory. This study is conducted to find out (1) the explicature conveyed in the utterances of the main character in Megamind movie. (2) The implicated premises and implicated conclusion conveyed in the utterances of the main character in Megamind movie. The writer uses Sperber and Wilson’s theory in analyzing the data.This study is qualitative study since the writer analyzed utterances taken from the dialogue of the main characters in Megamind Movie. Research design is document analysis. From the data obtained, the writer tried to find out the explicature, implicated premise, and implicated conclusion based on Relevance Theory proposed by Sperber and Wilson (1995).In this study the writer found 14 utterances that convey an implicature. To answer research problem the writer gave an example from the conversation that were taken from datum 2. The context of this conversation is when Megamind crashing Metroman’s Memorial Day by kidnapping Roxanne Ritchi. Metroman is threatening Megamind to put him into jail by saying We all know how this ends, with you behind the bars. The word ‘we’ refers to Metroman and all the citizen of Metro city, while ‘this’ refers to the battle between Megamind and Metroman. The last, ‘you’ refers to Megamind. Then, Megamind responses Metroman’s threat by saying Oh, I am shaking in my custom baby seal-leather boot. The word ‘I’ refers to Megamind. From the explicature, Megamind responds may irrelevant. But it conveys an implicature. There are many causes to make people shaking and that creates the implicated premises; Megamind is shaking because it is cold; Megamind is shaking because of terrifying; Megamind is shaking just because he wants to; Megamind is shaking just because he pretends to be. From the implicated premise. It may seem that Megamind terrifies being threatened by Metroman, but in reality Megamind does not fear at all. The intended meaning is he just pretending to be and mocking Metroman by showing his baby seal leather boot. Thus the implicated conclusion is Megamind does not fear of Metroman.The writer draws conclusion that Relevance Theory is concern with ostensive communication that is intentional communication through an addressee that can understand the speaker’s thought. This study hopefully can provide appropriate references for further researcher to conduct the research in implicature. It is recommended for the next researchers to conduct similar studies to be analyzed using Relevance Theory with different object such as novel, magazine or even article.
