This study aimed to develop the Romblon legends in comic book form. Specifically, it aimed to investigate the background of Romblomanon legends in the three languages that could be used for promoting Filipino values of children who are still in the process of assimilating the culture of Romblon, investigate ways to conserve and develop these legends into a comic book form and determine the rating of the comic book as supplementary learning resource materials (SLR) in the elementary level as rated by the Learning Resource Management Development System (LRMDS) Team of DepEd. The Evaluation Rating Sheet for Story Book was used in determining the appropriateness of the SLR material in terms of content, format, and technical aspects; and solicited comments and suggestions from the respondents that served as inputs for the improvement and revision of the legends in Comic book form. This paper is a descriptive-evaluative investigation. The research area is the whole Romblon Province. The research sample was determined through a dragnet method wherein key informants, casual informants, and general informants were identified in the field. Evidence was gathered from document analysis and field research. Data collection tools were observation, interviews, and focus group discussions. The research was conducted in five stages: planning, development, validation, final output, and dissemination. Of the four legends, 10 Romblomanon values were extracted and incorporated into the stories. It is highly recommended that the streamlined five-stage development process may be used for the comic book development of the rest of the undocumented legends of Romblon.
