Helio-con celebrates the world of speculative fiction and all who appreciate imagination that remains unrestricted by reality. Helio-con will gather together visionary artists and the community of speculative fiction fans in Denton County and throughout the Dallas-Fort Worth metroplex.


Our mission is to assemble fans of science fiction, fantasy, horror, and alternative realities, their art, their tools, and their supporters to create an exciting, fun, friendly, collaborative, and enjoyable experience. Visitors will explore the awesome, boundless world of the unreal through celebrity guest appearances, book signings, ephemera and collectibles shopping, costume contests, gaming, panel discussions, scene re-enactments, art displays, and raffles.
