SAN DIEGO — K-pop group ENHYPEN joined Catherine Hardwicke, director of the first “Twilight” film, and franchise actors Peter Facinelli and Ashley Greene at US' biggest pop culture convention, Thursday.

More than 120,000 people are expected at the four-day convention, which began in 1970 with a gathering of several hundred sci-fi and comics fans and an in-person appearance from Marvel icon Jack Kirby.

The band joined a Thursday panel about vampire storytelling. It marked one of many moments of cross-pop culture exchanges.

Members of distinct fandoms unite through cosplay, showing off handmade costumes and exchanging photos. Brionna Slavalk, 27, traveled from Indiana to attend the convention dressed as the elf paladin Vaelus from “Critical Role,” a Dungeons & Dragons-themed web series. Her skin was painted purple.
