Desk jockeys in eye-wateringly tight spandex will blur the line between fantasy and reality this week as they invade San Diego for the world's largest celebration of pop-culture fandom.
The 49th Comic-Con International will revel in movies, television and - yes - comic books as fans in pitch-perfect monster, alien and manga costumes swelter in the southern California heat over five surreal days.
Where fandom abounds, controversy is never far behind.
And the big bone of contention this year is Disney's decision not to bring its Marvel Cinematic Universe to Comic-Con, despite a record-breaking year with Black Panther, Avengers: Infinity War and Ant-Man And The Wasp.
Since its humble beginnings in 1970 as the Golden State Comic Book Convention, a gathering of a few dozen geeks who swopped superhero magazines, Comic-Con has exploded in popularity.
Each July, it attracts around 130,000 cosplayers, movie executives, sci-fi fans and bloggers to a feast on all manner of panels, screenings and other attractions.
Described by Rolling Stone as the "Super Bowl of people who don't like watching the Super Bowl", Comic-Con's beating heart is the 6,500-seat Hall H, where a cornucopia of stars hawk their latest works.
New Line Cinema and Warner Bros kick off proceedings today with Scare Diego, where fans will enjoy insights into It: Chapter Two and the frankly terrifying-looking The Nun.
The convention has traditionally persuaded most of the big studios to turn up for detailed presentations of their highly anticipated slates of upcoming movies - but not this year.
Disney is presumably saving its biggest treats for its biennial D23 fan convention, and Universal's segment is dedicated to just two movies - M. Night Shyamalan's Glass and David Gordon Green's Halloween.
Elsewhere, Paramount brings its spin-off Transformers film Bumblebee, and Fox has a Deadpool 2 celebration and preview for its Predator reboot.
Sony presents Venom and the animated Spider-Man: Into The SpiderVerse, neither of which are considered part of the Marvel Cinematic Universe, although Marvel was part of the production team.
That cedes the center stage to Warner Bros, which is expected to pull out all the stops in its two-hour Saturday spot.
The schedule is kept tightly under wraps, but insiders say there will almost certainly be thrills and spills from Aquaman, Godzilla: King Of The Monsters, the new Fantastic Beasts movie and Shazam!.
The TV side of the Comic-Con gets increasingly bigger as stars follow the voluminous torrent of cash into TV productions funded on a scale never seen before.
This year's Hall H is expected to be more notable for its small-screen content, despite the absence of HBO's big-hitters.

"Several other networks will be showing off new and returning series in a hope to cut through the cluttered landscape and maintain, or possibly grow, viewership," said Lesley Goldberg of The Hollywood Reporter.
AMC has the pick of the convention, with a debut appearance from Better Call Saul, alongside a 10th-anniversary reunion panel for Breaking Bad (2008 to 2013) and a discussion on acclaimed graphic novel adaptation Preacher.
The Walking Dead, the most successful show in United States cable TV history, is back ahead of season nine, expected to debut in October, and there is a panel for its sister show, Fear The Walking Dead.
Other studios plying their TV wares include YouTube Originals and Fox, while SyFy stages what promises to be an emotional farewell to the Sharknado franchise.
Marvel's movie people might be largely absent, but the studio boasts numerous panels and other events for its TV output, including Cloak & Dagger, Iron Fist and Marvel's Avengers: Black Panther's Quest.
