Batman Cosplay Breaks World Record
A monster-effects artist from a small village in County Galway built a Batsuit with more real gadgets than the Batcave itself.
Julian Checkley, a creature-effects specialist based in Spiddal, Ireland, spent years turning a hobby costume into something Guinness World Records couldn’t ignore. His homemade Batsuit, modeled on the armor Bruce Wayne wears in the video game Batman: Arkham Origins, packs 23 working gadgets into its belt, gauntlets, and chest plate. In August 2016, Guinness World Records certified it as the suit with the “Most functional gadgets on a cos-play suit,” a title Checkley earned through raw engineering rather than screen accuracy alone.
- Checkley’s Batsuit carries 23 functional gadgets, including a fireball shooter, a folding Batarang, a grapnel gun, a Bat-Signal projector, and a 2,000-watt EMP strobe stun gun built with an electrical engineer.
- Guinness World Records certified the record in August 2016, and it was published in Guinness World Records 2017: Gamer’s Edition that September.
- The suit was 3D printed and cast in flexible urethane rubber over a custom undersuit; fully geared up with the cowl ears, Checkley stands 6 feet 10 inches (208 cm) tall.
Building the Suit
Checkley didn’t sew a costume — he engineered one. The armor pieces were designed digitally, 3D printed, then molded and cast in flexible urethane rubber so the plates would move with his body instead of cracking like hard plastic cosplay armor often does. Everything was mounted onto a custom-built undersuit, the same approach effects shops use when building screen-ready hero suits rather than convention costumes meant only to look good in photos.
That construction method is part of why the height number matters. Standing 6 feet 10 inches (208 cm) once the cowl ears are on, Checkley already cuts an imposing silhouette before a single gadget activates — closer in scale to a real-world giant than to the average Comic-Con Batman.
Twenty-Three Working Gadgets
The record wasn’t for the best-looking suit — it was for the most functional one, and Guinness counted every device that actually worked. Checkley’s utility belt and armor conceal or deploy a fireball shooter, gauntlet video screens, a Bat tracking beacon, a Bat-Signal projector, a folding Batarang, a grapnel gun, a cowl respirator, a pneumatic tranquilizer gun, and an ultrasonic anti-dog device.
Beyond those, the suit hides four Bat shurikens, a UV lamp, ball bearing grenades, a gauntlet flashlight, a medical kit, a battery pack, a laser designator, a Bat-cam, a gas dispenser, smoke bombs, a “Bat flask,” a concealed laryngeal microphone, and a two-way radio. The most technically demanding build, by Checkley’s own account, required outside help entirely.
Checkley collaborated with an electrical engineer to produce the suit’s most complex component: a 2,000-watt EMP strobe stun gun.
Guinness Recognition and Gamer’s Edition
The record wasn’t a viral internet claim — it went through Guinness World Records’ formal verification process and was certified in August 2016. It then appeared in print the following month, in the Guinness World Records 2017: Gamer’s Edition, the annual volume the organization dedicates specifically to video game-related feats and stunts.
Stephen Daultrey, editor of the Gamer’s Edition, singled out the build for pushing past typical convention cosplay. According to Daultrey, the suit took “the meaning of cosplay to a whole new level” — a distinction Guinness reserves for entries that involve genuine technical achievement, not just visual craftsmanship.
Checkley’s approach sits closer to the world of practical-effects fabrication and functional prop-building than to costume tailoring, the same territory where makers push 3D printing and custom electronics into other unconventional builds, from personal flying vehicles to full animatronic rigs. It’s also worth noting how his listed height stacks up against other record-book entries built around human scale, including Robert Wadlow, the tallest man in recorded history.
Checkley’s Batsuit still holds the “Most functional gadgets on a cos-play suit” title, and it remains the version to beat for any cosplayer looking to out-engineer him — not with a better paint job, but with more gadgets that actually work.
