No, really. Tall, pale, long dark hooded cloak, scythe clutched in his free hand. Behind him, in the queue, was the guy straight out of Kick-Ass - skintight costume and everything. You wondered how he was going to manage - there didn't seem to be any zips or Velcro so far as you could see, but it seemed indelicate to enquire any further.
There were lots of causes of double-takes yesterday as the first MCM Scotland Comic Con - the ultimate convention for fans of comics, cult TV and movies - came to Glasgow. The geeks had indeed inherited the earth. Hoards of them, many in costumes that outdid even Death, poured into the venue. Ahead of them lay a scene so unremittingly over-crowded that the average battle scene from Lord of the Rings looked poorly attended by comparison. Estimates put the gate figure at around 10,000.
Some of the costumes were fabulous: there were Ewoks, Wonder Women, Hit Girls from Kick-Ass, skeleton kids, Harry Potters and even a Gandalf or two. There was an Austin Powers in a crushed velour, or perhaps velvet, suit. There were scores of impressive manga, anime and horror-movie costumes, not all of which could be readily identified by the non-hardcore fan.
One young man went for the low-tech approach - a cardboard box around his chest with "Gundam" scribbled fore and aft, necessitating a quick check with Wikipedia, which helpfully revealed that the Gundam Series "is a metaseries of space opera anime ... that features giant robots (or 'mecha')".
There were parents with small kids in tow, several teenagers offering "free hugs", and lots of people in the V for Vendetta masks that we have come to associate with the Occupy movement.
The sheer success of the Comic Con underscored the extent to which the whole comic-book phenomenon has become mainstream, that geek is now very chic.
Organisers, while delighted with the public's response and saying they will be back next year, admitted they had under-estimated the numbers of potential attendees.
At midday yesterday, the queues waiting to get into the SECC snaked back to within just a few yards of the Finnieston crane. Even by 3.30pm, the queue was still hundreds of yards long. The last admission into the hall was at 5.30pm.
There were a few gripes on Facebook and Twitter. One man who arrived at 11am wrote that he took 10 minutes to find the end of the "longest queue I've seen in my entire life".
Others, however, registered their approval. "Sitting now, letting my feet rest, been a superb day today!" one fan tweeted. "Really need an extra day for this, it has been underestimated!"
The merchandise stalls were thronged. You could buy everything from comics to Japanese calendars, headbands and confectionery, film cell-sets from movies such as Judge Dredd and The Lone Ranger. One stall sold Spider-Man and Captain Marvel comics. Nearby, a woman told her offspring: "These are old comics from years ago. My brother used to have them."
People queued up to have their photographs taken in Doctor Who's Tardis or in the Back To The Future DeLorean, each for £5 a throw.
A key attraction was the presence of stars such as Warwick Davis, Bruce Boxleitner, Mira Furlan and Hannah Spearritt, who together have been in everything from Star Wars to Torchwood and Babylon 5.
If you wanted a chat and an autograph with one, the price was £15 - the same amount again to get your photograph taken with one of them.
Brian Cooney, co-promoter, said he had no idea of the total attendance but added: "My own guess is easily about 10,000 people, maybe more, which is incredible.
"I under-estimated it, although luckily we didn't seriously under-estimate it. We can handle the numbers. People have had long waits in line if they didn't have advance tickets but we got everybody in and that's the main thing.
"We tried this as an experiment just to see if a one-day event would work. We've already booked for a two-day show next year."
The attractions around him characterised "modern pop culture" - anything that the young adult, and their parents who still think they are cool, want.
"Ninety-three per cent of our visitors in London are under 30; here, it's much more of a family event."
Anime and manga used to be underground but are now mainstream, and there has also been an explosion in superhero movies in recent years.
Asked about the £15 charges for autographs, Cooney said: "They are buying them because they're people they don't normally get to meet." Some autographs - the knights from Merlin, and voice artist Vic Mignona - were free.
"There's always an expense at events like this. If you're bringing over actors from the US you've got flights and hotels," said Cooney.
"A £15 charge is very fair because if they are a real fan, they could buy it from an online site for £50 and it may not even be real."
And the best costume he saw? An "absolutely spectacular" Captain America outfit, from the 1940s.
