If you thought that was it for Night Monkey, a great bit of marketing has swung in to prove you wrong.
Spider-Man: Far From Home went down an absolute treat, offering up some much-needed levity after the cataclysmic events of April's Avengers: Endgame.
We join Peter Parker on a globetrotting tour of Europe as his high school trip is hijacked by Nick Fury and the enigmatic Mysterio, excellently portrayed by the one-and-only Jake Gyllenhaal (Prisoners, Nightcrawler).
During the film, to help keep Peter's identity hidden from his friends while he's in Europe, Spidey is given the pseudonym Night Monkey.

How does Spider-Man end up being called Night Monkey?
After having his identity almost discovered by his friends in Spider-Man: Homecoming, Peter Parker is naturally very wary about keeping his anonymity.
Therefore, he gets lent the new stealth suit by Nick Fury, you know, the black one we see in some of the trailers, so that people don't recognise that he's actually Spider-Man despite it being horrendously obvious that he's quite clearly Spider-Man.
In an effort to steer people away from thinking that Spider-Man just happened to end up in Europe, Peter's best friend and man in the chair, Ned, quickly comes up with the name Night Monkey off the top of his head, claiming that this is just a European knock-off version of Spider-Man that he's read about online.
Amazingly, people all across Europe buy the lie and we see some hilarious moments when 'Night Monkey' appears in Berlin and The Netherlands.

Is Night Monkey something from the comics? Where does the name come from?
Despite a lot of Marvel's movies relying on the comics for inspiration, this time that's not the case.
There is no comic version of Spider-Man known as Night Monkey or at least not yet.
It would seem that the name Night Monkey, which is actually a real type of monkey, by the way, is a creation purely for this film.
However, quite strangely, there is indeed a monkey-based Marvel comic book character known as Hit Monkey.
If you imagine Caeser from the Planet of the Apes films and give him a suit, tie, some sunglasses and machine gun, then you've pretty much got yourself Hit Monkey, a killer Macaque with the skills of a master assassin.
Hit Monkey has appeared alongside several Marvel films over the years including both Spider-Man and Deadpool.
However, as far as we're aware, he isn't the inspiration behind the name Night Monkey.
To help the home release of Far From Home - and for reasons we'll get into - they've recently unveiled a trailer for the film, packaged as a movie called The Night Monkey - it's great fun! Give it a watch below:

Update: Will Night Monkey be back in the MCU?
It was reported on August 20th, less than two months since the billion-dollar-grossing Spider-Man: Far From Home hit cinemas, that Sony and Disney have failed to agree on a deal to keep Spider-Man in the MCU.
As a result, a lot of the work that has gone on to put Spider-Man into the galaxy-spanning MCU will have gone to waste.
However, as far as we're aware, the rights of Spider-Man, that Sony seems so keen to hold onto, don't include the European alter ego, Night Monkey
As a result, a number of fans have already been demanding that Disney continue using Spider-Man in the MCU but rename him Night Monkey.
It could even fit into the overarching narrative too with Spider-Man's identity being found out at the end of Far From Home.
But, like all of you out there, we're pinning our hopes on Sony and Disney reaching a workable agreement to keep Spidey in the MCU as he's become an integral part of those films and it would be a travesty to lose him over a silly squabble over the character's film rights.
Come on Sony and Disney, get your acts together and work something out for the good of your devoted fanbase!
