Insomniac's debut into the superhero genre with Marvel's Spider-Man on the PS4 was a treat, feeling like Dan Slott's iconic run brought to life, with fan-service galore, whether that be easter eggs or in the inclusion of lesser-known characters like Yuri and Morbius.

As such, with a gigantic roster of characters to play with, Insomniac has a lot of wiggle room in the future direction. However, they already made a fair few changes from the source material as is, so here are ten things that you may not have known about some of the side characters in Marvel's Spider-Man.

10 Yuri Watanabe Became A Vigilante Called Wraith

Yuri may have gone rogue in the DLC for Marvel's Spider-Man, working outside the books to a degree, losing herself in a vendetta, but in the source material, she does so in a much more comic-book fashion.

Instead of simply going off book and hunting down criminals in her spare time, she dons a costume and a new alias - Wraith. She comes head-to-head with Spider-Man numerous times but, for a while, he begrudgingly works with her, knowing her true identity, but Yuri's grasp begins to slip as she loses herself in the chase.

9 Tombstone Went To High School With Robbie Robertson

Tombstone is somewhat unrecognizable in Marvel's Spider-Man as the team opted for a more grounded appearance as opposed to his Frankenstein-look of the comics with his hilariously square head.

When introduced, he was intrinsically tied to the Daily Bugle and, in particular, JJJ's right-hand man, Robbie Robertson. The two went to high school together and, once they grew up, Robbie knew of Tombstone's nefarious life of criminality, but he stayed quiet until Tombstone returned to New York City out of fear for his family's safety.

8 MJ Rejected Peter's First Marriage Proposal

Peter Parker and Mary Jane Watson's marriage is a moment as iconic as Gwen Stacy's death and their long-standing relationship would cultivate in disappointment with One More Day, leaving them aimless for a time.

However, things weren't all roses and daisies in the beginning, as Mary Jane Watson, at first, declined Peter's marriage proposal. Eventually, the two did hit it off and decided to settle down together, or at least as much as a vigilante like Spider-Man can.

7 Black Cat Has Bad Luck Powers

By some stroke of genius, the brains behind Deadpool 2 managed to make Domino's luck-based power-set work on the big screen in a captivating manner, but she isn't the only heroine to have these abilities.

The criminal turned anti-hero turned villain turned anti-hero got her powers from the Kingpin. In a test, she was bestowed with powers, meaning that those who faced her would have incredibly bad luck which was fitting given her name. This often allowed for her to get out of sticky situations that she would've otherwise likely failed in.

6 Norman Osborn Had An Affair With Gwen Stacy

In an incredibly controversial twist retcon, it was revealed that Gwen Stacy had an affair with Norman Osborn back before he killed her in the iconic run from Gerry Conway.

This twist came at the behest of the introduction of two new characters, Sarah and Gabriel, who were later revealed to be the offspring of Norman Osborn and Gwen Stacy. It'll be entirely understandable if Insomniac gloss over this little tidbit of Spider-Man mythology.

5 Aunt May Married J. Jonah Jameson's Father

Aunt May not only had a fling with Doctor Octavius, otherwise known as Doctor Octopus, arguably one of Peter's most iconic antagonists, but she also dated and married the father of hot-headed publisher James Jonah Jameson.

This, inadvertently, made Peter and JJJ step-brothers, which could make for one helluva parody of Will Ferrel's film, but for now, it remains a hilarious point of contention stock full of gags and awkward family dinners left in the history of Spider-Man's comic run.

4 Jefferson Davis Was An Undercover Agent Of S.H.I.E.L.D. In His Youth

Jefferson Davis, otherwise known as Miles Morales' father, is a police officer with a sketchy past that he kept from his son, but eventually, in Bendis' Ultimate Spider-Man run, the truth is revealed.

Whilst Miles' uncle, the Prowler, was a criminal with a known past of wrongdoing, his father was an undercover agent working for Nick Fury, helping to take down Kingpin and various other criminals. He gave up this life and opted to become a policeman instead, believing it wasn't for him.

3 Miles Morales Wasn't Excited About Getting Powers

In Marvel's Spider-Man, Miles seems incredibly eager to get into the swing of things when he has his powers, begging Spider-Man to let him come out with him on patrol. He's a little more cheery to have powers than his comics counterpart.

In the comics, Miles gets his powers just before the death of Spider-Man, like in Into The Spider-Verse, but he didn't want to use them, seeing them more as a burden than a gift. When Peter died, this was reinforced and, eventually, he gave up the webs for a year. It took some doing to pull Miles into the vigilante game.

2 Morbius Was A Member Of The Midnight Sons

Morbius is seen for an incredibly brief time in Marvel's Spider-Man and he is not the Living Vampire, at least not yet. He's your average doctor and if it wasn't for the name, he could be just about anybody.

However, he shares the namesake of a character in the comics who has a rich history with Spider-Man, but he also stood out on his own for a while such as when he became an anti-hero and joined the Midnight Sons alongside Hellstroma wealth of others such as Doctor Strange and Blade.

1 Kingpin Once Hired Electro As A Henchman

The 1610 universe birthed Miles Morales following Peter's death, but way back in Parker's infancy when he was just starting out, he came head-to-head with the Kingpin who, at the time, had hired none other than Electro as muscle.

In a funny twist that irks Max Dillon, Kingpin refers to him as another character, Elektra, before unleashing him on the amateur wallcrawler with a death wish. It's a fairly brutal fight that shows Peter's vulnerability quite well.
