In Marvel, it really isn't all that uncommon to see heroes fighting villains who debuted elsewhere and are more associated with others. Really, it seems less of a hard rule that this villain must antagonize this hero, and more of a suggestion.
Examples:
- Klaw is a Black Panther villain, but has fought the Fantastic Four and Daredevil.
- Boomerang debuted as a Hulk villain but quickly moved to Spider-Man due to how bad of a fit he was for the character.
- One of Spider-Man's famous '80s stories had him fighting the Juggernaut, normally an X-Men villain.
- Sabretooth is the archenemy of Wolverine, but originated from Iron Fist.
- Doctor Doom is commonly thought a Fantastic Four villain, but has really menaced every big hero including the Avengers, Iron Man, the X-Men, Thor, Hulk, Spider-Man, Doctor Strange and Black Panther, among others.
- Kingpin was a minor Spider-Man villain but is now Daredevil's archenemy. DD has also fought Electro and Mysterio in the past.
- Sandman debuted in Spider-Man but spent a large amount of time fighting the Fantastic Four.
- Magneto has fought the Avengers, Spider-Man and Thor even though he's the X-Men's most famous nemesis.
- M.O.D.O.K. was created to be an enemy of Captain America, but also menaced Iron Man, Carol Danvers and Hulk as well as the Avengers.
- Mystique was originally Ms. Marvel / Carol Danvers' nemesis, but migrated to the X-books.
- Recently, Kamala Khan inherited Shocker from Spider-Man.
- Ultron was a longtime exclusive villain of the Avengers, but was the main villain of Annihilation: Conquest (focused on cosmic heroes), and Age of Ultron where he fought everyone.
- Norman Osborn / The Green Goblin was an exclusive villain to Spider-Man for a long time, but that changed in the '00s when he became a general MU big bad and menaced just about everyone both directly and indirectly.
And these are just some examples off the top of my head.
Overall, it seems Marvel is much more flexible with the idea of heroes fighting other people's villains than DC. In DC, I honestly have a hard time naming such instances of heroes and villains of different origins fighting each other outside of big crossovers. The best I can think of is Deathstroke originating in Teen Titans, and menacing them, the various Titans teams, Batman, Nightwing independently, and Green Arrow. Few other characters seem as versatile in DC.
Apparently, it's also part of the creative process:
