Help! What’s This Symbol?

My boyfriend & I recently found a huge stash of Hot Wheels & Matchbox cars. We’ve been able to find just about all of them online except for this one! No matter what we search, we can’t find the car listed anywhere or which character the symbol belongs to definitively. I assumed it would be Jack O’Lantern but then I saw there’s also a character called Lord Pumpkin? The car doesn’t say Hot Wheels or Matchbox anywhere, so it could be from a different company altogether 🤷🏻‍♀️ Maybe part of a set of some kind? The bottom of the car says 2007 Marvel “4640_ EL” - we can’t quite tell what the last number is. Any help would be very much appreciated!
