Neogenic Nightmare Chapter 8: Duel of the Hunters - S2-E8
Other mistake: After falling down the cliff and getting blasted back by his van's explosion, the Punisher shows no signs of injury. This kind of fall combined with explosion should have killed him, or at least injure him very severely, as he is a normal human without any superpowers.
Sins of the Fathers Chapter 1: Doctor Strange - S3-E1
Revealing mistake: When Mary Jane and the other servants of Baron Mordo are flying through the city, they literally disappear into thin air. Probably a problem with rendering the 2D animation within the 3D animation. (00:01:00)
Spider-Man: Subtetly is not your strong point, is it?
Wolverine: Hey, can't even spell the word.
Sins of the Fathers Chapter 9: Tombstone - S3-E9
Trivia: When Spider-Man saves Tombstone from falling into a bubbling vat he jokes about him coming out with "green hair." Clearly that's a joke referencing DC comics' Joker.
Question: Was the script for the sixth season written before this show was cancelled?
Answer: Yes. Many things that would have been in the sixth season would have had Norman Osborne returning from limbo and reclaiming the title of the Green Goblin, Richard Fisk, the son of "The Kingpin" Wilson Fisk would return as a crime lord known as "The Rose", Ghost Rider would have appeared to help Spider-Man stop Dormammu from returning to Earth and Madame Web and Spider-Man would rescue Mary Jane from limbo.
