These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Kaine is this, due to his actions here.He uses his new Spidey suit to cancel out the Queen's sonic scream, and his new stingers to do what Peter Parker never would, and end the Queen's life when Peter manages to weaken her, while declaring to all wondering who he is that "I am Kaine!" And before Madame Web can claim that clearly he was the Spider-Man she foretold would save the world from this threat, Kaine states says everyone that he only could do it wearing a suit Spidey made, using a move Spidey perfected, at a moment that Spider-Man created for him. As far as Kaine is concerned, as well as everyone else, the one who is responsible for the Queen's defeat is the one and only Amazing Spider-Man. And that is how you rescue Kaine from Scrappy status.
And now Kaine's got his own series.
Take That, Scrappy!: infamous Spider-Man Replacement Scrappy, Creator's Pet, Satellite Love Interest, and all around Relationship Sue Carlie Cooper gets this. While at first it seems like more of the same— Carlie gets to sleep with Peter Parker, she gets Spider-Powers while Mary Jane doesn't, and gets to be a "super awesome" fighter to complete the Character Shilling— she then gets her butt handed to her in a fight, turns into a giant spider with the rest of the hapless citizens of New York, and the day ends up saved largely by MJ who gets Spider-Powers without turning into a giant spider. The comic ends with a Peter and MJ Ship Tease of the highest order. On top of that, Peter forgets about Carlie's predicament, leaving her naked and embarrassed in the middle of New York. And then already rejoicing fandom cheered louder when they broke up right after this.
