Robbi Rodriguez's Spider-Gwen costume design was a hit with fans shortly after being introduced to the world last year, but at least one person wasn't quite satisfied at first glimpse: "Amazing Spider-Man" writer Dan Slott, who sparked the idea of a spider-powered Gwen Stacy appearing in the recently concluded "Spider-Verse" story.

"I described the Gwen Stacy costume in the old 'Superior Spider-Man' plot," Slott shared in an interview with CBR published earlier today. "The costume was very specific -- and it was just good luck that no one sent that to the 'Edge of Spider-Verse' team, so they came up with their own thing.

"In my head, I lived with this character for a year, and the visual I had for her was pretty much 'The Night Gwen Stacy Died' outfit, but all red and blue with web patterns and a half mask," Slott continued. "So you look at it and go, 'Hey! It's Gwen as Spider-Girl.' She had the trench coat, but instead of it being lime green, it'd be red with webs."

Though the now-famous look that the "Spider-Gwen" team of Rodriguez and writer Jason Latour wasn't what Slott originally had in mind, he admitted he's happy that things went the way they did.

"I so wanted that -- and since that was the character that was in my head, and even though these great designs came in, I was like, 'That's not Spider-Gwen!'" Slott said. "I was the one guy going, 'They have to change it!' Then I got to see what they were doing and I was so glad no one listened to me. [Laughs] Because this character is awesome! It's so much better. So that was some really great alchemy -- and luck."

In the same interview, Slott also disclosed that the creation of Spider-Punk was something of a happy accident.

"["Spider-Verse" artist Olivier Coipel] came up with the design we now know as Spider-Punk," Slott related. "He said, 'That's Spider UK.' I said, 'That's not Spider UK. He's supposed to be from the Captain Britain Corps. He should have the Union Jack and the Spider. This guy's all punk.' He was like, 'Yeah! It's all punk, and very London!'

"Olivier was bummed, because the Spider-Punk design was brilliant," Slott continued. "So I said, 'That's a great design! We will totally use it. We're creating all these new Spider-Men. So when we get to Doc Ock's army we'll put him there. He'll be one of Doc Ock's best henchmen and he'll be there all the time! We'll show you Spider-Punk non-stop! I promise you!'"

As a result, Spider-Punk has already extended beyond comic books -- he's a character in the "Spider-Man Unlimited" mobile game. Slott also discussed the end of "Spider-Verse," the fallout of that story and more, in in CBR's full interview with the longtime Spidey writer.
