Ewing’s script for “Mighty Avengers” #1 was inadvertently leaked by Marvel, posted online with the intent of helping to create portfolio review sample art for Festo Comic Con (via Bleeding Cool) reveals the full identity of the character in the Spider Hero costume as Blade, Marvel’s resident vampire hunter.
According to the script, he is the silhouette figure during a conversation with Monica Rambeau. Blade’s appearance in “Mighty Avengers” seems to signal the resurgence of vampires in the Marvel Universe. Last we saw of any vampires or Blade was during the X-Men event “Curse of The Mutants”.
There’s a silhouette in the doorway, leaning out — BLADE’S. The reason I want to do it this way is so as not to let the readers know who this is until further down the line. So we hide Blade’s identity this way, and tell it in Monica’s reaction — he’s someone she knows or has heard of, and she’s a little surprised to see him here, but she knows what it means if he shows up: vampires. Blade explains that he needs her help.
The script goes on to confirm the character’s identity during his first appearance as Spider-Hero.
Enter Blade, in the SPIDER HERO suit. This is basically a spandex, old-style spider-man costume, in a hideous combination of neon pink and neon green with SPIDER HERO written across the chest in place of the spider logo. It’s incredibly cheap looking. He’s going to be wearing this at least until issue #4, when probably he’ll change into the Ronin outfit.
