Instead, he travels to the Homelands by himself to strike at the Adversary's heart and kill lots of Goblin butt.
Do you see the two things he's holding right there?
The blue cloak is enchanted, and it's called the Witching Cloak. It's pretty much impenetrable, and it lets Boy Blue turn into any animal he desires!
(Yes, he does turn into a bluebird for one page.)
And I think you can guess what sword he's holding: it's the Vorpal Blade from the poem "Jabberwocky!"
I may be speaking for myself, but that's the coolest literary reference I've ever read.
Scan taken from Fables vol. 6: Homelands. Not only is there a straight-up classically-written adventure story, there's also a hollywood fame story and a one-shot of one fable's return to Fabletown.
