There are two major story threads in this particular issue, which is set entirely in Noonan's Sleazy Bar. The first involves J'onn J'onnz, The Martian Manhunter willingly, even happily joining Section Eight, thus completing leader Sixpack's designated roster requirements of eight heroes (Well, eight "heroes"). While the parodies of Batman and Green Lantern in the previous issues required them to be written out of character for the sake of the gags, Ennis and McCrea play J'onn almost completely straight. The fact that he's willing to join Section 8, and the fact that Sixpack is still unsure, thinking maybe he should hold out for a "real hero," is parody enough (Although there is a roundabout flatulence gag involving J'onn). Poor, poor J'onn: Screwed over by the New 52-boot and booted out of the Justice League, is this how far he's fallen?
The other thread involves Bueno Excellente, who fights evil with "the power of perversion," and the unseen "suitor" for Guts' affections heard but not seen last issue. Here we see him and, as expected, he ain't pretty. In fact, that whole thread is pretty disgusting, although what exactly transpires between Bueno Excellente and his rival is kept off-panel ("Bueno and this tapeworm guy are having a perve-off," The Grapplah says of their duel). To convey the full horror of it, McCrea only draws the look on J'onn's face when he sees it, and the reaction shot is framed by the most horrible string of sound effects I've ever seen in a comic book (There are 14 in all; two of the least disgusting in this context are probably "Envelop," "Cup" and "Inappropriately Touch").
What J'onn sees is enough to send him hurtling through the roof of Noonan's and up into outer space like a terrified comet.
I hate J'onn's New 52 redesign, particularly since DC seemed to have finally gotten to a pretty good place with him, design-wise, during Brightest Day, and while McCrea draws the new, dumb costume fairly well, he does weird things with J'onn's particularly weird-shaped head (I've never understood DC's need to keep tinkering with the shape of J'onn's head over the last decade or so).
Ennis writes two bravura scenes for McCrea, though. In the first the Justice League and many of their allies discuss the return of Section 8 on their satellite base. There's 18 heroes total, including Justice League Dark and a Doom Patrol (Do they exist in this form?), and there are some pretty fun bits in it. I particularly liked Hal referring to his one-time successor as "Karl Rayner," and Ennis's dialogue for Constantine:
