Re: Fanwankin' Time
Okay, that's Jimenez, Rucka, Johns, and Pfeifer accounted for, leaving Meltzer, Heinberg and the more recent Rucka that Fungo was kind enough to inflict on us all.
The Heinboot stuff you can frame in terms of her struggle with Urzkartaga. Signing on with Circe in light of their past looks insane, but it could easily be desperate instead; if she's losing the fight, well, Circe set her free before, and it's no more dangerous a gamble than with Neron. It even pays off to some extent, if she's able to take on Donna and endure a beatdown from Diana and Herc - that's not up to spec, but it's better than she was in Gotham. It doesn't last, though; maybe Circe just didn't do as thorough a job, maybe the sentient Urzkartaga is a harder thing to disrupt, either way, she's obviously losing again by the time she gets shipped interstellar.
Meltzer is trickier. An off-her-nut, mentally clouded Cheetah signing up with the Society makes sense - her overriding desire was for protection and assistance against ongoing persecution by a powerful enemy, and mistranslating that from "Urzkartaga" to "superheroes" on the way to the conscious brain is totally plausible. But by the Meltzer run of JLA, she seems to be much closer to in control - she's not fully herself but she is smart, together and aware. Did she hope, in accumulating allies, to find someone who'd be more useful than Circe? I'm not totally satisfied with that, but it's closer than just "rar I'm a bad guy I'll join the bad guys."
That leaves us with FC: Resist. Which... it's gotta be an inflicted madness on Urzkartaga's part. Same thing Hera did to Herc when he killed his family. Not a long-term struggle for dominance like the power fluctuation, but a single, furious, petty attack. Minerva doesn't have many weak points, but she does have her dignity - we know she's a very proud creature, who hates to show weakness, loathes owing anybody anything, would die before she admitted affection or allowed a momentary lapse in her sense superiority over all mankind, so what better punishment, what better humiliation than making her debase herself, kittenlike, with a Z-list doofus like Snapper?
Cursed with a momentary fit of playful affection. This would be sufficient motive for arrlaari's contention that she flipped out and ate Urzkartaga somewhere in the recent past.
