Echidna can grow very large

"Oh. I'm pretty damn sure there's no real connection between her and Endbringers. I saw her at work. Nothing really fit, as far as the various things I saw about Endbringers. No, she's something else."

"Then what does this have to do with her? Because this definitely could have waited."

"Well, there's two major factors at play here," Tattletale said. "Two plans. Numero uno is that it's really quite possible that Echidna's got a broken passenger. Something went wrong, it's damaged, it's demented, or some of the usual limits are gone. Hell, maybe it's gaining more of a grip over her as she brings more of the passenger into this world to operate her body, and the usual processes that keep a passenger passive and sleeping are missing in hers. Or it could be that her passenger is trying to make its way into our world."

"And it's city sized?" Wanton asked. "Or moon sized?"

Tattletale shrugged. "It's not like she couldn't get that big. I was thinking about throwing Rachel's dogs at her until she couldn't support her own weight, but she'd still be able to use her power and puke, and while her clones seem to be getting more fragile, weaker and more plentiful as she grows, I'm not positive that's a good game plan."
