I take it instead of atomic fire breath, she fires atomic mutation breath that turns people into more Cheshzillas?

*chesh's car-sized head crashes thru your wall and stops inches from your face- glowing eyes wide in disbelief*
"Tell me more of this atomic mutaion breath and were I can get it!!" :o

-looks at the bus sized window right next to that spot- First, there was a window right there, Miss Kool-Aid. Secondly, I thought you already had it. -brazenly steals a kiss from the fellow kaiju- Anyways, I suspect you breathe the usual glowy greenish blue fire, but rather than burning people it turns them into miniature lizard cat things with oversized boobs. About a day or so later they're just as big as you and firing their beams at others and spreading further. Just a theory anyways. Have to find some normal humans and furs to test it on. I hear Janus should be getting off work about now.

I like to imagine that despite being a terrifying kaiju she's still Chesh and somehow harmless...well, as harmless as Chesh usually is anyway XD

SHe's using that as a scratching post isn't she?

Must be QUITE the view for the occupants of that building! ;3
