She spits a foam that corrodes stuff.
This is a great action scene for the lovely little girl. Jane looks as fierce and strong as she is pretty, and even without her powers I bet she could get in a few good licks (or more like bites and scratches, but maybe just enough). Beautiful work on the girl, very nice form and lovely chubby face, though the rest of her body looks nice and strong – even what's just hinted at under her lovely blue raincoat, which compliments her eyes and even her hair nicely too. Her fists make some beautiful emphasis too.
Jane is kick-ass with style. Thanks to you and Viceform for sharing.
