Shouted reply, "I am not a villain!" She twists around in the air and her favorite hammer goes Whack! She deliberately tries to expect it to send Glam flying in the correct direction and not actually hurt them.
Now, where is she?
If Glam doesn't move rocks and rubble are going to hit them like a wave.
Well, Glam has apparently gained the ability of teleporting! Or something like that, anyway, since they vanish from the way of the rubble right before their turret shoots a ball of hardened wind at Mountain.
The turret no longer has ground to stand on. And also has a hammer coming at it.
And there's another ball of hard air coming from over there, and yet another one from that other direction, and Glam seems to be teleporting here and there to shoot.
She feels at the holes in the world to get a sense of their location and number. Any turrets on rubble that's not too close to non-rubble get the same treatment as the one before, and she keeps trying to hit the teleporting Glam.
One Glam who has conjured a large ball of diamond with the Mountain-blocking energy field around it and has hurled it at her at a very high speed.
Giant hammer meets ball of diamond: Return to sender. She still has control over her own armor and the giant hammer, so the shock of the impact isn't too severe.
And now there are more turrets shooting more balls like those, from various directions simultaneously.
(And of course, if one appeared right behind her at a moment Glam believed her distracted, that is entirely intentional.)
While dodging, of course. And let's have a very localized earthquake, just to help them along.
That breaks their stride. Only for a second, though; the turrets are entirely optional, it can just rain directed diamond at her from the sky, trying to shoot her to the ground.
Mountain mutters something about needing sensors while fighting to stay in the air.
Glam eventually notices that it's stopping stopping her, and decides to be even more creative: encasing the diamond in plastic.
The rock armor suddenly grows to about fifteen feet tall and starts resisting plasticdiamond by sheer size. She tries to distract Glam from their diamond rain by making large sections of rock and rubble crack simultaneously in a rather loud CR-CRUNCH.
Shifting rock around so much generates a lot of heat when she's not paying attention to making it not do that. Parts of her armor especially around the joints start to glow a dull red.
Glam can beat this if she doesn't interfere. It'll be easy, even.
Uh. Glam? I was about to lose.
Alright. Cleanup time, then. She fans her newly huge armor into long thin plates to bleed off some heat, then pushes it into the ground, then starts working on the rubble.
But okay, she can roll with it. "Gah, I thought we were done! How am I supposed to beat 'impossible to hit and makes stuff out of thin air' anyway?"
How hasn't she called the PRT yet? She calls them and reports imminent defeat by Glam at such and such a place.
"Fine! You win! But I could beat you if I didn't have to hold back 'cause this is the middle of a city!" And then she lands and holds her hands up. "Just let me get back to fixing this place up and try not to give me more work, okay?"
The rubble is in a slightly different configuration now, but overall this was a sufficiently flashy fight with no collateral damage.
She starts putting up a building.
Glam sees a PRT van in the distance from their vantage points and decides to say 'bye.
Back to building, building, building. Some of the rubble is still glowing red-hot, so she dips it into the river before using it as structural elements.
