Adapts to Crawler's acid, grows plates

He spat at her, and the acid sizzled as it hit her. However, a moment later, her sizzling flesh regenerated, along with her clothes. He spat at her again, but the acid was simply absorbed into her body, leaving her dry and unbothered.

"I want you to guess what I stole from you," she said. "You aren't that bright, but I'm willing to give you a few tries."

He bit down and chewed on her, and this time she seemed a little more rubbery than she had been before. She appeared again, and he ate her again. This time it was like like trying to chew on hard rubber. He gagged a little and he vomited her back up.

She stood up, and plates were forming on her body.

"That won't do," she said, looking down at herself. "I don't want to look like a freak after all."

A moment later the plates shimmered, and looked like flesh. When he surged forward, though, smashing her into a wall, her body still felt hard, and when she got up, she smiled.

"I'm glad you're an idiot," she said. "I can see why you liked this."

What?

"What do you mean liked?"
