At least the nanites I was handing out were thoroughly limited to healing, and there was only so far that regeneration could be weaponized.
Taylor weaponizing self healing:
"She triggered that bomb and went through f*cking black hole the bomb generated without missing a beat," Assault exclaimed during debriefing "reformed out of her bugs then fell apart to pass the cage Bakuda built around her magnum opus, reformed again and then cut that device by apparently using atomically sharp spider webs under a form of telekinesis. Guys, I don't know about you, but I'm considering transferring out of here."
"You forgot to mention that Everyone present sans Undersiders opened a brick factory when they saw her," Battery shuddered "and that unsettling pitch black carapace of hers enhanced the effect. She is Terrifying when she wants to be."
"Gives whole another meaning to a 'biblical plague'," agreed Triumph "because turns out a plague with intelligence behind it is another beast entirely." Then he addressed Armsmaster and Miss Militia "Are we certain she wasn't playing mind games with us and all that actually happened?"
"If she is playing mind games, then she fooled even my equipment." answered Armsmaster without looking away from his laptop "My sensors indicate that she was indeed there. And I can say that she did miss a beat while going through that blackhole."
"We need to think of containment measures just in case we come to blows." Sighted out Miss Militia "She can fall apart into her swarm and reform short distance away to pass obstacles like metal bars, normal physical restraintment won't work. We will need some way to sedate her. But if black hole didn't stick, normal chemicals likely won't either. At least not when directed at her.... But may be we can use pesticides to make her bugs lethargic? Normal foam wouldn't work either, may be we can get some modified foam, more gel-like with wider reach and stronger adhesive properties to have her 'glued'? Bugs can be very small, so any cell will need to be fully sealed at a minimum."
"I think you are missing the elephant in the room." noted at that Velocity "She is getting stronger and Fast! If she can do this much now, she likely will be able to 'teleport' by reforming elsewhere by the time we set such a cell. Assuming she won't just slice such a cell apart by magically manifesting supernaturally sharp spider webs. Those bars were bobby trapped, which might be why she didn't slice them."
