Just something I've been wondering...

As I recall from being Dragonfox, the Sentinels could trace "Mutant signatures"

Now, I've already thought about how great Dead Girl would be for sneaking into places. She doesn't have body heat, vital signs, or the need to breathe. Technically, poisons and gases will have no effect on her... yada yada yada.

What I'm wondering is if she would have a mutant signature, given the fact that she's technically dead. If she does not, then the only way to remotely find her would be Cerebro, since she does have a mind to trace, am I correct?

Just wondering, something that been bugging me and I thought someone on here might know.

My opinion - without ever having put too much thought into it before - would be that there is something subtle but distinct in mutant lifesigns (those mysterious whatevers-they-are that all the space shows seem to have sensors to track) that makes a mutant stand out from a typical human. I would think there are at least two explanations (or sources, rather) for that...one tied to metabolism, the other to some kind of brainwave emanation.

That being the case, I would think Dead Girl would be invisible to those kinds of mechanisms that look for metabolic signatures. If something tracked brainwaves - like an EEG - she would probably still be identifiable.

A sample of her DNA could still identify her as a mutant, but that's not to say they could track her with it.
