I'd like to think the reactions of other heroes would vary wildly.  I think many would just see her as another hero, while some might consider her from a period too far gone to really serve the role of a hero.  Still others might think her to be dangerous and a risk due to the possibility of the time shift overwhelming her.  I think some might even be against her because of the danger of her following the same path as her future self did, and not wanting to take that risk at all.<br/><br/>I think the government would see her as some kind of an anomaly, but one that they could learn from.  If you have some woman that can travel through time, from the Old West to present day, the first thought must be "Can we find a way to use that to our advantage/as a weapon?".  And if that's the case, they'd have to speak to her or arrange some kind of meeting directly.  I also think Zylphia would be untrustworthy of the government people due to them being...well, creepy.  That, and she wants to minimize the potential leads her future self has to find her, so she'd probably try avoiding the government or shutting them down each and every time.<br/><br/>EDIT:  I could also maybe see there being some benevolent government people who might want to help her adjust to the times.  Maybe they'd give her shiny new guns!
