Re: Back to Normal ?
Anthem would have to leave home. Her father is an abusive drunk and what's kept her out of harm thus far has been her invulnerability. She's not one to take handouts so she'd likely become homeless for a while, but she'd make contact with other heroes to see if they can help her unravel her dilema (meanwhile keeping secret the fact that she's homeless).
Uncle Slam would presume this is like the time back in '68 when ZeroSapien took his powers and implanted them in one of his mindless husks (think of The Mad Thinker's Awesome Adroids). Back then he had to defeat the husk and upon rendering it lifeless the powers came back to him. It was only that the husks are so stupid that he defeated it without his powers. He'd check on the wereabouts of ZeroSapien (Last he heard the villain had reverted to a pool of ooze and been washed away in a storm drain back in '70, never to be seen again). Meanwhile he'd contact PRIMUS to see what they can do about hooking him up with a few gadgets for his exploration, and also so that he can give the outward appearance to normals that he's still powered; after all, the ultimate power of Uncle Slam is the confidence and security he instills.
Audra Blue is partly cybernetic. If she woke up without in implants she'd have a mix of fear and relief. She'd never have to take the chemicals that keep her from rejecting the implants, but she'd feel utterly vulnerable. To do her job on the 'net she'd have to go turtle (connect to the net with electrodes rather than jacking in, which would slow her down considerably). She needs to connect to the network for her sanity, but once there she'd be a target for anyone who figured out that she's not as tough as she once was. As for figuring out what happened, everything in the base is recorded. She'd go back over all records, checking redundant backups if necessary, and the secret backups of those backups.
