Alycia's thoughts:
The Classic: "Kind of cliche and, to be honest, do we need another overt hero showing off their ostensibly mammalian features? On the other hand, if you're looking to project comfort and safety, the public is already trained by the media for it. Funny story -- after the initial Star Wars movie came out, fire departments reported a significant problem with children hiding from them, as well as the flames, because with their air masks they looked like the movie villain. The opposite reaction should apply here. And there's a reason why cliches become cliches. 'Robots can be heroes, too,' is a good marketing line."
Lady Low-Key: "I do like the sort of confident, don't-mess-with-me air -- you could use some work on that. Helped by you not wearing a mask. [Mutters something to self.]. Actually, it also helps you that everything is either your configurable shell or a holographic projection, so you don't have to worry about 'hey, most of my arms are uncovered so they are more likely to be chopped off." It doesn't exude friendliness, but that could be tweaked to make it lighter, more pop star. Can you sing?"
Lady of Light: "Another basic, almost an extension of the super-suit type. Maybe less approachable, less human-looking, especially if you're talking about someone who is clearly an artificial being -- emphasizing the Other. From a media standpoint, someone the cameras will be trained on for obvious reasons. Certainly easier for fans to draw, which might or might not be a good thing."
Lambda-10.5: "You will clearly have the anime fanboiz all a-flutter, which might not be a bad foundation for a following. This one might be considered scary to some, though, especially if you do the monotone-third-person-I-am-robot routine. That might actually work against your cause, associating robots with, y'know, scary death-and-pain machines. [Raised eyebrow.] From a public relations standpoint, I'd think you'd want a strong meta-story to go along with this, something to help people to see the approachable humanity your projected character is striving for."
"And, of course, there's nothing to say that you have to be just one of these, on consideration. Indeed, coupled with some holographic projectors or even conference call jiggery-pokery, you could seem like a team of your own except to someone really trying to pursue the matter."
