Oh, geeze. I just picked a person/name and an ability I've been wanting to try out. I'm not much of a comic person so I don't know anything about the (lesser) superheroes/X-Men but I certainly wasn't trying to make a Dust Clone and I tried avoiding doing so.
Also, yeah I was having trouble deciding between outright Sand Manip and Sand Mimicry. I really like the length of these powers. I didn't know how much to include in my mutation section since I only read a little (at that point), but I think the development of her powers could go places (if accepted).
Anyway, thanks for the further information and I'm excited for the results.
Howdy. Just wanted to fire you a couple of links relating to your X-Men SU. I'm sure you've done your research on Sand Manipulation, but just in case, here are a few characters with similair abilities. The Powers and Abilities sections are where I'd recommend checking out;
http://en.wikipedia.org/wiki/Dust_(comics) (I had concerns when I saw your characters name and mutation, before you finished your SU, that I was going to see a Dust clone. Really, really happy that this wasn't the case.)
If you need anything from me don't hesitate to ask. Sign-up results will be posted at the start of next week.
