Thanks for the advice! :) Mostly I'm just new to the RPing format on this site. But I'm fairly well versed in the Marvel EU, and I have a mutant character that's been sitting on the sidelines of my brain for a while, so with a few tweaks she'll probably be power based on Magma (Amara Juliana Olivians Aquilla) from the X-Men. Also, while the name Magma is kinda cool, am I allowed to change it?

Absolutely. Just tell us who you are using for a basis so we an cross them off the list of taken characters. Magma is an excellent choice.
