Hmm, Fire Blast d12 is roughly the same level of power as a nuke, Fire Supremacy d12 can create effects large enough to extend over a small country and Fire Resistance d12 is a near-immunity to fire-based attacks...  Ace would say yes right away to letting her join, but of course Darclight is the one making the final call on that sort of thing. :P<br/><br/>A couple of the SFX on your power-sets need minor corrections on mechanical terms, but otherwise they look good. Supernova on the first powerset should say Physical Stress, rather than Physical Damage, and if it's based on the Human Torch's similar SFX, it should probably trigger on each subsequent Action or Reaction, rather than just on your actions. Meanwhile, the Heals up real nice SFX on the second powerset still says to spend doom dice, rather than plot points. Also, if the idea on that second one is that she's been upgraded from having good stamina to having full-on regeneration, it might also be a good idea to take the text from other healing SFX about letting a plot point step back Physical Trauma, in addition to getting rid of Physical Stress.<br/><br/>The Milestones need a bit more work. A better 3 XP option for The New Hotness might be one that triggers when you get taken out by your own Supernova SFX in a fight, for example, since the 3 XP rewards can only be triggered once per scene. 10 XP rewards can be triggered once per event, and should have a bit of a choice to them, since they're generally supposed to reflect the end of a major story arc for a character. So, for example, the Millennials 10 XP trigger could be 'When you finally decide to become an adult and take shit seriously, or your refusal to do so leads to a major disaster.'<br/><br/>Aside from those small issues, Sofiya's character sheet looks pretty good to me.
