Since being transformed into Riftwitch, Rachel has been quite
  pleased with her new svelte figure. She still insists that she has a
  big butt, but so far, no one else has complained. 

  Like her team mates, Rachel can fly, and is able to tolerate
  normal extremes of temperature. In addition, she possesses
  the following abitlities:

  1. She can open up doorways between different points in space, 
  time, and even other realities. This takes some concentration, 
  but she has been practicing.

  2.  Rachel is sensitive to temporal and dimensional anomolies 
  and disruptions. In extreme cases, these can even cause her 
  pain.

  3. She seems to be immune to the effects of paradoxes caused 
  by meddling with time travel. Her existance can't be erased (she
  can certainly be killed, however...), and if she is the one who has
  changed history, she remembers both versions.

  4. Rachel has become somewhat adept at using her rifts for more
  than mere transportaion. She has used them defensively to shunt
  opponents attacks (and sometimes the opponents themselves)
  away from her. Offensively, she has used them to summon all
  manner of projectiles, energy blasts, and the like.
