Elastigirl possesses the power to shrink or expand into any size she wishes. She is deeply in love with Niles Cable, and this is shown in both comics of the X-Patrol. Elastigirl was involved in all three missions during the run (though only two were ever published):
- The siege on Latkovia against Dr. Doomsday
- The betrayal of Terra-X (not published)
- An attack on Brother Brood to rescue Niles Cable
Elastigirl was also responsible for putting Terra-X out of action by damaging the traitor's ear-canal from the inside at miniature size.
