A member of the
Mutant Liberation Front, Thumbelina loyally served
Stryfe and was often seen at his side. Her mutant ability to shrink her body made her a valuable asset to the group, and allowed for her to participate in missions requiring espionage. However, she was much less ruthless than her cohorts, and was often teased by the other members for her weight. She is also very close to her brother
Slab, a member of the
Nasty Boys. When the
X-Men raided the Mutant Liberation Front's headquarters, Thumbelina and Slab were frozen and defeated by
Iceman, apparently taken into custody.
Much later, Thumbelina resurfaced, following orders from an alternate version of
Domino who had taken the guise of
Stryfe.
