Catherine Elle Armstrong

Catherine Elle Armstrong is the fourth daughter of the illustrious Armstrong family and the youngest sister of Major Alex Louis Armstrong and Major General Olivia Milla Armstrong. Her girlish good looks and stunning figure bely an inherited strength that allows her to lift objects like pianos above her head. Catherine is shy by nature, but has stated that she prefers the company of men who are as muscular and strong as her elder brother.

Catherine first appears in the Manga Gaiden Chapter "The Second Lieutenant Goes to Battle" (which is later adapted into Episode 37 of the 2003 anime series) in which she is formally introduced to 2nd Lt. Jean Havoc, who has been forced to end a budding relationship in East City upon being transferred to Central City. Despite Havoc's initial fears regarding Catherine's family bloodline, he finds himself attracted to her and the two appear to get along well. But when Jean asks Catherine out directly, she apologizes and says that she only dates muscular men. Catherine appears again in Chapter 83 when Olivia demands that her father leave the Armstrong mansion to her and immediately vacate, which - understanding that his daughter is warning him of some impending danger - he does, leaving for Xing with his wife and youngest daughter. As Olivia and Alex combat over the right to the house, Catherine kindly offers wishes of good luck to Alex, suggesting that she may prefer her brother to her eldest sister.
