Karen Peterson was Jack and Janice Jordan's next door neighbor and babysitter.

When Hal Jordan moved in with his cousins, Karen quickly discovered Hal's double identity as Air Wave but kept this information secret, even from Hal.[1] She later sewed a new costume for Air Wave when his was destroyed by his cousins Jason and Jennifer.[2] Hal and Karen later started dating and Karen showed some jealousy when Hal's football skills brought him to the attention of an older, popular girl.[3] Once, she helped jog Hal's memory when a villain gave him amnesia by wearing a duplicate of the villain's costume, all without revealing she knew his secret.[4]


  • Although this character was originally introduced during DC's Earth-One era of publication, their existence following the events of the 1985–86 limited series Crisis on Infinite Earths remains intact. However, some elements of the character's Pre-Crisis history may have been altered or removed for Post-Crisis New Earth continuity, and should be considered apocryphal.
