Kari Lai is the younger twin sister of Mari Lai and part of the duo of Sword and Shield.
Kari is by far the more reserved and quiet sibling, and would likely not have even taken up a career in crimefighting had her more outgoing sister not needed her by her side for their powers to work properly. After much convincing, Kari agreed to help her sister out in her battle against crime and took up the name of “Shield,”, serving as a human wall to protect the innocent from harm.
In her social life, she is the lover of Megan Plainsmith, the former Cyber Grrl, and convinced her to join them as their adviser, gadget-provider, and behind-the-scenes manager. She also serves as a calm, rationale counter to her more hot-heated sister and a kind and soothing voice of reason in their partnership.
Shield shares a special physiological and mental bond with her twin sister. The two have the capacity to share thoughts, emotions, and stimuli instantaneously, though it is a process neither has much control over. This unfortunately has led Kari to experience some of the same pleasurable sensations Mari feels when she is with a lover, which can manifest itself at inopportune times.
More importantly, Sword and Shield share a bond that allows Shield to absorb kinetic energy and channel the power into Sword, making Shield nearly impenetrable and turning Sword into a blunt instrument of offensive power.
