Flan's Box Weapon appears as a miniature version of Flan's fellow Varia member, Belphegor, surrounded by Mist Flames and attached to a spring, making it look like a jack-in-the-box. Its Flames were later absorbed by Ghost, thus destroying it. Apparently, for comedic effect, the miniature's face contorted into a pained expression when it was struck by one of Ghost's energy tendrils.
