Paper-Thin Disguise/Fan Works

Examples of in  include:


 * A large degree of Kirby fanfiction gives Kirby the ability to become completely indistinguishable from whoever he's taken the power/costume of, despite the obvious size differences.
 * Kyon manages to call Tsuruya and make her think he was his uncle Kintaro in Kyon: Big Damn Hero, even though he sounded identical to normal. He was sleeping in the same room as her at that point, though.
 * The incredibly useless Invisibility Cloak in My Immortal: people can see the cloak when it is in use, so basically the users are walking around with a regular cloak over their heads.
 * According to Light and Dark The Adventures of Dark Yagami, a naked woman can pass for a man merely by having a tattoo that reads "IM A DUDE".
 * In the Calvin at Camp episode "The New Kid," Larry Koopa infiltrates the camp while wearing nothing but a Mickey Mouse hat.
