Rachel Shianne Williams or "Shi" (pronouned "shy") is Numbuh 86's cousin. Shi is 2 months older than Fanny and her exact opposite, especially seen when they were younger. When younger the two seemed like carbon copies. Shi has curly red hair, emerald eyes, and is small like Fanny. However, Shi is the girly type. Always dressed in skirts, and usually some sort of clip or flower in her hair, or hat on her head. She's always been into Rainbow Monkeys, and often tried to drag her cousin into her games as a child. She hates even the thought of getting dirty and is extremely stubborn and hardheaded. She's also an air head, much to Fanny's annoyance. She works on the Decom. Squad, and her codename is Numbuh 68 (think about that).
