Jack-in-the-box Shadow is a Shadow Creep in service to Grita armed with the Cuckoo Clock Door (鳩時計系ドア Hatodokei-kei Doa) from which he can fire an energy beam and the Juggling Clubs (ジャグリング系棍棒 Jaguringu-kei Konbō) as hand-held weapons. He is sent out by her to gather darkness on behalf of General Schwartz. He delights in using his wacky illusions to make people laugh, as, anyone who laughs in his presence will then be sprung into the air, thereby creating "a hell of laughter." Anyone in his presence who laughs is subject to this, even other Shadow Line members, like Grita, and himself.
Jack-in-the-box Shadow would then be brought back as a ghost, or rather, a copy by Tombstone Shadow, alongside Fence Shadow and Pin Spot Shadow to back him up in his giant battle against the ToQgers. He was destroyed again by Diesel-Oh's Diesel Missiles.
