Horologium (ホロロギウム Hororogiumu?) is an anthropomorphic grandfather clock large enough for up to three people to fit within his chest cavity. He is typically summoned by Lucy to use for shelter or transportation, and can summon himself to defend her or her friends from dangerous attacks. Once someone is inside, Horologium repeats everything he or she says, even when no one else is around to hear it. He is voiced by Masaki Kawanabe in Japanese and Ben Bryant in English.
