Keyloid

Keyloid (キーロイド Kīroido?): Keyloid, designated O-69, is created when the Tojiru (閉じる?, "to shut close") Metavirus infects a motorcycle key. The multi-dimple key on his right arm can lock anything, door or object. Keyloid is created in order to trap humans in the Ariadne Building as part of Escape's scheme to cause human suffering. Once the plan is derailed, Keyloid is destroyed by Blue Buster, Beet Buster, and Stag Buster.

Keyloid is later recreated by Messiah.
