Croquet, known as Mr. Crocketts in Japanese version, is the right-hand man and butler of Maximillion Pegasus. His duties includes relaying the progress of Pegasus' plans, often unknowingly stating the obvious to his boss (who, with the use of the Millennium Eye and keen intuition, usually predicts the outcome of a situation he's involved with before Croquet can inform him of it). At one point in the English anime translation, Pegasus punishes Croquet for his multiple failures by threatening to "lock him away... again". (Source: Yu-Gi-Oh! Wiki)
