Croquet
Mr. Croquet, known in the Japanese version as Mr. Crocketts (Mr. クロケッツ Kurokettsu), is the right-hand man of Maximillion Pegasus (Pegasus J. Crawford in the original Japanese). 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', which leaves one to speculate whether or not Croquet had also experienced his soul being trapped in a card by Pegasus, or if he was the victim of another form of confinement altogether.
Croquet reappears in Yu-Gi-Oh R, though he 'vanishes' after Yugi defeats Gekkou Tenma.
