Heinrich's men made their first appearance in Operation: J.E.W.E.L.S., when they ambushed and surrounded Numbuh 5 in a desert marketplace as Heinrich confiscated the Blurpleberry gem she had in her possession at the time. After 5 scattered her "payment" that Heinrich exchanged for the jewel, she disappeared from his sight into the crowd of children who quickly rushed for the candy. Heinrich then ordered his soldiers to search the marketplace for his rival, demanding that he see her in chains by the time of his return before driving away in his tank, not knowing that 5 had secretly stowed aboard.
