In Unplugged, they create a massive electromagnetic frequency generator and wiped out all the electricity in London, and caused planes (including Thunderbird 2) to fall from the sky. Lady Penelope and Parker disguised themselves as members, and discovered they were stealing a device called the Universal Grid Codex to destroy the Global National Grid.

The Hood, who was disguised as one of the members, escaped with what he thought was the Codex, but it turned out that Parker switched it with a torch.
