In John Smith 10, Four Arms wears gold wrist and ankle bands, as well as two golden sashes that go across his chest. He appears as he did in the Ben 10-Generator Rex crossover, with black pants and fingerless gloves.
In Jane Smith 10, she wears a pink and black outfit similar to the Omniverse design, with pink eyes. The Omnitrix is on her belt. She doesn't have facial hair.
In Argit 10, he has an Omniverse appearance. The hair on the back of his head is spiked up, and his suit is orange and black.
