Vea

Vea was the Terugan companion of, who appeared to be, Yon from the "31st century" (???). The two travelled around in a magical cardboard box that was "smaller on the inside" alongside a robot nicknamed D-J.

Once, they landed the box on a planet home to beings they thought they could trade with. Instead, they ended up angering them somehow, and running for their lives back to the box as the aliens started shooting at them with laser rifles. Once inside the box, she pulled a lever and materialized on the BZP Planet which was, at that time, outside the multiverse. As far as we know they're still there.
