Toni Stark was the friend and traveling partner of Ace Buckley, who built a spaceship that was capable of time travel. Toni accompanied Ace on many trips from their own time in the 20th Century to the distant past. They traveled backward in time to observe a number of important battles and events (such as the Battle of Marathon), and inevitably they were drawn into those events. They met and interacted with a number of legendary historical figures, including Queen Elizabeth I, Blackbeard and King Richard, The Lionheart.
