In the late 1100s, thirteen-year-old Will, the future Lord of Shackley, is exiled to Sherwood Forest, where he meets Robin Hood and the Merry Men and bands with them to try retake Shackley Castle.

With the Normans threatening to overrun Wales, forester Will Scarlet is being sentenced to die for a crime he didn't commit unless he betrays King Raven and his followers, and Bran ap Brychan makes a secret voyage to France to uncover a plot against the king.

It's the year 2167 and twelve-year-old genius Robin Hood has invented time traveling technology, but his bosses only want to use it to monitor the timeline and make sure everything stays the same. Robin wants to help people (and luckless dinosaurs), so he uses his device to travel back in time, picking up some other do-gooders along the way and being pursued by his heartless boss, Mr. Prince.
