Wicket W. Warrick
From Multiversal Omnipedia
The Ewok named Wicket W. Warrick found Princess Leia Organa following her speeder bike chase on Endor. A brave warrior for his tiny size (Wicket was small, even for an Ewok), he persuaded the rest of his tribe to aid the Rebels in disabling the Imperial shield generator for the second Death Star.
Expanded Universe
Following the Rebel victory at Endor, Wicket would also help the stranded Mace and Cindel Towani rescue their parents from the evil giant Gorax, and later became Cindel's close friend and guardian following the murder of her parents by Marauders under the command of Terak.
