R is the 18th Alphablock in the letter gang.
R is voiced by Lizzie Waterworth.
She is a red block wearing a black hat with a white skull-and-crossbone emblem with an eyepatch over her left eye, as is typical in popular depictions of pirates.
R is a swashbuckling tomboy. She's always saying "arrrr" and "walk the plank" like a stereotypical pirate.
