R is the 18th letter in the Alphablock gang. She is voiced by Teresa Gallagher. R is a cherry red Alphablock with upturned black eyes and button nose. She uses scarlet lipstick and wears a black pirate hat with an Alphablock skull symbol on it and a red stripe in its base. She also wears a garnet eyepatch covering her right eye. R is an impulsive, sassy, swashbuckling Alphablock. She loves acting like a pirate. Besides all of this, she's also kinda insecure. The episode Map is a perfect example
