The Three Beckys are three girls who used to bully Lettuce Midorikawa. They pretended they were her friends so they could spend her money and get her to do their homework for them, and Lettuce is convinced that these girls will be the only friends she'll ever have because she is so shy (that is, before she meets Ichigo Momomiya, Mint Aizawa, and the other Tokyo Mew Mew). The girls are seen to be spiteful and bossy. They go to the same school as her (Okumura Junior High School, called Excalibur High School in Mew Mew Power), and are only seen in episodes 3 and 16 of the Tokyo Mew Mew anime. In Tokyo Mew Mew, the girls were unnamed, but in Mew Mew Power, they were all called Becky, though their surnames were never revealed.
