Rebecca (Japanese: マナミ Manami) is a character of the day who appeared in The Punchy Pokémon.
Rebecca tried to convince her father, Anthony, to come home, but he told her he wouldn't until he won the P1 Grand Prix. Brock sympathized with Rebecca's feelings, so he and Ash volunteered to help defeat Anthony in the tournament.
Using a stolen Hitmonlee, Team Rocket nearly defeated Anthony in the semifinals. Rebecca, not wanting her father's Hitmonchan to get hurt, jumped into the ring. Anthony then took the hit himself, giving up his P1 Grand Prix chances. Anthony then decided to return home to his family, making Rebecca happy again.
