Temacu (Japanese: ヒメカ Himeka) is a character of the day who appeared in The Heartbreak of Brock.
Temacu is one of the few girls to fall in love with Brock, who caught her just before she tripped and fell into a fountain. Since that moment, she believed she had to marry Brock, but the confused Brock didn't reciprocate. Later, Team Rocket attacked her father's laboratory and captured what they thought was a Pokémon, but it was actually Temacu. As she tried to get out of the balloon, she nearly fell again, but James caught her. This caused her to fall in love with James and want to marry him instead. Thinking they could get their hands on the Pokémon at the lab through Temacu's infatuation with James, Jessie and Meowth forced him to play along, even if it meant that he had to marry her, though James was uncomfortable with the idea.
To accommodate the new plan, Team Rocket changed outfits and made up a cover story about James saving Temacu from attackers for her father. Brock was heartbroken after he found out that Temacu had fallen for James. Soon, Misty pulled off Jessie's disguise, exposing the trio and prompting them to run away. When they were trying to escape, Misty ordered her Poliwhirl to attack James with Water Gun. Temacu, worried for James's safety, jumped in front of the attack and fainted as a result.
Later, Temacu's father explained to Ash and his friends that she had become obsessed with marriage since her cousin's recent wedding. Temacu eventually woke up, only to fall in love with the first man she saw: her doctor, who helped her to return her to her senses. This time, however, the feeling was mutual and the doctor proposed to Temacu at her bedside.
She has quite an unusual name. She explained to Ash and his friends that it was a combination of the first letters of the following Pokémon: Teddiursa "Te" (Japanese: ヒメグマ Himeguma "ヒ" "Hi"), Mareep "ma" (Japanese: メリープ Merriep "メ" "me"), and Cubone "cu" (Japanese: カラカラ Karakara "カ" "ka"). She also gave Brock and James their own combination nicknames to match their respective personalities.
