Dr. Traum (ドクター·トラウム, Dokutā Toraumu) is the former major antagonist of Hug! Pretty Cure. He is the counselor from the Criasu Corporation's Azababu Branch Office. He is an elderly scientist who is Ruru Amour's creator and created her with the intent of replacing his daughter, who suffered an unknown fate. He develops inventions to use against the Cures and possesses the ability to empower Oshimaida into Wild Oshimaida. In episodes 36 and 37, he designs a time-manipulating mecha to freeze time on Earth and turns himself into a Oshimaida to confront the Pretty Cure All Stars before being defeated. He then leaves the Criasu Corporation and makes amends with Ruru. His catchphrase is "This week's surprise dondon mecha" (「こんしゅうのびっくりロンドンめか〜」, "Konshū no bikkuri dondon me~ka~"?).
