Carly Witwicky recurs as a human character in the Japanese continuity of *Transformers: The Headmasters*. Married to Earth's Cybertron ambassador Spike Witwicky, they have a son named Daniel. By 2011, the family resides at the Autobot base on Athenia. Her MIT background includes expertise in chemistry and electronics, though these skills see minimal practical use during this period as she primarily serves as a homemaker. She frequently engages in domestic routines, serving coffee during Autobot meetings and voicing concern for her family's safety. When Daniel abandons a meal to tend alien seeds, she passively observes discussions about the hazardous buridanka plant. Later, she questions Fortress Maximus's inaction during Decepticon assaults on Mars. During Spike's diplomatic talks with Decepticons, she and Daniel are taken hostage. When Galvatron (later exposed as Sixshot in disguise) demands Daniel remain on Earth while Spike works on Athenia, she volunteers to stay with her son. Following their rescue by Headmasters, she raises no objection to Daniel joining Autobot missions. She attends Ultra Magnus's funeral and exhibits profound distress when Spike is wounded in a Decepticon attack. Fortress Maximus employs telekinesis to aid Spike's recovery, precipitating an emotional family reunion. When Daniel requests to travel to planet Master, she suggests he stay on Athenia to assuage her fears, though Spike overrules this. A space ration consumed on planet Daira sparks Daniel's memory of her preparing similar meals. During a global Decepticon offensive, she and Spike board a flight to Santiago that crashes in the Andes Mountains. She plunges into a crevasse, losing consciousness. Daniel rescues her, carrying her out on his back. Confined to a stretcher during recuperation, she returns to America aboard the Queen World. Spike assumes her care, freeing Daniel to join the final battle against the Decepticons. After their defeat, she, Spike, and Daniel bid farewell to the Autobots as they depart into space. In a manga storyline following Mega Zarak's defeat, she strolls a beach with her family and Autobots. Soundblaster attacks, resulting in her capture by Slugfest and Overkill. Daniel ultimately rescues her.
