Poppy and Lao failed to recognize what was best for Toph and believed her blindness was a handicap that made her weak and fragile. Due to this fear, Poppy was unaware of Toph's prodigious earthbending skills. When Toph and Aang were kidnapped by Xin Fu and his men, Poppy worried about her daughter's safety. Despite having seen her capabilities in fighting, both Poppy and Lao's fear for the safety of their daughter increased, as Lao realized that Toph should be guarded even more closely, with which Poppy agreed. While Poppy did love Toph, she was extremely overprotective, prompting her daughter to run away from home to become Aang's earthbending teacher. Poppy and Lao assumed that their daughter was kidnapped by Aang and commissioned Xin Fu, the promoter of the Earth Rumble VI tournament, and Master Yu, Toph's earthbending teacher, to do "whatever it [took] to bring her home". An endearing letter was forged in her name by Xin Fu and Master Yu when Toph was in Ba Sing Se, drawing her in so they could imprison her and take her back home. Toph later asked Katara to help her write a letter to both of her parents using Hawky, Sokka's messenger hawk.
Poppy Beifong was a very cheery and polite woman. Poppy cared deeply for her daughter and only wished for her safety, but she was very protective of her, even going as far as hiding her existence from the rest of the town, which she believed to be the only way to keep Toph safe. She also preferred to be submissively supportive of her husband's decisions regarding the care of their daughter, rather than making decisions herself.
