īig Mom's overall influence allows her to gather information about the backgrounds of people she is interested in, with said information being used to issue threats and demands. Even after being captured and held by pure seastone chains and kept under watch of the All-Stars of the Beasts Pirates, the crew continued to feed her sweets to keep her in a good mood, while constantly fearing her presence alone.
After regaining her memory Big Mom was also able to scare Queen of the Beast Pirates, with the later even admitting that he did not stand a chance in battle against her, despite having defied her when she was amnesiac over oshiruko earlier.
Big Mom's arrival during a battle between her crew and the Sun Pirates and Germa 66 brought great jubilation to her crew, indicating that her presence would likely turn the tide of the battle in their favor. Ironically, this fear makes Big Mom stronger due to the nature of her Devil Fruit powers. In fact, almost everyone, including her own children, has been shown to fear her. She is known to destroy entire countries over sweets and is intimidating enough that even her underlings Pekoms and Tamago, who are powerful in their own right, are afraid of talking to her when she is angered. While under Big Mom's protection, Fish-Man Island is protected from pirate attacks, indicating a powerful influence similar to that of the late Whitebeard. Those who marry her children automatically become part of her crew. She possesses considerable influence within the Underworld as well, having connections to the Vinsmoke Family, which leads the legendary Germa 66. Through her strength as one of the most powerful pirates, Big Mom has managed to amass a very powerful crew, as well as several strong subordinates such as Jinbe, a fish-man and former Warlord of the Sea, and Capone Bege, one of the members of the Worst Generation. Even the Straw Hat Pirates recognize that she could crush them quickly and easily if they fought her recklessly. When her fellow Emperor Kaidou, known as the strongest creature in the world, threatened to kill her if she came to his territory, Big Mom simply invited him to try and said he would not be able to dissuade her. The Five Elders have stated that she is one of the few people capable of stopping Blackbeard. As the only female member, this effectively makes Big Mom the single most powerful female pirate in the world. As one of the Four Emperors, Big Mom is one of the four most powerful pirates in the world.
