Mew Marks are the marks people get when their DNA gets merged with an animal's. Ichigo Momomiya, Minto Aizawa, Retasu Midorikawa, Bu-Ling Huang, Zakuro Fujiwara and Ryou Shirogane all have the marks. Oddly, Berry Shirayuki has had her DNA merged with two animals, but it is unknown where her mew mark is. Some fans assume that she was too close to the injection gun at the time of her DNA infusion and as a result has the DNA entered her body directly without leaving a mark.
