Sersi is an Eternal,[6] a race of people genetically altered from Humans to be superior in all physical traits.[12] She is a flirtatious socializer, often found hosting or attending parties,[7][13] and her expertise is matter transmutation, which she often uses to her own amusement.[6][14] Throughout the millennia, Sersi has been involved with numerous historic events, often accompanied by her long-time lover Makkari.[15] Despite her easy-going attitude, Sersi has risen to the occasion when necessary, including sacrificing herself for the sake of all life on Earth.[16] She has been a member of Avengers[17] and the short-lived New Breed,[1] and, despite all the darkness she's had to overcome, she hasn't lost her good disposition and is still one of the Eternals' most valued members.[18]
