History
A member of Daredevil's circus troupe, Mermaid was born with an aquatic fin instead of legs and the ability to fly. When the Skull's advancement across America brought an end to Daredevil's circus, Mermaid and some of the other members were ordered by Captain America to travel to New York and seek training under the tutelage of Scott Summers.[1]
Confronting Summers in Central Park, the freaks convinced him to train them to be the next team of X-Men, which would fight together against the Skull. The X-Men were successful in this, and Mermaid remained a core member of the team in the years to come.[2]
When Captain America was killed whilst aiding Mar-Vell quest to collect items of power on Earth, the X-Men, including Mermaid, joined up to help the reborn hero continue his journey. The quest would take Mermaid to Hel Laboratories where she would meet the Ant Men, the Blue Area of the Moon to witness Mar-Vell kill the Supreme Intelligence with Thor's hammer, and help battle the Wendigo in Wakanda when Mar-Vell traveled there to collect the Cosmic Cube.[2][3][4]
The X-Men would stay in Wakanda and help the nation relocate to the Savage Land in order to escape the army of Wendigo that stalked them. There, Mermaid would help her fellow X-Men, Black Panther, Storm, and the Ani-Men destroy the Wendigo army which turned out to be the mutant Multiple Man. Following this the X-Men would remain in Wakanda, and would be targeted by Belasco and the Dire Wraiths until they were saved by Mar-Vell, and Machine Man.[4][5]
Later, Mermaid and the other X-Men attended the wedding of Medusa and King Britain.[6]
