Keemia Alavardo is the daughter of Alma Alvarado and Flint Marko aka Sandman. When Marko found out about Keemia, he took her to Governors' Island and built her a giant sand castle where she could live like a princess. Spider-Man rescued Keemia thinking she was in danger from the Sandman and she was put into a foster home. Sandman rejoined the Sinister Six in the hopes of getting his daughter back by force. When Doc Ock unveiled his Octahedron shield which allegedly could save the world from global warming, he made a list of demands. One of which was giving full custody of Keemia to Sandman.
