Karina (Project Karina)

Project Karina was an attempt at physical replication of Kari's in an artificial Mentali body, initially derivate from the same initiative as the project that brought Mariko Shinon to life, as an attempt to save Kari's mind near her death. The result was an Aqua/Terra Mentali Hybrid with the same physical appearance and abilities as Kari but without the degenerative illness she had.

Frustrated Hope
Despite all efforts to develop this artificial host body for Kari's mind and memories, Kari dies before the maturing of the body as suitable host, not allowing a flawless replication of Kari's neural pathways. Seen as failure, Project Karina was discontinued shortly after Sarah's disappearance. Not wanting another incident like the one of Mariko, the artificial body was put on stasis indefinitely and locked away underneath Aspen Institute

Maturing
Falsely believed that Project Karina's maturing process was halted completely in the stasis, she wakes up about a thousand years later and breaks free from her stasis tube and escapes, without Kari's memories but with her personality. Another difference is how she developed psionic potential bigger than Sarah's, being a fully developed empath and telepath.

As result of stasis, Karina's hair is no longer black but white, being the single distinctive visual characteristic from Kari.

Encounter
Later in the same year, Karina finds Sarah and start remembering her from Kari's memories. Apparently the replication wasn't a total failure, with little snippets of memory having resisted, though Kari's past was completely lost
