Not generally known to be a sentinel
Place of Birth
X-Men Unlimited vol. 1 #27
As Neal cradled Sanjit’s body, Shapandar quietly told Neal to run. She had discovered that she was a Prime Sentinel; humans transformed into sentinels and set up as 'sleeper' agents, unaware of their programming until a nearby mutant activated them (as in Neal's usage of his mutant powers).
“ "I am an Omega Prime. Within moments I will have reached my full combat mode–with my core programming to destroy creatures like you. It is becoming increasingly difficult to even think of you as human. Your only chance is to disappear. Get as far away from India – and from me – as you can. Assume a new identity... a new life." ”
Neal refused, saying he loved Karima. Karima begged him to leave, saying she couldn't hold on much longer. Neal was forced to flee.
Karima later resurfaces on the decimated island of Genosha, where she encounters Charles Xavier and Magneto. The two were able to disable her Sentinel programming and restore her mind, but the technological modifications to her body remained.
Karima stayed on the island with the others, working as a police officer to restore order. She is trying to adjust to her new form, which comes into conflicts with her Hindu beliefs. It is assumed she left the island with most of the other residents after Decimation.
The X-Men recently discovered a disassembled Karima, along with Lady Mastermind in a lab of the Fordyce Clinic that was testing on mutants to see if someone can catch mutation like a disease. Beast has reassembled her, but she appears to have lost part of her memory from the moment she got disassembled. Rogue officially recruited her onto the team to help fight the Children of the Vault.
Since then she was able to help fix a teleporter in the search to find Pandemic, helping in the fight to defeat him. After Rogue was infected with a virus by Pandemic and Cable took the team to his island so Rogue could be cared for. On the island, Karima helped the team and the island residents who were attacked by the Hecatomb.Omega Sentinel is possessed by Malice, who is now a digital entity instead of a psionic one, via email virus; thus, she unwillingly ends up joining the new Marauders in X-Men #200. Whether being part machine and part human will allow her to overcome Malice's influence has yet to be seen. The other X-Men, save Emma Frost, are unaware of her being possessed until they are attacked by her along with the rest of the new Marauders, including Mystique and Lady Mastermind.
