Spider Monkey AU

Upon returning prior to her father's request in order to finish training  MK, Fang's identity is blown, and after a while she's caught by the  Spider Queen. Where she's subjected to the same serum as the city was  during her takeover, and is turned into a minion of SQ.

After  Shadow Play, Macaque is put in an arena where he's pitted against Fang.  He ends up teleporting them both away. Decidedly using her to throw SQ  off his trail should they decide to follow. It works, but she's left in a  frazzled state and wanders the city. Where she eventually gets chased  down by the Huntsman, only for Red Son to notice and take chase. And in  the end save her. Where she's brought back to his hideout and given  treatment for her condition. It isn't much, but it's enough to  temporarily disable her hostility long enough for her to warn Red Son of  LBD going after MK. To which he makes it his sole duty to track them  down in order to stop LBD while also dishing out a swift revenge on  Fang's behalf.

Unfortunately for him, they are unable to make it  to them in time, and are eventually forced to evacuate the city back to  their families domain with Fang in tow.

Red Son eventually  crosses path's with the gang, and after a brief back and forth, allows  them to see Fang. (As per her request to be put under to avoid further  conflict in her possessed state.) Waking back up, she warns her father  of LBD going after the Jade Palace in the celestial heavens, wanting to  unleash pure chaos onto the world. And with what power she has now, she  has that choice. She claims that while she was under she was traversing  the spirit world, in hopes of keeping herself sane while also keeping an  eye on LBD and her plans. Now knowing what she know's, she plans on  visiting the Jade Palace herself and warning them of the oncoming  danger.  After briefly offering her his own plan, and a tear felt  goodbye, MKing finally lets her go. And makes it his mission in  attaining the weapon that will vanquish LBD.

(In a connection to  the Reincarnation AU, the crew manages to find the Samadhi's Fire, and  uses it to fight back against LBD. Fang manages to bring reinforcements  with the Celestial Armies, however during a tedious standoff where LBD  attempts to overthrow the army and the crew, LBD escapes her mount in an  attempt to avoid the flames. Fang, seeing this, steals Lao Tzu's  diamond snare and proceeds to use it to hold her back while the others  work. Unfortunately the fires grow uncontrollable and scorch the earth  and heavens, with Fang caught in the crossfires where she  subsequentially 'perishes')
