So the player (Wymar, Taya, whoever) is taken through a portal to this nebula. Inverse Montie is there, waiting to kill the player. For the bossfight, the player will use a large hovertank to fire at Inverse Montie.
75% - IM will shrink, but will still need to be confronted in the tank.
50% - IM will shrink again, and the player hops out of the tank to fight her.
25% - IM will shrink one last time, giving the player a better shot at beating her.
0% - Inverse Montie explodes in a cosmic blast of light.
Then another portal opens for the player to go through.
