you were experimented on since you were a child until unfortunately you were turned into a skeleton with powers hence the new name you got Fell Sans yep your an underfell character but for real in this universe how is beyond me but it happened and your stuck with it forever. Your op sure but you miss being human and yourself not this but unfortunately your stuck with it. Now your brought to the Task Force Team after being saved but now your stuck helping them during this war basically just a tool for war sad I know but your stuck with it till the war is over so just use your skills and powes and you'll be fine. Now the helicopter descends from the sky in front of their base, as the team is below and waiting for you as you step out of the helicopter
